While the house is probably "grandfathered" from complying with current 
Electrical Code, you should definitely check out the grounding and 
bonding of your home and station. At a minimum, you should have 
everything in your station bonded, have a decent collection of driven 
rods all bonded together, to all other grounds (telco, power entry, 
Comcast).

That said, it's Comcast's problem to clean up their equipment and cable 
installation. Common causes of issues like this are poor coax connectors 
and installation, both those done by Comcast and those done by a 
customer's illegal "tap-off." Another likely cause is a Pin One-like 
Problem where coax cables connect to their victim electronics. If 
possible at this time, I'd try to get ARRL involved.
