Re: Yaesu betting on C4FM for AR

Low cost DMR radios are probably going to make DMR the dominant mode over time. A little over $100 is all that you need for a basic radio that works. The imports may not be as " ham-sexy" as a high tier Motorola, but they are ideal for experimenting and getting your feet wet in a newer, no...

Re: Wattage output versus tx range ?

Old school thoughts - you need 6db power increase to achieve a 3db signal increase at the receiver. Usually you need at least 6db (4x) power increase to get a noticeable change in received signal quality. Square law... A 3db increase in TX output power, plus a 3 DB gain antenna, plus cleaning up tra...

Re: Narrowband - why does Motorola specs imply deafer radio?

It's been over 30 years since I was in radio engineering classes, but if I recall, if you decrease your FM modulation index by holding you max modulating frequency and decrease your deviation, doesn't that have an adverse effect on SNR? True, your bandwidth decreases, but so does the relative amount...

IMHO, going from a 50 to 110 watt radio in and of itself is not a big improvement as far as improving coverage.
