[Elecraft] K3 K144XV spurious signal on 144,414.1

[Sverre Holm (LA3ZA)]

Good to hear that others are hearing it as well, so then it is for sure
nothing that radiates in our shack. I've heard of two now, at 144,411.09 MHz
and 144,414.8 MHz respectively.

What we found at our club station's K3 was:
- it cannot be heard on the 28 MHz band which is where the 2m band is
downmixed to, on 28,414.1 in our case
- the signal goes through the first mixer as its pitch will change (a lot)
if the 116 MHz crystal in the K144XV is subjected to a coolant spray
