MURS has an odd deviation limit on three channels.

---------------
"5.632 MURS transmitter frequencies.

(a) The MURS transmitter channel frequencies are
151.820 MHz,
151.880 MHz
151.940 MHz
154.570 MHz
154.600 MHz.

(b) The authorized bandwidth is 11.25 kHz on frequencies 151.820
MHz,
151.880 MHz and 151.940 MHz. The authorized bandwidth is 20.0 kHz on
frequencies 154.570 and 154.600 MHz.

(c) MURS transmitters must maintain a frequency stability of 5.0
ppm,
or 2.0 ppm if designed to operate with a 6.25 kHz bandwidth.
---------------------------------------------------------------
PRSG Comment: The use of conventional NBFM ("narrowband FM")
transmitters, those having a maximum deviation of +/- 5 KHz, is again
permissible on the two MURS 154 MHz frequencies. On the three MURS 151
MHz frequencies, only the narrower deviation (+/- 2.5 KHz) is now
permitted.
-----------------------------------------------------------------------------
Out units are five channels and have +/-2.5KHz deviaiton on
all 5 channels.

Other then type acceptance, I guess you could clip the magic diode in
an Icom IC28/A/H and turn down the power and use it on two MURS freqs.
