TM721A.9
While you have your radio open, you may want to activate the cross-band
repeater function. Lay the CPU board down so the two ribbon cables come off
to the north. A little northeast of the lithium cell, just east of the bare
copper landing at the top of the board is chip resistor R121. Carefully
remove it (you will probably break it). Now, you can put your radio in the
cross-band repeater mode by hitting "f" "ABC". The mode is indicated by three
decimal points in both main and subband frequency readouts and a signal heard
on either band is retransmitted on the other. A three minute timer is in
effect, which may be turned off by removing R122 (not tested). Return to
normal operation by again hitting "f" "ABC". During repeater operation, all
other functions are locked out. Of course, the TM-721A does not auto-
identify, so it must be under direct operator control.
