A few weeks ago, I turned on my K3 and all looked normal except that I could
not hear any signals or band noise on 160M. I recycled the power switch and
heard what sounded like an AM broadcast station, but the tuning knob had no
effect. I could not tune anything. (That was weird!!) Another power switch re
cycle and all worked normally. Last night, it happened again. Same scenario.
This time I had to power down and up about 15 times. Finally, I heard a signal
which sounded like an AM program, but it could not be tuned. The next power on
attempt provided proper operation. When the K3 was not hearing, it also would
not transmit. The keying LED lit, but no power output was seen.
K3 is #1504 and it has new synthesizers (2) in it. I also recently replaced
the connector pins to the 100 watt amp, but I think that the first episode
happened before I had the rig apart to fix the pins. It almost sounds like the
LO is dead when first turned on. There were no error messages, and all looks
OK, except that no signals are heard.
I am going to check a bit deeper. First thing is to look for a proper LO
signal to the receiver. (TMP connectors etc) Any ideas from the gurus?
