NFM. Antenna cannot be detachable for GMRS radios.

Do FRS/GMRS radios use wfm, nfm, or other scannable, non-digital modulation
modes?
All I can find on the fcc site is power level restrictions and whether or
not you can have a detachable antenna.

That's not true. I have a pair of these that have detachable antennas:

I suspect the regulation is that a radio that is FRS only cannot have a
detachable antenna, though I'm not sure. Nevertheless, I know there are
GMRS radios with detachable antennas.

For GMRS and FRS rules, see:
http://wireless.fcc.gov/services/per...generalmobile/

"If you operate a radio that has been approved exclusively under the
rules that apply to FRS, you are not required to have a license. FRS
radios have a maximum power of =BD watt (500 milliwatt) effective
radiated power and integral (non-detachable) antennas. If you operate a
radio under the rules that apply to GMRS, you must have a GMRS license.
GMRS radios generally transmit at higher power levels (1 to 5 watts is
typical) and may have detachable antennas. The current fee for a new
GMRS license is $80."
