K3 problem

[David F. Reed-2]

  My K3 (serial number 1476) was working fine this morning, but started
exhibiting a problem this afternoon...

I occasionally get a "ERR PL1" message on the screen; I have the
following behavior:

   1. other stations report my transmission is off frequency or garbled.
   2. sometimes the receive acts like there is no antenna connected
      (Noise floor at -140 db, as opposed to the more normal -120 db on
      40 meters)
   3. Sometimes the TUNE produces 0 watts out (set to 100); other times
      it gives the full 100.

I suspect all these symptoms are related to the error message.

I note that the rig is warm (on for a few hours) but not hot; I don't
know if it will do this from cold, but I will try to find that out (rig
is off now waiting to cool down to about 80 deg. F.).

Any thoughts or suggestions?

Thanks and 73 de Dave, W5SV

  David,
Have you followed the steps in the manual for this error?  If not, do
that first - let the K3 warm up before doing this calibration..
If it persists, try doing the Reference Oscillator calibration (use
method 2).

73,

One of the K3 mods for the synth board was supposed to fix this....
Did you get your K3 before this mod was put in place:
