As an frequent reader, and infrequent contributor, I am most interested in the back and forth postings about AM & FM signals - on their various frequencies and ERP outputs. I also enjoy reading about DX'ing. I used to collect QSL cards myself.

Saying that, I'd like to have a better understanding of this subject and would appreciate any response to my question - "what is the best, or are best, site/sites that I could I link-to learn more?

I do know one thing.  If you're told not to turn the big knob, that if you do there will be dire consequences.



Thanks for any feedback.

Cheers!
