Ed and I tested range of his IBEC design with more than 15 radios of various ages, all the potential modulations, on all frequency bands including the old ham freq (1 radio as I recall). AM modulation was about the only type that might be a problem.
All radios on 72MHz-FM, 72MHz-PCM and Freq Hop 2.4 lost practically no range. Ed designed in noise filters for that specific reason.
There will always be naysayers and that's fine with me. I simply choose to test first and see for myself. Heck that's what I did with gas engines too since so little info was trustworthy.
Same here. The problem I see is, you and I have the confidence and experience to trust our test results and proceed. Somebody just getting their feet wet, might not have the same degree of confidence or experience, thus may not be able to bring themselves to proceed. They freeze, like a deer in your headlights?
