It's either a poor connection or some one has wired their antenna direct 
to the set along with the cable without an AB switch.  If you operate on 
the calling frequency for a while and the leak is local some one is 
bound to complain, particularly on the History Channel.  Must still be 
running analog in that area.

Their channel line up varies with time and company.  Switch to 145.25 
and they'll probably be a lot stronger. Not the same channel though.

BTW Normally if you can hear them they can hear you.  I did a 
demonstration some years back (not in this town) where I was hearing 
lots of places in the town where I was living at the time. I went into 
the cable office and head end.  Explained the many leaks around town and 
that if they were getting out mobiles would be getting in. They couldn't 
believe it so... I demonstrated in the office with low power, then 5W, 
then went out to the car and fired up 50W.  They came flying out of the 
office waving their arms to stop.  I explained there were many hams with 
50 W mobiles around town and that happened every time one drove by or 
under one of those leaks.  I had proven to them that I could wipe out 
the entire cable service for the entire town with a 5W HT and that a 50 
W mobile was a disaster for them.  The next day the bad leaks were 
already cleaned up. In two days I couldn't find a leak and they wanted 
to know as soon as any of us ran across one in the future.

Every once in a while I switch to 145.25 to check for leaks.

Good Luck. es 73
