TM221A.1

The TM-221A is capable of receiving from 138 to 174 MHz.  With the mod
below, the rig will transmit from 142 to 151.995 MHz.

    1.-  Remove both the  top and bottom cover. Disassemble the front
         panel such that the foil side of control unit (X53-3040-XX)
         is accessable.

    2.-  Locate R25 at the bottom left corner of the control unit.
         Remove R25. You may just want to cut the trace on the left
         side of R25.

    3.-  Reassemble the unit. Preform a microprocessor reset.

I would like to extend transmit to at least 154.995 MHz.  I removed R22
with some interesting results.  First the frequency step changed to
12.5 Hz.  Second the "ON AIR" indicator came on with PTT depression;
however, my watt meter indicated no power on any frequency (including
2 meters).  Any help would be appreciated.
