How can I find the bandwith of my radios frequency?

[ASTRO_Man]

I have a Motorola Radius SP50 using 151.775 MHz and DPL: 244.

I am programming a Motorola RDV2020 with the same info and I need the bandwidth of the frequency that my radios use. It's either 25 or 12.5 KHz, I don't know which one?

SP50's are not NB capable, so it would be 25k. plan on replacing it next year as it will be illegal to operate on Part 90 freqs. i have not looked up the freq you listed to see if it is FRS/MURS or part 90, if FRS/MURS then you will be ok to continue using it.

The SP50's were sold as EITHER wide or narrow band radios - not programable
The only quick way to tell is by looking at the entire model number

A typical model number would be P93YQT20G2AA - the "20" after the YQT indicates 25KHz .

P93YQT00G2AA would be 12.5 Khz spacing. - the "00" after the T indicates 12.5 Khz

Probably 25KHz - 98% of the one I have seen are wide band, although they are around

Is 151.775 MHz Part 90 or FRS/MURS? Is there a list to check-out? What should I do if it is Part 90? Can my camp get a license?

151.775 is Part 90
