Just assembled P3 a few days ago. Having a problem that I can't seem to solve.
Background: Haven't done K3 OUT mod yet (SN 113 ---- fairly old) ... really am apprehensive about opening up K3 again ... but I know I'm just being neurotic ... will face any weekend now). The P3 was pretty much performing as expected ... given that I haven't done the above mode yet, and I live in manhattan with a mediocre hamstick hung outside my window .. I could generally see strongest stations above a lot of noise on P3. That was good. But over past few days, it seems that the sensitivity of the device was diminishing .. started to have trouble seeing the few stations that I could actually hear above the noise on my K3 ... and then today, it now appears that the P3 is basically deaf to the K3 ... I see some low ampitude noise, which doesn't vary in appearance with or without the coax cable to the IF OUT of the K3 plugged in. I am listening to a fairly strong Italian CW station now on 20 meters now, sticking his head above the omnipresent S5-6 noise ... armchair copy, if you will, but all I see is noise at the bottom of the P3 screen. The center frequency tracks my K3 nicely ... but no matter how I adjust the REF, SCALE and SPAN, all I see is noise. Any thoughts would be welcome. Yes, I will dive in and do the IF OUT mod, but am trying to understand the curious behavior, and to see if it sounds familiar to anyone. Thanks in advance -- WB2SSB Joseph J.
