If I may ask a constructive question...
Why would you choose to (if legal) use digital voice modes on MURS or FRS? Where does analog fail that digital would be superior?
Here is the answer from the Rule Book
MURS is the only un-licensed service other then 900 MHz ISM that allows for Digital Modes, but not Digital Voice.
95.631
(e) No GMRS or CB transmitter shall employ a digital modulation or emission.
(j) A MURS transmitter must transmit only emission types A1D, A2B, A2D, A3E, F2B, F1D, F2D, F3E, G3E. Emission types A3E, F3E and G3E include selective calling or tone-operated squelch tones to establish or continue voice communications. MURS transmitters are prohibited from transmitting in the continuous carrier mode.
This would include
8K10F1D - P25 Phase I C4FM data
8K30F1D - NXDN 12.5 Data
4k00F1D - NXDN 6.25 Data
Technically DMR would not be allowed on MURS since it's emission code doe not fall under those listed in part 95.631.
7K60FXD - 2-slot DMR (Motorola MOTOTRBO) TDMA data
7K60FXE - 2-slot DMR (Motorola MOTOTRBO) TDMA voice
