Hi Phil,

One other thing might be that the cable system is leaking as well.
Your friends might want to check out receive on the 2 meter band to
see if they're getting any interferrence from the cable system.  

This could vary, but my experience is that if shielding or whatever
is bad in the cable system you can hear some very strong signals in
the frequency range around 145 to 145.5 MHz.   

But, it might be worth checking out the entire 2 meter band to see
if leakage from the cable system is interferring with 2 meter
reception.


I had a problem when I lived in the bay area where I was causing
some interference to people using cable and I found I also had some
really bad cable interferrence around 145.25 or so.  I finally got
the cable company to fix the leakage problem after reporting them
to the FCC, and then my interferrence to the system also
miraculously disappeared.
