[Elecraft] Fw: K3 Weird Intermittent Problem

[Paul Antos]

I have an old timer ( #129 ) w/o the new synth boards. Strong noise at 7033 thru 7033.5 , and a much weaker version around 7021 thru 7022. Whatever they are, the weaker one disappears when the ANT jack/coax is shorted, and both disappear when nothing is attached to ANT. I had always considered these to be some wascally wall wart someplace.

Subject: [Elecraft] K3 Weird Intermittent Problem

I was on 40 meter CW Saturday afternoon operating the Indiana QSO Party
mildly, using a low 40 meter dipole and an amp.  This K3 is new to me serial
#8600 range and was on the K1N expedition.  My other (2nd)  K3 is in  #4600
range.  Two times I experienced a broad noise from 7024 to 7033 tuning above
or below this range and the noise disappeared (I did this several times to
confirm).  It sounded like a SSB station splattering.  I had a P3 on and saw
it also.  The 2nd time it happened I had my other K3 on and swapped
frequencies and radios and the noise was not on the 2nd K3, swapping back
and it was on the 1st one again.  This was the first time I have experienced
this but I have only had the new K3 in line for about a week.  I used the
radio maybe 4 times in the last week and did not notice any problem.  I used
the radio the rest of the day and did not notice this behavior again.

 

Any thoughts?

 

Thanks,
