Good information Rich. Thanks.
As for interference, I believe that the manufacturer numbers are best case. Selectivity (rejection of adjacent channel interference) is definitely a factor that has to be taken into consideration, particularly in crowded band conditions.
Mono signals will definitely get the most range. Even if you broadcast in stereo, the range in which you can actually receive in stereo is limited, given the factor of about 10 in sensitivity that these high end home and car receivers have. I have no reason to believe that this factor will change with mid range receivers or portables either.
I broadcast up here in Canada in mono (I experimented with stereo and found that it did get less noise-free range, even when you were receiving in mono). I even stream in mono. It maximizes the number of listeners I can have on my stream (I run my own server and pay for the bandwidth). Plus, a lot of my programming is in mono, and isn’t all that affected even if the source material is in stereo (right now the programming consists of 50s and 60s obscure teenage-oriented pop music – ‘The Best Music You’ve Probably Never Heard’ as my slogan goes).
