Ken You are probably receiving W1AW on the image frequency. The default IF frequency is 11.025 KHz which puts the image of 14.047 at 14.069050 MHz. You can adjust the image rejection under PowerSDRsetup DSP Image rejection RX. This is better done with as signal generator and for best results will need adjusting on each band each time a band change is made.

Dear Flex-nuts, I am trying to copy EA9 and CJ7 on 14.070.500 and I hear the CW practice from W1AW scretching in the noise below the PSK sigs. W1AW is at about -80db on 14.047.500 and this is scratching is copyable from W1AW fundamental all the way up through 14.100. Is it some peculiar propagation? or something inside my SDR-1000? Settings: Preamp HI,MED,LOW same, Preamp OFF to a lesser degree, but still there, AGC SLOW, NB on/off no diff, 2.6Khz standard filter (same with Bills new filters), USB, 20M. 2.4Ghz Celeron, 1GB RAM, 1.3.4 stock, M-Audio Delta-44, Loop or HexBeam same.
