Can I reprogram the GXT1050 GMRS frequencies to PMR frequencies?

No. The T5603 is a version of the TalkAbout made for use outside the USA, and has preprogrammed frequencies (possibly PMR frequencies for the UK) which differ from the FRS/GMRS frequencies in the T5500 made for use in the USA.

Best regards.

Sorry, these two types of radios are not compatible. PMR operates in the 446 MHz range, and GMRS/FRS are in the 462-468 MHz range.

Best regards.

The two radios share no frequencies in common. The T5720 has the US frequencies classified as FRS and GMRS, between 462-467 MHz. The T5422 has the UK frequencies classified as PMR and dPMR which are in the 446 MHz range.

A list of UK frequencies can be found in this forum: http://www.transmission1.co.uk/forum/viewtopic.php?f=4&t=23400

Hi Kate,

The short answer to your question is: no, or "not readily". Here's why:

The Motorola 4900 radio operates in the FRS (family radio service) and GMRS (general mobile radio service) in the UHF band. This radio will work with any other FRS / GMRS band radios (no reprogramming of transmit and or receive frequencies is possible for these radios). The trick is that the numbering of the channels may differ from brand to brand ie: Ch1 on your Motorola may not necessarily be Ch1 on a Midland radio or other brand. A complete list of the frequencies and channel assignments for FRS /GMRS can be found on Pg. 17 of the manual. It is important to note that without a valid GMRS license, you are prohibited from transmitting on the GMRS only channels (Ch 15 through Ch 22). The combination GMRS/FRS channels (Ch1 through Ch7) and the FRS only channels (Ch8 through Ch14) are for individuals and family members that do not have valid GMRS licenses. If this is you, you should limit your transmissions to Ch1 through Ch14 only, as FRS does not require a license in the US. Unlicensed use of GMRS only Ch15 through Ch22 can result in fines and imprisonment if caught by the FCC.

Further complicating the issue are the so called "privacy tones". This is simply a very low or "sub-audible" frequency that is sent whenever transmitting. Motorola calls these "Interference Eliminator Codes". When another radio receiver is set to listen for a particular privacy tone, it stays silent until a transmission with the exact same privacy tone is detected. Again, these tones are listed in no particular order, but are generally listed as 1, 2, 3, etc. or a, b, c, etc. instead of the actual frequency in hertz. You can selectively set your radio to transmit & receive one of the 38 codes or, set the code to "0" to communicate with radio that do not offer these privacy codes - or does not use the same frequencies for these codes. You can read more on Motorola's codes on Pg. 19 of the manual.

The Motorola CP200 radio on the other hand is a commercial radio, and requires computer programming with Motorola software. The CP200 is offered as both Low & High sub-banded VHF and Low, Mid & High sub-banded UHF radios. You would need to have a CP200 that is designed to accept the Mid UHF band (438Mhz - 470Mhz) frequencies in order to program the 462Mhz & 467Mhz FRS / GMRS frequencies into it. The final obstacle would be what is called "FCC Type Acceptance". The CP200 is probably NOT Type Accepted for transmitting FRS/GMRS frequencies, and as such the Motorola dealer doing the programing might balk at putting them in. You can read a spec sheet on the CP200 here.

I hope this helps & good luck!

Your GP338 would need to be reprogrammed to one or more of the frequencies available in the T5720. If you are using the interference code eliminator, it would also need to be programmed into the GP338. Take your GP338 to your local Motorola dealer for reprogramming.

Here is a link to the user guide for the T5720, where you will find a list of frequencies: http://www.giantintl.com/RadioPDFs/Outdated%20Manuals/T56XX_57XX_User_Manual_E.pdf See page 19.

No, unfortunately there is nothing you can do to change the 462-467 MHz radio to do the PMR 420-450 MHz which is legal in the UK.

Here is some info concerning PMR446: http://en.wikipedia.org/wiki/PMR446

A 22 channel transceiver is an American system call FRS/GMRS radios which are actually illegal in the UK and rest of europe. They use different frequencies completely and will not work together on you other PMR radios.

Hello codeencrypt,

THE SP100G is essentially the same radio as the SP100U UHF business band unit that Maxon made at the same time, just pre-programmed for GMRS. I believe there is a programming kit for this radio (Model number: SPK400C) which may still be available for purchase from Maxon directly. Otherwise, your best bet is going to be contacting your local Maxon dealer to see if they have the capability to program he radio.

Best regards,
Ken

Hi,

Yes, but depends on the configuration/setup and programming/frequency assignation of the MTS2000.

To my knowledge, the UHF version of the Motorola MTS2000 are designed to operate either in the 403~470Mhz or the 450~512 or 520MHz band.

On the other hand, Motorola TalkAbout Radio are design limited to operate in the FRS band which is 462.5625~462.7250MHZ and/or the GMRS band which is 462.550~467.725.

So technically, both the MTS2000 and the FRS/GMRS share some frequencies. What needs to be done is to re-program the frequency allocation of the MTS2000 into its channels to match the TalkAbouts frequencies. The other way around is not possible. TalkAbouts frequency assignments can not be reprogrammed/changed. Below are typical TalkAbout Channels/Frequencies.

Hope this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
