[DX] ARRL BPL Video

[Dave Shrader]

Hi Chip,

It's nice to know that you are still actively reading the various groups.

I would like to hear your thoughts, not on BPL interfering with HF/VHF 
reception, but to the susceptibility of the BPL system and BPL users to 
undesired reception of HF signals that emanate from my or your HF/VHF 
radio. I run 1 KW on HF. When I point my beam at the local power lines 
and have a Rag Chew or spend an hour chasing a DX pile what's going to 
happen to my BPL using neighbor's internet connection?

73,

Deacon Dave, W1MCE
