• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

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.
