2 Start with Repeater Operation What is a Repeater? Station usually in a high location Repeats what it hears so others can hear Why start there? Greatly increases your range Watering hole people listen to frequency

3 Repeater Operation Rx > Tx Tx PL Rx Frequency Set the Rx frequency ( ) Offset (shift) 2m: 600 khz, UHF: 5 MHz PL tone (CTCSS) Sub-audible tone access

6 Popular Freqs Northern California 2 Meter Band Plan CW SSB SAT DIG PKT EXP DIG SAT Repeater Repeater Repeater SMPX Repeater Repeater SMPX Repeater 20 Ch khz Spacing 15 Ch khz Spacing SSB Calling (USB) APRS Digital data repeater Remote bases Calling frequency Red Cross. d Coordinators FM/Repeaters Packet Satellite Every region has some differences Go by the regional coordinators band plan first Then ARRL band plan.

7 Repeater Inputs UHF Band Plan 25 Ch khz Spacing Repeater Outputs Links Satellite Experimental Popular Freqs SSB (USB) D-Star C4FM Simplex CW / SSB ATV Links

8 Transmit Offset or Shift The transmitter s offset from the Rx frequency Where the repeater listens Standard offsets 10m 100 khz 6m 1.2 MHz 2m 600 khz MHz UHF 5.0 MHz MHz MHz

9 CTCSS - PL - Channel Guard Names for the same thing Continuous Tone Coded Squelch System Private Line (Motorola) Channel Guard (GE) What is it 32 standard sub-audible tones between Hz Deviation < 600 Hz (Voice peaks at +/- 5 khz) Allows multiple repeaters to co-exist on the same frequency PL Tone 5 khz Adding voice modulation

10 CTCSS Decode Rx PL > Tx PL Tx PL Bob Rx PL Joe Rx PL Only hear stations that transmit the same PL Useful for areas of high interference Listen only for members of my group

11 Digital Coded Squelch (DCS) - DPL Same application as CTCSS Sub-audible tone bits per second 104 Digital Codes Less likely to false than PL 9 data bits + 11 check bits + framing bits 3 digit octal value

12 Narrow vs Wide FM In 1975 Wide = 15 khz Narrow = 5 khz Today Normal (wide) = 5 khz Narrow = 2.5 khz FM Deviation

13 Narrow vs Normal (Wide) FM Normal (Wide) 20/25 khz channels Amateur radio GMRS MURS Old public safety & land mobile radio Narrow 6.25/12.5 khz channels 900 MHz amateur radio repeaters FRS Part 90 public safety & land mobile radio

14 Frequency Guides NARCC Web site & repeater guide ARRL Repeater Directory IOS & Android Apps

15 Digital Voice & VOIP Modes Digital Voice D-Star - Yaesu C4FM - DMR - P25 Growing interest Highly fragmented, incompatible systems Don t wait for a single standard Really fun new modes Jump in! VOIP Systems Connect radio systems through the internet IRLP: >1,600 connected repeaters world wide Echolink: >200k people and repeaters world wide

16 Try The Other Bands and Modes MHz CW MHz CW MHz CW MHz CW, RTTY/Data MHz CW, Phone CW can be really fun and great for DX and QRP. Use your computer/phone to decode if needed. Work the world when the band is open! 6 Meters 6 meters opens up for long distances 222 MHz 900 MHz 1.2 GHz Lots of repeaters on the other bands as well.

17 Getting On The Air - Repeaters Pick a repeater and program your radio Listen for a few minutes No traffic? Announce your presence K6BEZ Listening, Anyone on frequency? Not: CQ CQ CQ This is K6BEZ Round table QSO in process Wait for a pause in the action K6BEZ

18 What Do I Talk About? Basic (boring) QSO Call, Name, Location, Radio, Weather, Traffic More interesting QSO What are your areas of interest in amateur radio? What motivated you to get your ticket? What projects are you working on? What other hobbies or interests do you have? Why did you choose that radio? I need some advice on Did you attend Pacificon / Hamvention / Etc.?

19 QSO Lingo CQ CQ CQ - General call to any station Q-Signals Can be statements or questions. QTH Location QRZ Who is calling me? QRM Interference from another station QRP Low power QSO Two way radio contact QSL Verification of contact QRT Going off the air Signal reports RST You have a solid 59 signal here Readability 1-5 Signal Strength 1-9 Tone (CW Only) Best regards

20 Getting On The Air FM Simplex National FM calling frequency Establish a connection and move (QSY) to another working frequency Controversy Using 52 as a chat channel Calling Channel

21 Getting On The Air SSB Operation just like HF SSB but local Use USB (Upper Side Band) Antennas horizontally polarized? Not really Popular during contests EME (CW) General CW and weak sig EME and weak-signal SSB National SSB calling frequency General SSB operation Propagation beacons
