That signal is the picture carrier for a cable TV channel (#18, as I 
recall) and  is the most common symptom of a bad connection in one of 
the coax cables that carries the the cable TV signal.  And the most 
common cause of that is a poorly installed F-connector (the crimp 
connector used for TV coax in receiving systems).  Although cable TV 
installers make their share of mistakes, a more common culprit is a home 
owner trying to cheat the system and install their own .

A good way to find the bad connection(s) (and there can be more than 
one) is to grab your 2M talkie, tune it 145.25, and look for where the 
signal is strongest. Fix those bad connections and most of the other 
trash leaking from the CATV system should go away.
