Hi Mark, WD4ELG
First of all see if the noise level increases when you power supply your preamplifier.

Was working before the QTH relo. Reinstalled in the attic. The 144
preamp,
same power supply, working just fine.
Any ideas on how to check w/o taking it apart? The connectors have not
been
modified.
As always, I am certain it is something simple.
