C'mon Gene, try to make some sense here will you?...why should
one tune to 60 Hz? (the power line freq btw). Pls do explain what
the hell you're talking about.

The power line frequency (after BPL) will include the frequencies
2 to 80 MHz and the harmonics. I was just using 60 Hz a poor example.

WWV time signals will be wiped-out. NDB navigation sites will be
wiped out. Etc, etc. The noise floor in the 2-60 MHz band will be
significantly higher than it is now, thus requiring higher power, or a
change in operating frequency.
