2 Announcements Amateur Radio Volunteers Face Fire Threat While Supporting Emergency Communication The North-Central Washington town of Republic touts air you can t see on its website. That s not the case today. Wildfires in the US Northwest have not only hampered the air quality and visibility, but led to a Level 2 evacuation order in the Ferry County community of about 1000 residents. That could rise to Level 3. Amateur Radio volunteers in Ferry County have been on the front lines of the wildfire emergency there. In Republic, a combination of Ferry County Search and Rescue (SAR), Community Emergency Response Team (CERT), and ARES/RACES volunteers have been supporting communication for a shelter housing some 4 dozen evacuees with more to come, according to Ferry County ARES Emergency Coordinator and RACES Radio Officer Sam Jenkins, WA7EC. We are now close to our maximum support level for local volunteers, Jenkins told State RACES Officer Monte Simpson, AF7PQ, who also is ARRL Western Washington Section Manager. We are now expecting to operate for several weeks at the Republic High School. The firefighters say they are going to attempt to defend our emergency operations center/emergency shelter at all costs, Jenkins added. We are standing our ground. In addition to being the Ferry County ARES EC and RACES RO, Jenkins explained, he also heads the SAR component of the dual Ferry County SAR-CERT contingent. I have networked these three units together over time to increase the effectiveness of our small, poor, but valiant teams, he told ARRL. Firefighters from several states and British Columbia, Canada, have been working the Kettle Complex of three fires in Ferry County, which covered nearly 60,000 acres as of August 26. No injuries have occurred and no homes have been lost. Support teams from the Washington National Guard are assisting fire managers to ensure safety. West of Republic near Omak, the Okanogan Complex at more than 280,000 acres is now the largest fire complex in the state s history. According to the National Interagency Fire Center (NIFC), wildfires continue to burn actively across the West. The NIFC reports that 66 large fires or complexes have burned nearly 1.6 million acres in 11 states. Twelve fires are burning in Washington alone. Jenkins said his team of volunteers would like to have additional support, but, he told Simpson, I would expect that it is asking a lot for anyone to leave the comfort of their home to travel to a place where the smoke is so thick you can cut it with a knife, and not know if they would escape. Radio amateurs responding to the wildfire emergencies have been using VHF repeaters as well as HF on 75 and 40 meters, including SSB and digital modes, and IRLP. We are doing our best at doing our thing, Jenkins said. I am concerned about what is happening in our sister counties.

3 Highlights from our August meeting. Attendance: 9 Meeting was called to order by President Tom Howe KE7TEG A quorum of Officers was present. Minutes of the July meeting were read and accepted Treasurer's Report $ Randy N7CKJ ARES Report - No Report PARC Net No report Board Report Bruce KC7H led a discussion regarding Tom s role as president. He does want to continue his role as club president until the end of year, he will however, notify Gimmie AL7LB, and Jim WW7DD if he is unable to attend a meeting. Announcements: Randy N7CKJ announced that he has been dispatching the helicopters for the fire base at work, and said it was pretty interesting. Eating before the meeting will be at Rancho Chico s Old Business: Debbie KF7GUB would like the club to sponsor a water station for the Blazing Saddles event, as well as offer radio support. There was a discussion about whether this would benefit the club. Gimmie, AL7LB made a motion to co-sponsor the station with Debbie which was approved. Purchasing a club banner was brought back up by Debbie KF7GUB, there was discussion about the cost and whether to do one or two. Debbie made a motion to purchase two banners for not more than a total cost of $ Bruce KC7H, made change to the motion to purchase two banners about 12 sq.ft for no more than $ Motion was approved. Board members asked Debbie to send them a proof of the banner before it was made. New Business: The club picnic will be September 12 th at Jim Tills W7JWT place at 2027 Black Lake Rd, off highway 20 E. There will be a meeting at 11:00am followed by a pot luck picnic. Meeting was adjourned. Respectfully submitted by: Edward L. Zeiser, Secretary 3

6 The Radio Corner by Jim W7JWT The Heathkit AT-1 Transmitter It's time to remember back to our early years of Ham Radio. How many of you started out as Novices. No not a novice inexperienced operator, but getting our first ham license, the Novice Class. How many of you started with a Novice Class license? What year? I got my Novice Class license in 1972 at the age of 18. My call was WN9LAM. The N stood for Novice Class. What was your first transmitter? Mine was a Heathkit DX-60B. No, that is not what the article is about. It is about Heathkits' first ham transmitter, the AT-1, (Amateur Transmitter Number 1, how creative!). Heathkit introduced the AT-1 in 1951 when ham radio was in a simpler time. This coincided with the FCC implementing a new ham radio licensing structure which included a new introductory class, the Novice. Novices were allowed privileges in small CW segments of the 80 and 11 meter ham bands. See, it's OK to say you got your start on 11 meters! They could run up to 75 watts input power but the transmitter had to be crystal controlled. The AT-1 offered an inexpensive transmitter for the novice that could allow him or her to use additional features after upgrading to a higher class license. The three tubes AT-1 ran 35 watts input, CW only with crystal control. The AT-1 did have connections for an external VFO and an AM modulator. Heathkit introduced the VF-1 VFO in 1952, but never offered a modulator, per say. The AT-1 sold for $ It was the lowest possible dollar-per-watt price of the early 50's. The AT-1 is shown in figure 1 below as it appeared in a 1951 Heathkit flyer. SPECIFICATIONS: Range... 80, 40, 20, 15, 11, 10 meters. Oscillator-multiplier... 6AG7. Amplifierdoubler... 6L6. Rectifier... 5U4G. Panel mounted crystal socket, stand-by switch, key click filter, A.C. line filtering, good shielding, etc. VFO or crystal excitation--up to 35 watts input. Built-in power supply provides 425 volts at 100 MA. Size /8 inch high x 13-1/8 inch wide x 7 inch deep. The kit price includes all circuit components, tubes, cabinet, punched chassis, and detailed construction manual. How can you beat this! 6
7 Circuit Description: The AT-1 circuit consists of three sections, the power supply, an oscillator - multiplier section and the output amplifier - doubler section; each uses one tube. A schematic of the AT-1 is shown in Figure 2 below. Figure 2 The transformer power supply section uses a 5U4GB rectifier tube in a simple full-wave, capacitor - choke - capacitor circuit. The transformer provides 860 volts AC center tapped, 5 VAC for the rectifier filament and 6.3 VAC for the other two tube filaments and the accessory socket. Each filter capacitor provides 4 µf by series connected 8 µf capacitors. A pair of series bleeder resistors complete the supply. The standby switch opens the secondary HV center tap lead to remove voltage from the oscillator and amplifier when receiving. The oscillator uses a 6AG7 metal octal pentode as a grid-plate Colpitts crystal oscillator. The plate circuit can be either untuned or tuned and when tuned the stage may operate as a multiplier. The frequency of the crystal used depends upon the band, as shown in Table 1 below. 7
8 The amplifier stage uses a 6L6 metal octal tube. On 80 meters it runs straight through and on the other bands, depending on the crystal used, it acts either as a doubler or runs straight through. The output stage does not offer a Pi network, which is not yet well known; instead it is link coupled and loading for best output requires an antenna tuner, such as the AC-1. Though the ad says 35 watts input, the Heathkit manual more realistically specifies the AT-1's input power at watts. TVI: Television was finding its way into homes in the early fifties and TVI became a dilemma for many hams. The AT-1 took a series of precautions to help prevent TVI. The AC power line leads were bypassed, shielding was used throughout the AT-1 and the manual included a chapter on TVI including how to build a low pass filter for the transmitter, a high-pass filter for the TV and an RF line filter for the AC line. Controls: The T-1 is simple to operate. The front panel is laid out in three rows. The top row just has a basic meter that measures grid or plate current. The second row has the Driver tuning control (0-10), the Band Switch (80M - 40M - 20M - 10M) (the 10M position is also used for 11 and 15 meters), and the Output tuning control (0-10). The third row has the Crystal socket, power OFF - ON, meter switch marked Current (Grid - Plate), Plate-on - Standby switch, and a 1/4" Key jack. On the rear, left to right is an octal socket for an external modulator, the power line cord, an SO-239 antenna connector and a second octal socket for an external VFO. The modulator socket requires an external octal plug that shorts pins 3 and 4 for normal operation when no modulator is in use. Conclusion: The Heathkit AT-1 was manufactured through By then the higher power DX-100 had become very popular with advanced hams and bred the DX-20 and DX-35 as replacements for the AT-1. Many new hams, starting as Novices in the early fifties, used the AT-1 as their first transmitter. The AT-1 can still be found on ebay. They sell on the average of $100 each in very good shape and a collector grade unit can go for over $300. Ones in less than good shape can be had for under $30. This is based on the Orange County Amateur Radio Club article, Heathkit of the Month #25, by Bob Eckweller, AF6C. 8
