6 Doc.02 /SM/C Mhz Bandplan DARC Committee C5.3 Introduction: The use of the calling system POCSAC is increasing strongly. To establish this network it is recomended the use of one common frequency. Most of the frequencies in the 435 MHz Band are used by other applications. Surplus Pager-equipment is used by a lot of Radio Amateurs in Germany nowadays. This equipment has been originally using frequencies between 450 and 460 MHz. In the light of the above a possible choice for the frequncy could be a frequency very close to 440 Mhz. Proposal: We propose to use the frequency 439,9875 Mhz for the POCSAC System.

7 Doc02/SM/C5.20 Deleting the General Footnote i in the 145 MHz Bandplan DARC Committee C5.4 Introduction At the Lillehammer Conference it was recomended to amend the text of note iii to the 145 MHz bandplan as follows: No packet radio networks will be set up in the 145 MHz Band. The words No access from the 145 MHz Band to Networks on other Bands will be allowed. were deleted. See also note h from the 145 MHz Bandplan. Now it will be possible to get Packet Radio access from 145 MHz Band to other bands. For this kind of operation it is necessary to use channelized frequencies. ( 12.5 khz spacing) The general footnote i ( 145 MHz bandplan ) says : In Europe no input or output channels of NBFM Repeaters shall be allowed to operate between MHz Because we are allowed to use a range of frequencies from up to MHz for automatic Packet Radio access ( Digipeatermode) and we are already using NBFM with digital modulated repeatersystems, it is consequently proposed: Proposal: Delete the footnote i from the 145 MHz Bandplan

8 Doc.02 /SM/C5.6 Page 1 of SUBJEC Interim Report of the Allocations Coordinator DK2NH C5.5 The frequency allocation table of IARU-Reg. 1 has existed for a long time. Its historical task was to provide an overview of all national allocations of the VHF/UHF and Microwave bands in the very sovereign Reg. 1 countries. The liberalisation of the 90 s gave a better look inside each countries frequency policy. But it is not complete. Supra-national organisations like CEPT with suborganisations, the European integration with new organisations interested in frequency policy, like the EU, economical interests and at least the new telecommunication-means gave more transparence. The historical World Radio Conferences, previously held every 4 years, became a continuous process in the field of frequency management. Everybody involved in this field must have up to date information and must be able to react immediately. The DSI-process, initiated by the ERC, European Radio communications Committee, showed how the frequency-world will proceed in the future. Similar actions initiated by the European Commission are in progress. National coordination groups work in this field. The overview of frequency allocations is a proper means to help each society engaged. Therefore, this allocation table has to be as precise an actual as possible. The future of the allocation table should be reviewed. What is the actual requirement of the table? Is there a need for more and detailed content? What is the necessity and what is the whish for content? What is the allocation managers task? Is it only to collect and govern the data?. Who uses the table? For what is the table to be used? Some other ideas for the discussion Reg. 1 has no frequency manager in its formal structure. Do we need one? As mentioned, not only on ITU-level, frequency policy is an ongoing process. Who looks to organisations like CEPT with ERC and ERO, like EU with possible new structures in that field? Who in Reg. 1 or C5 acts in this scene? How strong are the countries authorities now and in the future as (counter)-partners in the field of frequency policy ans usages? What is of more interest in the future? To upgrade the status of alloncations or to influence all parties involved not to overattack our secondary allocated bands? What do we really need in the future? Do we need more supra-national coordination in Reg. 1 or C5 for the efficient use of the bands beside the strongly increasing primary usages?

9 Doc.02 /SM/C5.6 Page 2 of 2 The Detailed Spectrum Investigation, DSI, was initiated to converge the allocations and usages in the 49 CEPT countries. The amateur-allocations are under some attack, but still remain in the most part. The secondary status was not contradicted in the DSI discussions. It seems, there is no interest to drop them totally. But in fact, the primary usage make it more and more difficult, to survive in the various countries. It seems, that especially the national allocations and the amateur usages of the UHF/Microwave-bands differ more than before in varios countries, contrary to the european integration process and DSI. It seems, in Reg. 1 everybody recedes to into local or sublocal positions, to prevent disintegration of the national amateur-community or of the societies of the country. Are these developments because of lack of information or content of the allocation table or the lack of interest in what is happening in other Region 1 areas. This could at least lead to the situation, that Reg. 1, or Committee C5 itself, is not able to influence the several supra-regional organisation with one coordinated opinion. I joined the DSI process from the beginning, on behalf of the DARC. Last year at a late stage, I had to comment and realign the late and not region wide coordinated and distributed statement of IARU Region 1. It caused no damage. But had I not been present, the amateur radio community would have remained in the public with differing opinions of what should happen with the frequency-bands in the future. It is necessary to focus on how the frequency allocation-(table) and more importantly the usage should be handled region wide. As a result of the discussion some ideas should be brought forward, how C5 and/or Reg. 1 will act in the future.

10 Doc.02 /SM/C SUBJEC Change of the 144 MHz bandplan (Linear transponder segments) VERON C5.6 Background Changing the bandplan in Tel Aviv 1996 resulted in a deletion of the Linear Transponder segment. Some radio amateurs in The Netherlands want an experimental Linear Transponder, a common IARU allocation for those experiments is advisable. Proposal Add in the usage column of the All Mode segment 144, ,794 MHz (144,800 MHz) a segment for Linear Transponder Output 144, ,660 MHz and Linear Transponder Input 144, ,690 MHz.

11 Doc./02 /SM/C APRS Frequency MHz VERON COMMITTEE C5.7 Background Due to the use of 144,800 MHz by APRS systems the current 144,800 MHz borderline needs to be shifted 6 khz downwards. The All Mode segment then ends at 144,794 MHz and the digital segment starts at 144,794 Proposal Footnote i: No inputs or outputs of Linear Repeaters shall be allowed to operate between 144,000 MHz and 144,794 MHz.

12 Doc.02 /SM/C cm Repeater shift in ON Band planning adjustment UBA Committee C cm repeater shift in ON Since the very beginning of the 70 cm in Belgium we have chosen the 1,6 MHz shift as used in PA and F. The UBA would like ton confirm this by adding our country prefix «ON» in the band plan just in front of the segment , so that the text will be NBFM repeater freqs (F/PA/ON), 25 khz spacing, 1,6 MHz shift (f) and in front of with the text Repeater input channel freqs (F/PA/ON), 25 khz spacing, 1,6 MHz shift Further, since the 12,5 khz shift has been used for 2 m repeater it has also been adopted on the 70 cm band. This could be also modified in the bandplan.

13 Doc.?? /SM/C??? The use of WJST (PSK 441) in the 144 MHz band UBA Committee C5.9 Background Early 2001 K1JT developed a software program called Weak signal communications by K1JT. The programs makes it possible to communicate via minimal meteor reflection bursts using high communication speeds. It employs 4-tone frequency shift keying (882, 1323, 1764 en 2205 Hz) with a speed of 147 characters per second (8820 letters per minute). Starting july 2001 the systems was expensively tested in Region 1 (Europe) especially during the Perseids, and this with a very high degree of success. The lack of planning (bandplanning and procedures) was experienced as a definite shortcoming, and resulted in misunderstandings and discussions. Therefore it is necessary to provide a proper place in the bandplanning table and plan proper operating procedures for the use of WSJT. Where? It has been established that most of the WSJT transmissions occur in the segment between MHZ and MHZ. Although strictly spoken WSJT is a digital mode, it isimpossible to use WSJT (PSK441) in the MHz segment, as, in the first place, it concerns the detection and reception of weak signals in SSB (USB). Reception of such signal in close vicinity of the typically strong digital signals in FM mode in that section of the band would be totally impossible. As this technique is only aimed at supporting meteor-scatter communication it also appears to be best to establish procedures which are similar to the procedures used in HSCW (high speed CW). Although the correct original denomination of this new mode os PSK441, it is best known as WSJT. Proposal Name: The official name of the mode is WSJT. Bandplanning: Calling frequency for WSJT is MHz. Procedure: Chapter Vb (Operating MS-procedures) of the VHF managers handbook should be adapted. Timing: periods used in WSJT are 30 seconds long Use of frequency: scheduled contact according the SSB bandplanning random contacts using CQ-calls is Mhz using the letter system as in CW. QSO procedures are the same as described in the handbook (point 7)

14 METEOR SCATTER DIGITAL MODES FREQUENCY ALLOCATIONS ON THE 50MHz & 144MHz BANDS RADIO OF GREAT BRITAIN Committee C5.10 BACKGROUND Meteor Scatter Digital Modes such as WSJT are increasingly being used for meter scatter communications. WSJT is an acronym for Weak Signal communication by Joe Taylor K1JT. It is a narrow-band digital system for weak-signal meteor scatter communications. The WSJT software uses a p.c. sound card to produce four-tone frequency shift keying at a 441 baud rate (FSK441). The audio tones are applied to the microphone socket of an s.s.b. transceiver. The bandwidth requirement is comparable to one s.s.b. channel. Short messages (conforming to existing IARU Region 1 meteor scatter procedures) are typed into buffer stores and are transmitted at a transmission speed of 147 characters per second, approximately 1764 words per minute. Messages are transmitted and received in 30 second periods. WSJT (FSK441) is therefore a narrow-band communication system specifically designed for weak-signal communications via meteor scatter. Numerous stations, both experienced meteor scatter operators and newcomers, are now using WSJT (FSK441) communications. Most WSJT (FSK441) work is being carried out on the 144MHz band with a smaller amount of traffic on the 50MHz band. Operators are currently using frequencies above MHz and around MHz. NOTING The IARU Region 1 band plan allocates MHz as the M.S. centre of activity. The IARU Region 1 band plan allocates MHz for RANDOM M.S. SSB. This frequency sub-band is now not used by meteor scatter operators, preference being given to the RANDOM M.S. SSB allocation MHz. PROPOSAL 50MHz BAND That the frequency of MHz be allocated for M.S. Digital Modes(WSJT (FSK441))usage. 144MHz BAND. That the frequencies MHz be discontinued for RANDOM MS SSB use. That the frequency of MHz be allocated for M.S. Digital Modes (WSJT (FSK441)) usage.

15 Doc/02/SM/C5.11 EXTENSION TO THE 70MHz BEACON SUB-BAND RADIO OF GREAT BRITAIN Committee Committee C5.11 BACKGROUND At the IARU Region 1 meeting, Lillehammer 1999, it was agreed that MHz and MHz be designated for use by the multi-band timesharing beacon project. However, the IARU Region 1 70MHz bandplan designates the beacon sub-band as MHz. An extension to the beacon band will accommodate the multiband beacon allocation. An extension may also be appropriate due to additional IARU Region 1 usage in Slovenia (S5) and South Africa (ZS). PROPOSAL To extend the 70MHz beacon band by 20kHz from MHz to MHz.

16 Doc/02/SM/C5.12 PRINCIPLES OF BANDPLANNING - CONFLICTS WITH EMERGING NARROWBAND DIGITAL COMMUNICATION MODES RADIO OF GREAT BRITAIN Committee C5.12 BACKGROUND The left hand column of IARU Region 1 VHF/UHF/Microwave band plans designates transmission modes and techniques such as EME, TELEGRAPHY, SSB, ALL MODE, DIGITAL, NBFM etc. Traditionally digital transmissions are placed in the DIGITAL MODES or ALL MODES section of the appropriate band. However emerging digital modes such as WSJT / FSK441 (used for high speed meteor scatter communications), PUA43 (for weak-signal VHF and UHF communications), EME-2 (for moonbounce communications) and PSK31 (an established transmission technique) now cause conflict with the established definitions shown in the IARU band plans. What sets these transmissions (and future techniques) apart from other transmission modes is that they are non-channelised, narrowband (less than 3kHz) and designed specifically for weak-signal work. Although digital in nature they are therefore appropriately located within the CW or SSB sections of the appropriate band. PROPOSAL That the left hand column of the IARU Region 1 band plans, specifically those areas marked as "EME", "TELEGRAPHY", "SSB", be redefined to accommodate weak-signal digital communications. If this is agreed then a sub-committee shall be formed to decided the correct wording. The subcommittee will then submit the definition to Committee C5 for acceptance during the conference.

17 Doc/02/SM/C5.13 NARROW BAND DIGITAL MODES FREQUENCY ALLOCATIONS ON THE 50MHz, 70MHz, 144MHz & 430MHz BANDS RADIO OF GREAT BRITAIN Committee Committee C5.13 BACKGROUND Narrow is a narrow-band digital mode currently allocated in the IARU Region 1 144MHz band plan on MHz. There are no allocations on any other VHF, UHF or Microwave band. PSK31 is a narrow-band mode comparable with CW and arguably more effective in bandwidth utilisation than CW. It is also a weak-signal mode. There is a significant difference between voice-bandwidth digital modes such as packet radio or RTTY and narrow-band digimodes such as PSK31. In practice PSK31 can accommodate several QSOs within a 1kHz bandwidth. For two years the frequencies as shown in the proposal have been allocated nationally within the UK. PROPOSAL That the following frequencies be allocated for narrow band digital modes usage, MHz, MHz, MHz, MHz. All are 'centres of activity' with operations +/- 5kHz of stated frequencies.

18 Page 1 of 6 Doc/02/SM/C5.14 AMATEUR PRIMARY SEGMENTS IN THE MICROWAVE BANDS RADIO OF GREAT BRITAIN Committee C5.14 INTRODUCTION None of the lower microwave bands have Amateur Primary allocations, although this has for many years been one of the IARU Region 1 objectives. There are, however, wide Amateur Primary allocations in many of the higher microwave bands, notably at 24GHz and above ( the mm bands ), mainly arising from WARC 79. At the same time, adjacent Amateur Secondary allocations were made. Unfortunately, because of the lack of affordable technology at the time the allocations were made, little use was made of them. Whilst the Amateur Primary allocations were implemented throughout the great majority of IARU Region 1 countries, many of the Amateur Secondary allocations were not implemented in a number of Region 1 countries where there was potential experimentation or activity. As soon as the technology became accessible and affordable, experimentation and activity began. In bands such as 24GHz and 76GHz, where there are both Primary and Secondary allocations, Centres of Activity have developed in both the Primary and Secondary allocations in different countries. This has led to a number of difficulties, namely: The existence of two different centres of activity within a band for the same type of activity, e.g. one in the Primary segment and the other in the Secondary segment, has divided the activity and hence reduced the number of possible contacts. The difficulty of making broadband equipment to cover both sub-bands that may be many hundreds of MHz apart, has kept the two groups isolated from each other. It is not possible to obtain permission from administrations for unattended operation in many Secondary allocations, because of the constraints of the Primary Users. Where permission for unattended operation in Secondary segments can be obtained, there are usually long delays (often several years).

19 Page 2 of 6 Doc/02/SM/C5.14 The use of Secondary allocations gives no protection against interference to or from Primary band users and may lead to loss of Amateur Primary status, where it exists, because of the lower levels of amateur activity in them. None the lower Amateur microwave bands have Primary status. Our objective of achieving Primary status in these would be more credible if amateurs adopted harmonised use of the Amateur Primary allocations in the mm bands where such status already exists. LOWER MICROWAVE BANDS All the lower frequency Amateur microwave allocations have Secondary status. With the increasing pressure on this part of the spectrum, the Primary users are imposing greater constraints on our operation, and it is becoming more difficult to obtain permission for unattended operation for beacons, repeaters and data nodes in these bands. This unattended operation is essential to stimulating activity in these bands. We need to seek to upgrade some of our Secondary allocations to at least Shared Primary status to cater for the these unattended activities, including enough room for the wideband modes such as TV. WRC 2000 ALLOCATIONS The changes in mm band allocations following WRC 2000 are given in tables 1, 2, 3 and 4 at the end of this paper. These changes are known to have been implemented in some Region 1 countries already, although the date for complete implementation is given as It is hoped that administrations will make both the new and the old allocations available during the changeover period. It should be noted that whilst the total bandwidth has remained broadly constant, the Amateur Primary Exclusive allocations that were made in WARC 79 have been lost and been replaced by Amateur Primary allocations that are shared with other Secondary users. This is a significant loss of status which gives less protection to the amateur services than before. Most of the bands still have a combination of adjacent Primary and Secondary allocations, and it would be desirable to encourage initial activity in these new allocations to focus on the Primary rather than the Secondary segments so that at least the segments used for international weak signal working are harmonised. RECOMMENDATIONS Recognising a) that there is extreme spectrum pressure on the amateur services from Primary users in the lower microwave bands, and that this pressure will eventually reach the mm bands, b) that the division of activity into two sub-bands is undesirable and,

20 Page 3 of 6 Doc/02/SM/C5.14 c) that the facility of unattended operation promotes activity and is more easily obtained in Primary allocations, The Radio Society of Great Britain 1. Endorses the IARU Region 1 policy of using the Primary segments of the Amateur allocations above 71GHz. 2. Endorses the IARU Region 1 policy of seeking Amateur Primary allocations in all amateur microwave bands. The Radio Society of Great Britain recommends: 1. That all member societies seek the immediate release of the new Amateur Primary allocations where these have not already been implemented, so that both old and new allocations will be available during the changeover period. 2. That a similar policy, i.e. use of Amateur Primary allocations, be implemented in the 24GHz and 47GHz bands, where Amateur Primary allocations exist but are not used in (most) Region 1 countries. 3. That narrow (say 2 to 10MHz-wide) Amateur Primary allocations, ideally exclusive, for weak signal working be urgently sought in all the bands from 1.3GHz to 10GHz inclusive, even if this means accepting more restrictions in the Secondary allocations, but not at the cost of losing such spectrum altogether. 4. That Amateur Shared Primary allocations wide enough to accommodate wideband modes such at analogue TV and repeaters, e.g. 2 x 20MHz, be urgently sought in all the bands from 1.3GHz to 10GHz inclusive, even if this means accepting more restrictions in the Secondary allocations, but not at the cost of losing such spectrum altogether.

24 Page 1 of 3 Doc/02/SM/C MHz BAND CODE OF CONDUCT RADIO OF GREAT BRITAIN Committee Committee C5.15 BACKGROUND At the informal IARU Region 1 meeting, Friedrichshaven 2001, there was a discussion regarding misuse by operators of the intercontinental DX section MHz within the Six Metre band. Those attending the meeting agreed that there was an educational problem and reference was made to the UK Six Metre Group voluntary operating code of practice for Six Metre operators. PROPOSAL A. To include the UK Six Metre Group voluntary operating code of conduct within the IARU Region 1 VHF Managers Handbook. B. For VHF Managers and other officers of national societies to actively promote the operating code of conduct in their associated magazines or other medium (e.g. Web sites, packet radio etc) as appropriate. In summary the proposed code of practice could cover. VOLUNTARY OPERATING CODE OF PRACTICE FOR SIX METRE OPERATORS. Please read these recommendations carefully and try to adopt their use in your everyday operating. SIX METRES AS A DX BAND It should be recognised by all 6M operators that Six Metres is a DX band as well as carrying normal amateur radio QSO's. All 6M operators should always treat each other with respect and tolerance. LOCAL BAND PLAN Always respect your local band plan as issued by IARU.

25 Page 2 of 3 Doc/02/SM/C5.15 LOCAL QSO's Do not cause nuisance and disturbance to other operators with local QSO's within the MHz to MHz DX window. LEARN TO LISTEN True Six Metre DX'ers spend about five percent of their time transmitting while ninety-five percent of time is spent listening and observing changing band conditions and propagation modes. This will be far more effective than just calling CQ DX at random MHz DX WINDOW The DX Window is widely accepted and should, in principle, be used for inter-continental DX QSO's only. The definition of what constitutes a 'DX' station lies with an individual operator especially when a station within your own continent constitutes a new country MHz INTERCONTINENTAL CALLING FREQUENCY This should be used for long-range DX contacts only. Do not under any circumstances engage in local continental QSO's on this frequency even for a minute or two. Do not encourage pile-ups on MHz MHz CQ'ING LISTENING is the first rule of working rare DX on Six Metres. So think twice before calling CQ on MHz. But the occasional CQ is good as it can discover an unrecognised opening. QSO TECHNIQUES Follow the style and take the lead of the DX operator in providing information. Otherwise keep it simple as there are other stations waiting in line. DX PILE-UP OPERATING You should listen to the DX stations carefully and not continue to call if they request a particular country or prefix if that is not you. You should NOT call if you cannot hear the DX station! SPLIT FREQUENCY OPERATION When a DX station creates a large pile-up, split-frequency operation is recommended. To minimise interference with other DX stations operating simplex, it is recommended that a maximum split of 10kHz is used.

26 Page 3 of 3 Doc/02/SM/C5.15 DUPLICATE QSO's It is always tempting to call a rare DX station every time you hear it. This should be avoided as it means that you are taking away the opportunity for the DX station to work a new station and give them their first QSO with the DX country. CW OPERATION CW is probably the best mode of operation on Six Metres due to the usually weak nature of many real DX openings. FM QSO's IN EUROPE All FM transmissions should be made above MHz for the obvious reason that FM is wideband and could wipe out weak DX signals. MUTUAL INTERFERENCE Proper adjustment of transmitters will minimise distortion and reduce interference with operators on nearby frequencies. The correct level of audio setting for the microphone in use is essential for readability and minimal distortion. Linear amplifiers should be only driven so that they operate in the linear region and in any case should only be used when propagation conditions require it. Please note that poor receiver performance with respect to adjacent channel rejection and overload will also limit your effectiveness.

27 Doc.02 /SM/C COMMITTEE C5.16 WSTJ/JT44 Frequencies VERON Background New techniques are not very often being introduced these days. We should give them the space they need in order to prove their benefits for experimental radio. The (alternative) random SSB frequency is hardly in use these days. In good showers, operators tend to move to +/- 144,300 MHz rather then going to 144,390 MHz. At the same time, there is a profound increase of WSJT *(1) activity going on around 144,370 MHz. Ever since the introduction of JT44*(2), operators tend to use the range of 144, ,170 MHz. This mode, though being digital, it is narrow-banded (app. 450 Hz maximum). It is therefore an acceptable class of transmission in the narrow-band area of the 2 meter band. The alternative EME band has never been used as such and suits this purpose very well. The proposed band-plan adoptions can thus been seen as a more a less formalization of the current use of this part of the 2 meter band in Europe. Proposal Allow WSJT in the range of 144, ,400 MHz on secondary basis to SSB operation. Drop the usage random recommendation of 144,390 MHz for SSB random use. Instead, recommend 144,370 MHz to be a random calling frequency for WSJT. Allocate the alternative EME band 144, ,160 MHz for the use of JT44 and possibly the lower 5 khz for PSK31, as an alternative to the PZK-proposal *(1)WSJT Weak Signal by (K1)JT,. A class of transmission using Phase Shift Keying like PSK31 primarily intended for Meteor Scatter use. It is currently also being referred to as FSK441. *(2) JT44 A comparable class of transmission as WSJT, but using slow PSK. It is narrowbanded compared to WSJT and is primarily intended for EME use.

28 Doc02 /SM/C5.17 APRS Preferred Frequency SRAL Committee C5.17 In the Lillehammer 1999 meeting a discussion took place whether it is useful to earmark a frequency within the Digital Segment of the 145 MHz Band Plan for APRS use. The discussion was not conclusive. After Lillehammer APRS people have iterated that it would be useful to have a note on the usage-column of the 145 MHz Digital Segment so that an APRS operator will know where to look for other APRS users even while travelling abroad. SRAL is of the opinion that use of 435 MHz and higher bands should be encouraged in digital communications. However, due to the fact that in Region I 435 MHz band differs from country to country, it is more urgent to seek a common frequency for APRS on the 145 MHz band. SRAL proposes that the frequency MHz should be marked as a preferred frequency for APRS use.

29 Doc.02 /SM/C5.18 Segment MHz SRAL Committee C5.18 In the Region I 50 MHz Band Plan the segment MHz has been designated as CW Only. There is another CW Only -segment, which is MHz. In practice very little CW activity takes place below MHz, although some EME activity has taken place there. There are several 50 MHz beacons within the Region I that operate below MHz. SRAL wants to invite discussion on - the best usage for the segment MHz - is there a need for an EME segment in the usage column in 50 MHz band plan - how could the beacon keepers be educated in a way that they would start coordinating the beacon frequencies with the Region I Beacon Coordinator It would be useful if the 50 MHz Band Plans from Regions II and III were available at the meeting.

30 Doc.?? /SM/C??? Segment MHz SRAL Committee C5.19 In the Region I 50 MHz Band Plan the segment MHz has been earmarked to be a segment for Intercontinental Contacts only. There are still societies in Region I, even within Europe, that do not publish this information in their magazines when publishing the 50 MHz Band Plan. It is our understanding that the idea behind this segment originated from 50 MHz DXers. It looks like it is the DXers that most often violate the recommendation to reserve this 30 khz wide segment for contacts between continents only. The current practice penalises only those who want to work according to the band plans. They can not work rare countries within their own continent, if the rare station stays within this segment only. SRAL proposes, that the segment for Intercontinental Contacts ( MHz) should be removed from the 50 MHz Band Plan.

31 Doc02/SM/C5.20 List of VHF Managers SRAL Committee C5.20 In each meeting we update the list of VHF Managers, Microwave Managers as well as Digital Communications Managers. However, in the Handbook there are people listed as Managers that we do not see in the meetings. Each society has been requested to inform the Chairman of the VHF Working Group whenever there are changes in the person or contact details of their Managers. To keep the information in the list of Managers up to date, the Chairman of the VHF Working Group is requested to send an (if address available) to each VHF Manager on the list to verify the information for the list of VHF, Microwaves and Digital Communications Managers each time that the Chairman is about to release an update on the Handbook.

32 Doc02/SM/C5.21 Segment MHz SRAL Committee C5.21 In the IARU Region I 145 MHz Band Plan the segment MHz has been indicated as an alternative EME band. Due to computer noise being concentrated around exact megaherzes (for example around MHz), EME activity has in recent years been moving upwards from the original EME segment ( MHz). In recent EME activity weekends (once a month) the activity has reached continously up to about MHz. Member societies are requested to inform their EME community about the alternative EME segment MHz. If there is a technical reason why the segment MHz is not suitable for EME use, this alternative EME segment should be removed from the 145 MHz band plan.

33 Doc02 /SM/C5.22 QSLs for Beacons SRAL Committee C5.22 There are may beacons on the air within Region I. Some of the beacon keepers would like to receive reports from people that can hear their beacon. Since each beacon has a callsign, the easiest way to send a listening report to a beacon keeper is to write out a QSL to beacon s callsign and send it via the QSL bureau system. Unfortunately it seems that in many countries the people running the QSL bureau are not familiar with the beacons running in their respective countries. The result being a card returned to sender marked with Unknown Callsign, Not interested in QSLs or some other meaningless information (meaningless when talking about a beacon whose keeper is eagerly waiting for any reports). SRAL proposes that member societies are requested to check that the QSL bureau of their country is aware of beacons operating within their countries, and that the bureau has a way to pass on the reports to the beacon keeper as long as the beacon keeper is a member of the society.

34 Doc02 /SM/CC5.23 WSJT need for a Procedure SRAL Committee C5.23 Lately new software called WSJT created by K1JT has gained popularity among VHF enthusiastics. This software can be used on meteor scatter contacts as well as on EME. Until now on meteor scatter computers have been used to generate and decode high speed cw. WSJT includes new features compared to the previous systems, for example a single tone possibility to transmit signal report or other information. It seems that there is a need to check if existing meteor scatter procedures have to be modified to include a possibility to use WSJT software. SRAL invites C5 to discuss this matter and if needed, to set up an AD-Hoc working group to make a more detailed proposal to the committee on this matter. For this discussion, member societies are encouraged to collect the opinion of their meteor scatter and EME people on using WSJT on VHF/UHF.

35 Doc02/SM/C5.24 Where to work on cw SRAL Committee C5.24 In IARU Region I Band Plans there are allocations for CW ONLY contacts. On the other hand CW contacts are allowed also outside this CW ONLY allocation. For example in the 145 MHz band plan there is a Telegraphy Calling frequency at 144,050 MHz and a SSB Calling frequency at 144,300 MHz. Nowadays, if a station from Western Europe, for example in UK, wants to call CQ on cw, he often goes to around 144,300 MHz to make his call while a station from Eastern Europe, for example in Finland, will go to around 144,050 MHz for his call. The logic the UK station is following is that by calling on SSB Calling frequency on cw will be heard both by stations waiting there for SSB calls as well as all those that are waiting for cw calls. The logic behind the Finnish station s choise of frequency is that this way his call will be monitored by the cw enthusiastics only without annoying those operators that do not know cw. Another point that the Finn keeps in his mind is that if one station uses 144,050 MHz for his call, another station located geographically close to him can use 144,300 MHz without suffering from the sideband noise. SRAL recognizes that on microwave bands there might be a need to concentrate the activity on one center of activity only. SRAL proposes that for cw/cw contacts on 145 MHz and 435 MHz bands operators are encouraged to use the CW ONLY portion. Crossmode contacts should take place outside the CW ONLY portion of the band.

36 Doc.02 /SM/C5.25 Definition of a Complete Contact SRAL Committee C5.25 In the VHF Managers Handbook one can find a definition for a complete Meteor Scatter QSO as well as for a complete Contest QSO (even with instructions on what penalties take effect in case a mistake takes place in a contest exchange). However, there seems to be no definition within Region I for a complete ordinary VHF QSO. Currently, a widely used definition within Region I is that a complete contact has taken place if callsigns and signal reports have been exchanged correctly during a contact. However, for example in the U.S., the definition of a complete QSO seems to call for exchange of callsigns plus one additional piece of information, for example the locator (known as Grid Square in the U.S.). As a result of this, a satellite contact between U.S. and Europe can be complete from the U.S. point of view but not complete on the European side (if only locator, not the signal report has been given by the U.S. operator). SRAL proposes that the definition of a complete contact shall be the exchange of both calls plus a signal report using the RS(T) system (special reporting systems like TMO for EME are allowed). Special care should be taken with the wording of this definition to accommodate pile-up style working (where in contacts not both callsigns are mentioned by the stations).

37 Doc.02 /SM/C5.26 Page 1 of MHz Bandplan Norsk Radio Relæ Liga - NRRL Committee C MHz BANDPLAN: FREQUENCY MHz FOR APRS - AUTOMATIC PACKET REPORTING SYSTEM (NRRL) OBSERVING that APRS (Automatic Packet Reporting System) is gaining increasing interest and is being increasingly used across Europe and other parts of the World. CONSIDERING that the frequency MHz has been adopted for APRS by users in most parts of Europe. NOTING that the IARU Region 1 allocation in the 2 m band is all mode, with no unmanned stations, below MHz; and digital communications above MHz. CONSIDERING that there should be no activity exactly on the band segment borders, which will modulate into the wrong segment; making it necessary to move the band segment border slightly downwards for APRS to be used on MHz. REALIZING that this proposal was thoroughly discussed and unanimously supported at the IARU Region 1 VHF/UHF/MW Committee Interim Meeting 2001 in Friedrichshafen. PROPOSING 1. that the following usage is added to the IARU Region 1 Bandplan for 144 MHz: MHz APRS (Automatic Packet Reporting System) 12 khz bandwidth 2. that the border between the all mode segment and the digital communications segment be moved from to MHz 3. that the following wording be adopted to the footnote i to the 144 MHz bandplan:

38 Doc.02 /SM/C5.26 Page 2 of 2 No inputs or outputs of non-linear repeaters shall be allowed to operate between and MHz. The expression non-linear is used in order to allow socalled linear repeaters, which linearly convert a segment in one band to a segment in another band.

39 Frequencies for PSK31 on VHF/UHF Polski Związek Krótkofalowców - PZ Committee C5.27 The activity in the PSK31 mode on the HF bands grows rapidly. The calling and operating frequency of PSK31 in HF bands lies in the exclusive CW bands. This mode, occupying 62Hz for one station, allows to work a dozen or so stations in a SSB pass band, without tuning of transceiver, and using about 3-10dB lower power than in CW for the same communications possibility. The frequencies are: PSK31 frequency CW exclusively band 3'580 khz 3'500 3'600 khz 7'035 khz 7'000 7'045 khz 10'140 khz 10'100 10'150 khz 14'070 khz 14'000 14'089 khz 18'101 khz 18'068 18'109 khz 21'080 khz 21'000 21'149 khz 24'920 khz 24'890 24'929 khz 28'080 (28'120)kHz 28'000 28'190 khz It is proposed to use the same principle for VHF/UHF bands, to put PSK31 in the exclusive CW band: 50'085 khz 50'090 khz (CW calling center) 144'085 khz 144' '150 khz (now 144'610 khz) 432'085 khz 432' '150 khz (now 432'610 khz) 1'296'085 khz 1'296'000 1'296'150 khz 2'320'085 khz 2'320'000 2'320'150 khz There is little experience with PSK31 on VHF, but designation of unified end part of frequency (085) for all VHF/UHF bands should help to meet each other on the band during CW activity, especially during a contest. The present large offset on 2m and 70cm does not help to make a PSK31 QSO. PZK VHF/UHF/MW Manager Zdzisław Bieńkowski, SP6LB Wiesław Wysocki, SP2DX PZK/IARU Liaison Officer

40 Doc02 /SM/C5.28 Change in Contest Rules IARU Region 1 PZK Committee C In the Region 1 September Contest Rules, quoted also for the October Contest, in p5, it has been stated: (VHF Managers Handbook page 111b-p1 Oct 99) Any telephony made with stations transmitting in the Telegraphy sub-band shall not count for points. In the log sometimes one station is logged as SSB (e.g ) and then as CW (59001). A Contest Committee cannot settle if there was a violation of rules as above, because there is no exact frequency of both stations, whether the SSB station was outside of telegraphy sub-band and the CW station was in the SSB sub-band. In order to exclude any misunderstanding, PZK proposes to replace the above mentioned sentence in p5 of therules with: Cross-mode contacts (SSB/CCW) shall not count for points.

41 Doc.02 /SM/C5.29 Proposal SSA Committee C5.29 Proposal for the IARU VHF-meeting in Vienna EME activities in the VHF frequencies have increased a great deal in the past years. However some problems have occurred in the lower part of the 144 MHz band because of interference from SSB stations calling in this segment. The band segment of 144,000 to 144,035 MHz, which today is for both CW and SSB should be exclusively a CW segment. The alternative EME frequencies 144,140 to 144,160 should also be divided up into two segments where 144,140 to is a CW segment and 144, ,160 is exclusively for SSB. Today we have a large number of low level computerised EME experiments taking place in the lowest segment of 144 MHz and these experiments are hampered by the presence of SSB wide modulation signals in this part of the band. The SSA proposal is therefore, that this lower segment should be reserved for exclusive CW transmissions and the alternative EME frequencies divided as suggested above

42 Doc02/SM/C5.30 Page 1 of 3 A new bandplan for MHz EDR Committee C5.30 A new bandplan for MHz? Second edition. The present situation: At present substantial parts of Europe only have access to 6 MHz of the 435 MHz band. Though the majority of countries do have access to the whole MHz band the 2 x 2 MHz at the edges have been subject to interest of other users and administrations. For a number of years we got used to share the 435 MHz band with other primary users like military radars, Syledis and real ISM devices. Most of these activities have now ceased - BUT: More than a decade ago some new secondary services were allowed into the ISM part of the band: 433, ,790 MHz. Since then the use from these services has evolved. Recently the industry succeeded in introducing SRD's for data communication with a duty cycle of 100 % in the ISM band! (ERC rec , Annex 1) Opposition against the proposal was raised from only two administrations: The Finnish and The Danish on behalf of SRAL and EDR. The IARU, Region 1, representative accepted (reluctantly) the recommendation! The MHz band is crowded with Low Power Devices, Short Range Devices etc. and the activity is still rising! The ERC rec will only accelerate that development. The problems: The narrowband segment: MHz seem to have fewer problems than before as many military radars and Syledis systems is now outdated. The MHz segment is a mess due to Low Power and Short Range Devices all over the place! For the next decade the use of such devices will grow. Devices carrying telephony and 100 % duty cycle data transmissions represent the biggest problem. Though these types of devices recently got their own sub-band in the 850 MHz range they succeeded getting access into the 434 MHz band as well - and will definitely stay. The
