Make sure the internal cables with the little TNC connectors are all
seated properly. A poor shield connection can contribute to birdies.
Oxidation or vibration could create this condition over time.

I've been monitoring this list for a while, and have gained some
useful insights from the posts. And now I have a question...
I built my K3S #11310 last July, and I added the 100 watt amp and
sub-receiver last December.
A few weeks ago, I started hearing some unusual tones around 14380
KHz and 7259 KHz. The tones are much louder on 14380 than on 7259. At
14380, I hear a lower-pitched tone on 14279.80, and a higher pitched
tone 14279.85. I hear both of these with no antenna connected. On
40m, the tone is quiet enough that the background noise overcomes the
tone. But on 20m, the tones are quite loud. I also hear the tones on
Prior to a few weeks ago, I'm certain these tones were not present. I
saw the thread from 2012 about moving cables around in a K3, but if
there was a build problem, wouldn't these sounds have appeared
immediately? My routers are far away from my shack, and there is no
new equipment in the shack.
