QRM for Internet
 

Hello dear all !

I am using R-7000 vertical located on the roof of 9-store building.
I was happy to notice the absence of any QRM for both radio and TV broadcasting with my new 1 KW amplifier.

But there is the only problem with neighbor from the last floor - he can hear some SSB transmission in his phone and
It slows down or even breaks the dial up connection to Internet.

Are there any links for ready or homebrew RF filter for "last mile" of phone line?
Any suggestion for this case?

Is it possible to ovecome this problem at all ?

Regards,

Hi, Igor,

Have you tried ferrite beads on his phone line. There are large ones that clip
around any small line (like a telephone line). If the RF is coming in because
the phone line is acting as an antenna, this might do the trick.

Good luck,

These filters work exceptionally well:
