Thank you Arman for coming back with
solution, something to keep in mind (or somewhere on the
computer).

Hello everyone,
Just for information to all that have the problem. I have found
the source of the problem. It is a faulty relay in a power
amplified board. In my case the relay was the one that switches
RX from GND to antenna for 20m band.
Re-soldering the relay contacts did not help and when listen to
the noise and kick the relay, the noise become attenuated and
come back within a minute or less. It looks like that there are
some internal contact issue in this relay.?
Just ordered from Conrad SY-12W-K relays? to replace them. Also
found same problem on 15m band but this relay is working more
stable, showing the same issue not always. Any case will change
it also.?
