I sure do wish we could have seen this thread stay alive without all the trash that got wrapped up in it! How about another story, then? Back in the early 1970s I was active in the section and region NTS nets. CW of course! We handled all sorts of traffic in all sorts of conditions. Even my modest homebrew setup was effective on 80 meters EPA and 3RN. Being a regular scheduled NCS and region rep for EPA while still in high school is an experience I'm gald I didn't miss. Now of course in such net operations one becomes very familiar with the other regulars - to the point that all you need is to hear a few letters of their signal to know who it is. Net members helped each other in various ways, such as locating inexpensive parts, antenna parties, etc. One year I was looking for something different to do on FD, so I asked around if anybody needed operators. Two hams who weren't that far away offered to let me join their group. Turned out they were into QRP CW, back when such operations usually meant homebrew, because the manufacturers hadn't caught up yet. So I wound up on the banks of the Schuylkill with "The Schuylkill River Rats". The four of us put up a simple parallel dipole between two trees, set up a surplus tent, table and chairs, and ran a pair of cables over to the battery in someone's car. Hooked up the rig and we were ready to go. Now the rig we used was something unique. It was homebrew, of course, covering 80 and 40 meters. It was a transceiver, with all solid state devices except for the driver (12AU6) and final (1625) tubes. With a small external power supply for high voltage, it could run as low as 5 watts for the QRP class or as high as 75 watts for home use. We ran QRP, of course. The receiver part was direct-conversion, with a phasing-type system to eliminate the unwanted sideband. It worked pretty well, particularly since it only had to deal with a relatively small audio range, since CW needed only a small audio pass band. It was built in the chassis of an old early-1930s-vintage National FB-7 receiver, using only the case, tuning capacitor and dial. That FB-7 would be worth a lot more today in its original condition, but back then "old stuff" was all over the place for rock-bottom prices. We made quite a few QSOs with that setup. IIRC something like 330 QSOs with just 80/40 QRP CW and the dipole. I learned a lot about rig design, QRP operating and Field Daying with a small group. When it was done, taking the setup down was a breeze - we were on our way home in an hour. I was skeptical about whether the engine in the battery-supply-car would start, but it turned over and caught first time. Maybe cars had bigger batteries then, or perhaps it was the old Dodge Slant 6... In any event, that started my interest in serious QRP and small-group FDing. (fast forward more than three decades) A few months ago, a local ham gave me a pile of stuff he just wanted to be rid of. Among the pile were a bunch of old copies of the magazine "ham radio" (they didn't use capitals - trying to emulate e.e.cummings or k.d.lang or some such). They were all early issues, from 1968 to about 1975. I'd never been a subscriber but I had read a few of them, back in the day. Once they were properly stored, I pulled out a copy at random to read - July, 1969. Flipped through it and suddenly got chills - there, on page 14, was the FD rig we'd used so long ago! Article was by the leader of our group, Cliff, W3NNL, who had designed and built it. Boy, did that bring back memories! 73 de Jim, N2EY |
