Depending on the type of FOB, yes, there should be no problem. The
URI and RIM work fine with the (large) amount of audio from the
VOL/SQ HI. If using a modified or converted USB audio adapter, just
make sure the audio is sufficiently reduced so the MIC input isn't
over-driven.<br>

Remember, for transmit, you need to feed it SEPARATE "program
audio" and CTCSS<br>
(you will need to use BOTH outputs of the USB device
separately).<br>

Not to argue with the MASTR II Guru, whom ever that may be, but
composite works fine on MASTR II's that have the FM ICOM - - feeding
the modulation pin directly. Yes, this requires pre-emphasis and
limiting turned on in the software. <br>
<br>
If the M2 is a phase modulated type, then yes, use separate audio
and CTCSS outputs from the radio interface thingy. Feed the MIC HI
with the voice audio and the Channel Guard input with the CTCSS
audio.<br>
