Until such time as someone can accurately measure the effect of height (and obstructions) on a Part 15-compliant system, this will obviously remain an...

Actually, you weren't merely doing that. You attempted to bring power (which I never mentioned) into the equation to obfuscate the situation. The NE...

Agreed, Carl. Rich Fry is quite adept at ignoring arguments that don't conform to his beliefs. He has no experience in actual use of Part 15 AM and ...

It seems to me that it would be easier to attempt to duplicate the effects of obstructions on a Part 15 signal with a field strength meter, rather tha...

Yes, SWR affects range. SWR is a measure of the ratio between reflected power (back through the antenna, feedline, etc. due to mismatches) and forwar...

Carl states it best. The assumption that all other things are equal between a Part 15 installation and a licensed station is not correct. Otherwise,...

I can only go by my experience, regardless of theory. When I raised my wire antenna so that it was above my roofline, range increased substantially. ...

I can't comment on the effect of obstructions on licensed radio station signals. But I can comment on that effect for Part 15 signals. I also have o...

This last post is a classic example of misinformation wrapped in a bunch of other stuff. I don't know where you're getting the factoid that 2 miles r...

When i was referring to a quality compromised radio signal, I was really talking about Part 15 AM. When I was running my Rangemaster, and getting wel...

When I was on Bowen Island, I ran Artisan Radio as a community radio station (under BETS-1 FM rules). We were located in a storefront, located in an...

Most legal over-the-air Part 15 stations will get very poor range (measured in the hundreds of feet) on ordinary receivers. That includes both AM in ...

I suspect that basically the same language 'tolerance' is applied in both the U.S. and Canada. The CRTC, the regulatory body responsible for content ...

Broadcasters in Canada require BOTH an Industry Canada and CRTC license. If you follow BETS or RSS211, you are exempt from those licenses. But notwith...

Actually, both BETS and Part 15 state that we are tolerated. Stations operating under these rules can be shut down at any time.
