19-07-1998 Extended
frequency TR-2600A
Here is some info on the kenwood model
tr-2600a handie - talkie....
If you want to be able to transmit on the
extended freq area then do the following mod....
- Remove the front cover of the radio
- Locate the ic chip in the lower right hand corner.
- Find the 2 diodes number d32 and d33 (they should be the top two on the
right side of the ic chip, also they have ben cut beforenand (re-soldered)
- Un-solder the two diodes (breaking their connection).
- Replace the front ctver.
- Re-install the battery and turn the unit on, then push the reset button on
the back.
The tr-2600a should now be reprogramed and it should also
transmit anywhere it will recieve...
I forgot to add that d32 and d33 on
the recieve board (but that is what is under the front cover).
