Well the verdict is in!!!
Just hooked up sensor loop to the spectrum analyzer and started to sniff
around the shack.
WOW no other words can describe the noise coming out of the cable modem
-50dbm starting from 50Khz and doesn't drop until I hit about 45 MHz above
this freq. it's about -105dbm
If Comcast wasn't coming out tomorrow with a new modem I'd be hacking the
end off this sticking power supply this minute.

p.s. If anyone would like I can try and take a few digital pic's ....
BTW Look out if you have a Motorola Cybersurfer modem in your home.
