I have three VX-231 UHF radios, two that program up just fine in the Amateur Band, 440.000 -446.990. I now have a third radio, same band etc but it will only program outside the Amateur band. The programming software returns "Frequency Range Mismatched!". Any ideas how to get around this?

I am not aware of any way to ‘change’ the frequency range of the VX231’s.

They are pretty cheap on eBay, unfortunately the G6 band split is pretty rare, much more common to see the G7(450-512MHz) radios.

CE99 open the default ud file and use this https://windows-enabler.en.uptodown.com/windows to change the freq in Hardware from 450 to 440. Save the default. It's read only so disable that first. Read your 3rd radio change it's hardware from 450 to 440. Enter your freqs, save write and you should be good. I don't know how low it will go without retuning. Please reply if this does or does not work as I don't have a 231 in front of me.
