I have a question about a mod I have been trying to make to my Kenwood
TH-28A. If anyone can help me please reply!

I contacted Kenwood and asked them how I could get my TH-28A to allow me to
transmit in the 155.000 range. I am a local police officer and would like to
use my own radio on duty because the portable radios we carry are horrible,
and our town refuses to buy us a repeater. I know my Kenwood has better
range than the ones we are issued at work.

I have read about the same mod from several different locations. It says to
remove diodes D8 and D10 and install one of them in D14. I have done this
and it opens up some new frequencies in the 340.000 range for Rx. That is
only one of the supposed outcomes of this mod. The mod is also supposed to
open up extended Rx/Tx from 136.000 to 178.000. I need to transmit on
155.070 but the radio still will not let me.

Has anyone had any luck with this mod? Or know of a different way I could
get my desired result? Any help would be much appreciated.
