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
Simple mods for RX on 138-168 and 418-458. Tx on those
ranges with a bit more work.
- Yaesu 470
There is a mod for transmit on 140-174
Several people have mentioned that the backlit keyboard is a
nice feature.
