I found that a generic 2N2222 worked identically well to the Q1 transistor originally in this receiver. Try that, if you have one handy. On a slightly different related topic, has anyone ever tried su

problem with my 4SQRP Ozark Patrol Radio
Hi Herb, The fact that it squeals seems to indicate the audio section is at least working. Not quite sure why voltages around Q1 are not right, so for some reason the problem seems to gravitate there.

Thanks, Curt. Your audio files sound just like my receiver does on 80 and 75 meters, but only after the addition of the 10 ohm resistor to the one turn feedback coil going through the center of the to

Hi Curt, The most likely thing to do, I think, is to replace (change the value) of c11, a 560 pF capacitor, that is wired to the toggle switch, that is your band switch. I believe with the 560 pF capa

The idea of "forgetting" about things reminds me of the old joke about "old timers disease." It goes like this. "There are three things that indicate you are growing old. The first is a loss of memory
