For M2, you do not need a PTT interlocking device if you use two radios.
If you use two radios per band, then you need a PTT interlock for those two
radios on each band.
If you use a third radio for 3rd band multipliers, you need an interlock.
This 3rd band interlock can be complex, depending on how you want to
operate.
But, for a M2 station with just two radios, one for a band at a time, you
do not need an interlock.
