Reading that made me think of an Ham that had a TX in a rack, with a 807 in it. I'm thinking Miller was the maker of that piece of gear but not sure if that name is right or not. It was a long time ago, and I have the first sign of old age. -snip- HG> 1955 was the big year when I built a SSB exciter, a chinese HG> copy of the Central Electronics 20A.

The choice of PA tube was due to the 150W PEP HG> and CW limit. AM was limited to 50W. You were already using a Ei-Mac 4-65A before I became a Ham. While I was in the Navy I saw a Electronic Technician working on a VHF or UHF TX that had a 4-65A in it, and after reading up on the specifications I fell in love with the tube. I liked the looks of the tube. IIRC the 4-65A(s?) was/were used as the Modulator in a AN/GRA or AN/GRC TX (or TX/RX?) for Air Traffic Controllers on the Aircraft Carrier to talk to Pilots to give them instructions on when they could land their Plane. I dreamed of having two 4-65A's in a HF Final Amp but never did. I have a antenna tuner with plug in coils for 20M and 80M, but never used it. Another Ham built it. Here is a listing of the Ham Radio Gear I've used at my QTH. The first HF gear I used was a Hallicrafters S-38E until I got a used Hallicrafters SX-42 and a RME DB-20 preselector. The TX was a Heath DX-40 and Knight VF-1 VFO. My Antennas were a 40M Dipole for 40 and 15 Meters, and a Gotham V-80 Vertical for 80M. Later I had Drake 2-B, 2-BQ and Heath TX-1 Apache until I got a Kenwood TS-520S. I used a 20M Inverted Vee and a 80M Slinkey Antenna until I removed the wiring going up to the attic from the basement. I have a Autek Research QF-1 Audio Filter connected ahead of my speaker. The only product from Central-Electronics that I have is a GC-1 Gated Compression Amplifier. I still think of the C-E 100V and 600L I used at the Ham Shack at the Navy Base in California back in the early 1960's. Touch a few knobs to match the frequency I was listening to, and start transmitting on SSB, CW or AM. A Ham I met while I was in California told me he would zero beat someone talking on AM with his C-E 10A, and use their carrier to make QSO's with other stations. The AM'ers didn't care much for him doing that on 'their' frequency. The operator of the 10A enjoyed hearing them get upset back in the early days of SSB operating. C-E used Phasing for SSB, I remember reading about a Balanced Modulator circuit being used for SSB also. For 6 Meters I have a Heath Sixer, though I stopped using it when my neighbor across the street mentioned he could hear me on his TV, I didn't want to ruin the shows he was watching on his set by my jabbering with other Hams so I am QRT on 6M. For 2-Meters I used a Regency HR-2 and a Kenwood TR-9130. The TR-9130 developed problems staying on frequency and it couldn't be repaired. The last time I turned the HR-2 on I couldn't hear anybody on it. Maybe I will get another 2M XCVR and get back on the air some day. I enjoy reading Anateur Radio BBS echos to see what's happening on the ham bands while I'm QRT. HG> In 1957 the entire family moved to Mariehamn on the Aland HG> Islands after my XYL (OH2QJ) and I (OH2OJ) had first made a SSB HG> DXpedition to the islands to put that country on the SSB map. The OH prefix is Finland, DX Zone 15. EV> I put together a Heathkit FM Tuner to use with the Heath AA-32 EV> Stereo Amplifier for my Hi-Fi setup. EV> That's as close as I've gotten in receiver building. HG> I have built a lot of Heathkits both for myself and for HG> customers that didn't they were capable to do it themselves. A HG> National and a couple of Eico transceiver kits were also built. A man and his son had built a Knightkit SW Receiver and asked me to help them to make it work. They gave me the RX and the manual. When I looked at the picture in the manual of where the parts are placed on the RX chassis, I saw two wires were soldered to the grounded terminal and one wire was on the isolated terminal. The fix was switching the wires on the terminal strip and soldering them back. HG> I still have a Heathkit Monitor Scope and d:o Panadapter on my HG> ham desk. Some Heathkit and Eico Kit units for my radio/TV HG> service are now stored in the apartment. I got a VTVM, VOM, Digital Mulitmeter & Audio Signal Tracer on my work bench. Someone built a 2 inch Scope kit included with a Radio-TV course took through the mail, and gave it to me but I never learned how to use it like another Ham I know does.

I will raise the top cover if it is hinged to look around a new piece of radio gear, but I don't look under the chassis right away. I'll read the manual and look at the schematic pages to try learning how it works. When I was a SWL, the Midwest SW Radio I had, stopped working and I looked under its chassis. One part I remember looked strange to me, between the two ends that had wires coming out from it, the middle of the part was braided wire. The schematic showed it was a Resistor. Have You seen any Resistors that looked like that when You repaired someones product? 73 ....
