[Kenwood] TM-732 has weird TX offset on UHF

[ken.d.brown at hawaiiantel.net]

Thanks for the responses. I found the information with a google search 
on "radio mods tm-732". The resistors relevant to these options are R19, 
20, 21 & 22 in the control head. It is really easy to get to them. Don't 
even have to remove the radio from a mounting bracket since the changes 
are all in the removable control head. I found mine was configured as 
E5. I changed it to the K4 configuration and it is working fine with the 
desired 5 MHz TX offset on UHF.
