I now have U-verse installed. Out of the box 10 watts on 40-160 blew away the 
modem. There was a lot of noise on the phones, installer didn't put in any 
phone filters. 6-20 meters doesn't seem to be a problem.

There is a VDSL splitter at the box coming into the house. I put a DSL filter 
at the splitter before the run to all the house phones and a 0.33 ufd capacitor 
across the house phone lines. No more noise on the phones.
As a bonus, there is no more RFI on the phones when I tranmit.

600 watts out on all bands 160-10 except 80 meters over about 20 watts the 
modem works fine with no drop out. Not toroids, modem not grounded to TV 
converter box etc.

With my 50 uamp RF sniffer I can see a lot of RF on the coax from the splitter 
to the modem and very little on the AC lines.

My question is what core material should I use to install the big binocular 
type chokes on the coax and how do you wind them? There must be a link to the 
info, but I can't find it.

I had two cores of unknow material and wound about 12 turns thru them. I don't 
see and difference in RF levels on either side with my sniffer ?
