[Elecraft] K3 K144XV spurious signal on 144,414.1

[Fausto Coletti]

If you put a 144 MHz prtable receiver close to the K3 you can listen this 
spurious
and also some other weaker spurious (S2-S3).
If you disconnect the supply at the K144XV the spurious do not disappear.
It is a lot that I'm investigating the origin of these spurious but I have 
not found where
they come from.
