P3 - spikes that never move

[Bill Clarke]

I have spikes (low intensity and wide) that do not move when the K3 is
tuned across the band. I assume they are internally generated, else they
would be tunable. Nothing should be displayed except actual RF signals
that can be tuned to.

They are not a big deal, but it is disappointing to see them on such an
expensive device. Am I the only user seeing these?

As always, reply only to the reflector - to allow others to learn also.

Thanks,

Bill W2BLC

I'm sure this very question was asked only a few days ago - so, no you are
not the only one. Generally these seem to be at a very low level and are
often obscured by band noise - that will depend on the characteristics of
your location and aerial. The problem will be most clearly observed if you
have a low noise qth.

 

I found out about them when I used the K3/P3 combination with a 2m
transverter.

Bill,

If this is the same thing we were talking about a few days ago, I was
able to pretty much eliminate mine by replacing the BNC cable for the IF
input.

I'm in Fixed Tune and Fix Track mode on my P3 and when I tune the K3 the
spikes would move with my display. You could never catch up to them or
hear them in the band pass. Annoying, but not a major deal. But like I
said, a few of us found the BNC cable at fault and I think one op
mentioned sanding the cabinet ground areas of the P3 to improve
connectivity and this helped as well.

HTH
