K5AF, Thank you for your 160 meter story. I also have a history of using Heat products in non approved ways ! Back in the 1950's made some VF-1 QSO's probably on 40 meters. Also some of the local kids and I made some good QSO's with each other using the Heath GDO as the TX. Coupled to the antenna with a 1 or 2 turn coil and a key in series. However we had a problem, good signals with the key up, but not with the key down. Finally found each other's key down signals by tuning our RX's way off frequency. Good signals between our shacks about a mile apart, but hoped our drifting FSK signals would not reach FCC about 10 miles away, so our few QSO's were very short. Fast forward about 55 years and I had made a few 160 meter QRP QSO's from my home in Alaska with only an inverted L and a minimal radial field. This was using my big transceiver just turned down to 5 W, so being a QRP fanatic, I did not really count this. So I needed to build a battery powered 160 meter set up before the next contest. For the TX, I dug out my old Heath HW-8, and set it up for 3.6 MHz. I then padded the few watts down about 10 dB and fed this into a 74HC74 divide by 2 chip, then into several parallel sections of an octal inverter chip. I fed this into a power FET and a kluged 160 meter LPF. I had 5 watts output with a 12 volt battery. Some key clicks, but no active local hams within about 40 miles on that contest, so doubt I caused too much angst among the contesters. Worked about 6 states and I believe Canada and Japan in a relatively few hours. I think most of the QSO's were between about 1500 and 2500 miles, but my signals were very weak. Conditions were exceptionally good, and most of the QSO's were after midnight and took some effort on the other poor guys. For my RX, I tacked some 1500 pF capacitors across the input filters on my KX-1, which improved it's RX by about 45 dB, so it was now band noise limited. So a future project is to build a small battery operated 160 meter transceiver with proper keying, and filtering. I may build a small transverter for my KX-2, or possibly modify something like a 30 meter MFJ Cub for 160, or just design and build from the ground up. In my 67 years as a ham, I have spent ten times as many hours building as I have spent operating. After I build something and make a few QSO's, I often tear it down and start over again on an "improvement" (hopefully). It has been a good ride for 67 years, and hope I have many more QRP adventures. Rick KL7CW, Palmer, Alaska
