Other features:
The  following information is based on things I have seen on  the
net and may not necessarily work.  I have also put comments  that
don't fit in the chart in this section.

- Kenwood TH-77A
   2m section is modifiable for MARS/CAP
   can be modified for 118-165MHz Rx
- Icom IC-24AT
   A diode will extend UHF transmit range to 410-485
   A diode will extend VHF transmit range to 138-168
   Keyboard entry can enable 100-1000MHz Receive (diode has to
   be removed on older models).
   A diode can be removed to allow cross-band repeat

Icom IC-32AT
