Looks like an hardware issue (defective Power Amplifier in the 4-in-1 module ?), I'm sorry but I can't help more. Contact banggood, but they won't reply until the 15th because of Chinese new year, and they'll probably ask for a video of the problem, which might not be easy ...

I think banggood / gearbest / aliexpress has stopped selling this kind of module as spare parts. Now they only have modules for Devo transmitters.
Anyway, it almost costs the price of a IR8M ... If you ever get a refund for yours I'd recommend getting a T8SG V2 (not lite) instead.

There's one for sale for 65€ on "Le Coin Coin du FPV" on facebook:
www.facebook.com/groups/571655186331296/..._id=1214387965391345 (you need to be a member of the group)
You may get it if you're quick enough :)

edit: that's a T8SG V2, not a T8SG V2 Plus, the gimbals are not as good but that's still a good transmitter.

There's something you can try, in AFHDS-2A protocol options (click the protocol name in Model Settings menu), try to change "FREQ TUNE" value, in 20 KHz steps then check if that's better.

You're only interested in modifying FREQ TUNE, the other settings won't have any effect on your problem.

goebish, I suspect that factory firmware use modified HAS_4IN1_FLASH support, and Deviation version doesn't switch 4in1 module PA lines (PE1 (3) and PE2 (4)). It can be tested with different protocols, probably IR8M has normal output power for one RF chip only (CC2500, NRF24L01, A7105, CYRF6936).

With original firmware I get >2km with FrSky receivers

@vlad_vy that's a possibility ... too bad iRangeX didn't offer to send a few transmitters to developers ...

@david drones, please share your modelXX.ini, I'll try to reproduce your issue.

Connect your transmitter to your computer in USB/FileSystem mode (hold Enter button then switch on transmitter) then post the model file that crashes when you move AUX4.
