K6DSP; conditions unsettled
I worked Mike K6DSP in San Diego on 20M PSK31. First his signal was fine, then very wide, and then he reduced drive and it was OK again. Then mine started having problem -- garbled, and then unsteady, and he couldn't copy me. I took my PSK-20 and HFPacker Amp off the antenna and put it on the dummy load. Maybe I had the audio gain misadjusted down and the VOX was cutting out... anyway, I have the PSKMeter hooked in now, on the QRO setting, but I am not getting reliable readings for IMD when the amplifier is on. I don't know if it's the A/D in the PIC or if I truly am having trouble with the amplifier.
