Two thoughts come burbling to the top...
Try adding an attenuator inline (it can be at any convenient point in the line given your current setup.
I'd try between 10 & 20 dB. Here's one example:

Idea #2: Did you bring an appliance, tool or some electronic devise with you in the move that generates interference? Turn off all power to one suspect device at a time to isolate the culprit.
Patience is often learned though being forced to wait, take you time, or otherwise deal with a nearly intolerable situation... (No extra charge for the half baked wisdom
)
