Midland MXT500 how to set specific receive and transmit frequencies with the PC Programming software

[WSDD253]

I am trying to specify a receive frequency of 462.7000 and transmit frequency of 463.2000 on my Midland MXT500 using their PC programming software.

I can specify any receive frequency but the transmit frequencies are only pre-specified via a pull-down list for regular channels, and I can't seem to edit the repeater channel frequencies at all.

I don't believe anyone has edited the firmware to push beyond the GMRS operating band range of the MXT500 radio. In most cases, It would be easier and cheaper just to  acquire a Part 90 radio such as a Kenwood TK880 or TK8180 radio.

463.200 is not a GMRS frequency. The MXT500 is a GMRS radio. Midland is pretty good about abiding by the GMRS frequency requirements. It’s highly unlikely you will be able to transmit on any non-GMRS frequency.

GMRS  frequencies are 462 MHz and 467 MHz so these frequencies I mentioned are withing that range.

Those are not inclusive endpoints to a GMRS band. The only frequencies you are allowed to transmit on with your GMRS license are specified in the regulations:

I'll add to what Steve posted. Here is a link showing the only authorized channels for GMRS.

You can't just pick any frequency between 462 MHz and 467 MHz and use them on GMRS. You have to stick with the designated channels. 

Midland radios will not transmit on anything other than designated GMRS channels. I have yet to see anyone hack a Midland radio.

OK got it - I was using some info from a local radio club but it specified the repeater info incorreclty. Thanks

The original post said you want to find a way to edit the firmware so your MXT500 can transmit on 463.200 Megs and receive on 462.700 Megs as a channel pair. 463.200 is a Business Radio Service freq in the Part 90.35 subpart C in the Business/Industrial Pool. You can not do that legally with that radio and you need a Radio Station Authorization to transmit on 463.200 Megs

They definitely gave you the wrong information. They gave you the offset for VHF repeaters which is 0.600 MHz. And that is why you came up with 463.300 MHz

The correct offset for GMRS is 5.000 MHz which will give you the correct offset frequency of 467.700 MHz.

GMRS repeater channels always use a positive offset of 5 MHz. Your radio will transmit on 467.700 and receive on 462.700. The repeater will transmit on 462.700 and receive on 467.700
