Ok here is the deal. At my brother house we have installed a base set
up. We have a mobile radio hooked up to an antron 99. The antron is in
the attic on the 3rd floor of the house mounted in a 22ft tall section
of the attic. The SWR is below 1.5 on all channels. everything is
stock. only one TV in the house is getting audio only interference
nothing else is getting any interference. This is clear as day when
ever you TX.

This happens with the TV muted or unmuted for that matter and even with
the coax unplugged from the back of the TV.

I just bought a B&W TVI filter off ebay in hopes that it might help. Do
you think it will? What else can we do? Please help...

thanks
Jim
