Look at the underside of the bandpass board and check it for cold solder joints. This was a minor problem on some early Corsairs. The coil wires were a little tarnished and did not have good continui
What's this about a Scout II? I didn't hear about it. I thought that the Argonaut V replaced the Scout. Also, it was the 1940's vintage AN/CRT-3 rescue transmitter that had the reel out antenna. Bob
No, I don't remember it that way. The problem was over the name "Triton" because Motorola had a marine radio called Triton. I don't believe there was a lawsuit, I think Motorola threatened legal acti
That's the one thing that makes me nervous. I opened the jumper when I was in MARS and reconnected it when I left the MARS program. Now its open again so that I can work the 60 meter band. I wish Ten
Yes, even before bundled cable, when long parallel lines were run on the telephone poles, the wire positions on the poles were periodically interchanged. One wire was dropped under the other and cros
Mike: My Scout seems to like dynamic mics. I have used a Cobra CB mic and a Shure CM14A "controlled magnetic reluctance" mic with good audio reports. They seem to sound a little better than the Ten T
I recommend the 500Hz filter in the second IF and the 8 pole SSB filter in the first IF. Original Corsairs had a 4 pole filter in the first IF, but changing this filter makes a noticeable improvement
Jerry, on the 1220, add C86 the "optional" capacitor. However, what really fixed it for me was adding a .01 uf cap in parallel with C36 near the PLL circuit. Put the cap on the foil side of the board
The NYE paddle is pretty rugged and not too big, but it uses leaf switches which don't have as nice a feel to them. Its OK, just not terrific, but a nice rugged paddle for portable or mobile use. The
Don: It is normal for the tuning to be stiff. The knob drives a screw that runs the slug in and out if the VFO coil. A little light grease on the screw threads may help, but its not the kind of dial
ED: Yes 15 watts in the tune position is correct. On the meter lower scale there are 3 dots. The left one represents 1:1 SWR. The middle one is 2:1 and the right one (dot is just under the "10" on th
You will have to play with the temperature compensating capacitor in the PTO. Each PTO was individually compensated with a small N750 capacitor. The cap may not have a value shown on the schematic, b
Brian: In addition to caps, check the final tuning and antenna SWR. My 1220 was emitting a motorboating sound when I used certain mobile antennas. The problem could be a parasitic oscillation in the
If the counter is like the one in the Corsair (I), it could be caused by a bad programming diode on the counter. I had a disc ceramic cap fail on the counter board that caused erroneous counter prese
