[Motorola] Mitrek Mods

[motorola@mailman.qth.net]

I built a UHF rptr using 2 Mitreks.  One normally does the XMT function
and 1 does the RCV function.  Works fine that sway.  Both radios have
the rptr's XMT & RCV frequencies so, if one fails, they can be swapped
simply by swapping coax connections and controller connections and
the rptr's back n the air in a coupe of minutes.  The rptr's been on
the air for 9 years without a single hiccup.

Using a single Mitrek as a rptr doesn't work well, though.
