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.

Mark,
I would first check the current draw, which should be around 170-180 ma in RX. And there is always the old trick of hooking it up backwards. Been there, done that. ;) If that is good, then look at the coax cables.

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