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
