Negative. GMRS regulations forbid this type of communication. Data
communication is forbidden by regulation. The *only* exception is a
waiver granted Garmin for its GPS/GMRS units.
GMRS regulations forbid any non voice communication See sections (e)
and (f) below::
------------------------------------------------------------------------------
Sec. 95.631 Emission types.
(a) A GMRS transmitter must transmit only emission types A1D, F1D,
G1D, H1D, J1D, R1D, A3E, F3E, G3E, H3E, J3E or R3E. A non-voice
emission
is limited to selective calling or tone-operated squelch tones to
establish or continue voice communications. See Sec. 95.181 (g) and
(h).
(b) An R/C transmitter may transmit any appropriate non-voice
emission which meets the emission limitations of Sec. 95.633.
(c) A CB transmitter may transmit only emission types A1D, H1D,
J1D,
R1D, A3E, H3E, J3E, R3E. A non-voice emission is limited to selective
calling or tone-operated squelch tones to establish or continue voice
communications. See Sec. 95.412 (b) and (c).
(d) An FRS unit may transmit only emission type F3E or F2D. A non-
voice emission is limited to selective calling or tone-operated squelch
tones
to establish or continue voice communications, digital data
transmission
of location information or text messaging.
(e) No GMRS or CB transmitter shall employ a digital modulation or
emission.
(f) No GMRS, CB or R/C transmitter shall transmit non-voice data.
