Sepura / Simoco SRM1000 TETRA radio firmware upgrade file (CLEAR, so likely no crypto stuff)

I also have some firmware .BIN's for Ericsson P25 and P42 (model, not mode) handheld radios. Directly dumped from their 27C256 firmware EPROM's. But we have figured out the channel programming for the radios already. But maybe some HD6303 code might be interesting?

I have some 410 - 430 MHz and one 380 - 400 MHz band models of these for playing around.
But they absolutely don't like going out of band.
For example to the 432 - 438 MHz amateur radio band here.
If you mod the CPS to accept channels above 430 and program in, say 433.350 MHz to the the radio, it just boot loops.
Thankfully recoverable by programming in some in-band channels.

@ftg @whitequark I’ve got a few 380-400 units here. Most won’t boot. Never got around to investigating out of band use but that does not sound promising :/ did get one running and attached to the test set. Unsure if they can do direct mode even.

All of mine can do DMO.
I have the 410 - 430 one's on a 417/427 commercial pair for hobby use.
My plan for the 380 - 400 is to stuff up and down converters in it and see if it works for 70cm DMO.
