Just received my new rig, neither the supplier nor Kenwood had the mods available to date.

1. Remove the bottom cover, 5 screws (not the speaker side).
2. Locate and remove "W601" (chip resistor) and "W602" (green wire). They are located within 2 inches 
   of the optional VS-3 voice synthesizer board.
3. Reassemble radio and after power-up, press the reset switch on the front of radio.

Here is your new TRANSMIT range

136.000 - 174.995

400.000 - 469.995

This is the RECEIVE range (mode selected).

118.000 -  135.995

136.000 -  199.995

200.000 -  299.995

To modify the transmitter to cover 142 - 151.995 Mhz and 420-449.995 Mhz, perform the following steps:

1. MOST IMPORTANT - this mod will do a reset on your radio and erase ALL of your settings
   (memory, APRS, menus, etc.). Use the computer program to pull all of the settings out BEFORE you go
    any further. Or if no computer, a very large tablet. This radio has many programmable features.
2. Turn off the radio and disconnect the power
3. Remove the five screws from bottom cover (not the side with the speaker).
4. Remove the bottom cover. It may take a little prying with a small screwdriver.
   
   REMEMBER if you haven't saved your settings, all will be lost if you proceed beyond this point.
5. Cut ONLY the famous Kenwood green wire, located near the voice synthesizer board connector.
   The green wire ties two PC board lands together and is about 1/2" long. Make sure the ends can't short
   against anything.
6. Reinstall the bottom cover.
7. Reapply power and turn the radio on (it will automatically reset).
