[Solved] My GD-77 stop transmitting

[OH0KCE]

Hi All
After change back to Radioditty FW from Open GD77 my HT not transmitting anymore in digi-channel-use.
Transmitt on Simplex are Ok!

I've try different code-plugs and changing FW several times, but no luck.
Some hint anyone?

There have been some problems with the official firmware corrupting the calibration data, but AFIK it normally stops the radio working on both FM and DMR

Did you backup your Flash and EEPROM and Calibration data, using the OpenGD77 support features in the CPS?

Nope, but i do the same thing to my no.2 GD77 and this work ok. Maby i take backups from it.

Don't restore the Flash or the Calibration from your other radio as the Calibration is contained in the Flash and is different for each radio

Please zip your calibration file and post it here

OK

Probably the official firmware has corrupted the calibration data.

This is a very common problem with the official firmware !
