With the start of the 160 season I was working on my RX antenna. Could not null a hash that turns out to be coming from my DSL modem. D-Link 2320 with a lot of ferrite and a lot of turns on both the phone line and power cord.I solved the problem of the TX blowing away the modem with all the ferrite.

Noise is S-4 with modem unplugged and S-9 at 40khz wide peaks with modem plugged into wall. Same regardless of plug polarity or outlet I use. Noise is there with telephone line and link to router unplugged.

Trendnet router is also noisy, about an S-unit add with power plugged in.

Any thoughts, cures, try this ideas?

Thanks
