Description

Radtel released Firmware version 2.13c for the new PCB. It expands the AM/FM modulation frequency range to 18MHz-1000MHz. Those frequencies are in fact able to be used.

Saving the frequencies to the radio is possible using the radio itself with the current workaround:
1 - Tune into VFO frequency
2 - Save it to an empty memory channel
3 - Renaming it and correcting its settings with RT-470X programming software.

CHIRP is able to detect the correct frequencies, however editing the channels themselves results in "Out of Frequency Range" error. Editing the frequency in the Radtel software results in the same error.

Can provide an IMG with the frequencies if necessary for testing.

Please, as described in the IssueInstructions you indicated you read, attach a debug log after downloading from the radio and the associated image (please use Help->Report or update a bug).

The radio identifies itself exactly like 2.13A, which makes it impossible to distinguish your radio from those. Are you sure that the "c" revision is the one that added the expanded range?

Radtel's website contains the following changelog for the RT-470X (new PCB):

V2.02 expand air band to 108-137mhz
V2.11A Factory default Firmware (V2.11a 231026)
V2.11A Firmware expand frequency to full band
V2.12A Firmware expand frequency to full band data 20231107
V2.13A Firmware expand full band+8.33khz air band (data 20231213)
V2.13C Firmware compatible with 470X/470/470L( Add AM/FM modulation switch from 18m-1000mhz (data 20240425)

I've only tested with firmware version V2.13C which is what I have installed in my radio and the one I used to download/save the image attached.

Can do other testing if necessary.

Okay, so this is firmware version, not PCB version, I see.

So, first, here's a module you can load via LoadingTestModules to try. So please confirm that does what you want.

However, if you could, is it possible to load the previous firmware into your radio and then see what happens when you put a memory into it (via chirp) that is outside the original range (which looks like it starts at 100MHz)? The concern here is that if people have a radio with the older radio and use CHIRP to put something like 26MHz, we need to make sure that's not going to be majorly problematic.

Can confirm the module works. Will test with previous firmware versions, any specific one you'd prefer me to try?

I think that V2.13A would be good enough. Thanks very much!

These frequencies seem to be available even on v2.11A (supposedly factory default for new PCB), unsure if they work or are just selectable. In any way, reading or writing them with CHIRP on v2.11A and v2.13A works just as well as with v2.13C.
