To give the TM321 tx coverage from (142 0r 143, don't remember which) to
151.995 mhz, remove the top cover. Look for a loop of wire comming from the
display area (the board with the CPU) and going right back. Cutting this wire
and then doing a CPU reset is all you need to do. Takes about 2 minutes.
Be sure that the ends of the wire don't short to something.
