Frequency range what is the frequency range of the T5720 Talkabout

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

In glancing at the frequency charts, it does not appear the two have any frequencies in common. You can look for yourself at the follow links:

In the USA the TalkAbout radios operate on FRS (family radio service) frequencies which do not require a license. Not certain of the laws in other countries.

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a link to the user guide for the T5720, where you will find a list of frequencies: http://www.giantintl.com/RadioPDFs/Outdated%20Manuals/T56XX_57XX_User_Manual_E.pdf See page 19.

Unfortunately the T5728 is not compatible with the US FRS (family radio service) frequencies. The T5728 operates between 409-410MHz. The FRS radios operate between 460-470 MHz. FRS frequencies are license-free frequencies for use in the US, as regulated by the FCC. Other countries have differing rules and thus their frequencies assigned to family usage differ. Best regards, and sorry we could not help.

Program the frequency, code and Qt filter (if any) to match one another. For simple operation set the code and Qt filter to off (zero).

The frequency range and operatngmode of the two radios are compatible. To get the Radius operating on a GMRS channel you'll need a Motorola programming cable and software, OR a trip to a Motorola dealer for frequency programming. Considering the cost involved, the 2-watt output of the Radius, and the 1-watt output of the Talkabout, you would be better off performance and cost wise buying a pair of 5-watt GMRS portables.

No, they have no frequencies in common. The TLKR-T3 uses the PMR446 frequencies common in Europe. The T5720 uses FRS freqeuncies common in the USA.

Set both the frequency and the interference eliminator code to match one another. (The big number and the small number) Here is a link to the owners manual: http://www.motorola.com/mdirect/manuals/T56XX_57XX_User%20_Manual_E.pdf

Basic instructions:
Press the Menu Button
The freq number will flash
Use the + or - button to select the frequency.
Press the PTT button to save the channel setting.

To set the code:
Press the menu button until the code starts to flash (the small number)
Press the + or - to select the code.
Press the PTT to save the code setting.

Once you have both radios matching on frequency and code, they should communicate together.

Hello Ruaal,

The frequencies in the TalkAbout T5720 are not adjustable. The radio operates on the designated Family Radio Service channels located at 462 and 467 MHz. There is no way to change these channels to be at 463 and 464 MHz.

Best regards,
