IS this correct for the VX-7R: Yaesu VX-7 R (VX 7 R VX7R) transceivers mods reviews software and diagrams


Remove the battery pack.


Remove the sticker/cover seal for the pressure sensing unit (SU-1), in the battery compartment. This is the black strip above cellular warning label and is where the SU-1 option goes.


1 Locate row of eight jumpers. They are numbered.


2 For Mars/Cap, remove solder jumper 5.


3 For Freeband, remove solder jumper 4 and 5.


4 Reset microprocessor. (Press and hold in the 4, band, and v/m keys while turning the radio on.


5 ENJOY

TX Frequencies:
Freeband: 40-224.995Mhz and 300-579.995Mhz
Mars/Cap: 50Mhz-54Mhz, 140Mhz-174Mhz, 222Mhz-225Mhz, and 420Mhz-470Mhz.


I guess there is also a SOFTWARE hack without having to unsolder things on the board?
 

Personally I don't see a benefit at all.

I dont use GMRS/MURS/FRS enough to risk it, thats just me
