I don't own one, but as I recall, the base tt3 firmware doesn't have the settings for fhe radio part - freq, etc.
TT3 v1.42 appears to be specific to the TT3 Plus.? I didn't see any MT-RTG files in Downloads.
You could try using TeraTerm or the likes to set see what settings are available in that firmware.? Connect and type "display" to get a full listing ("export") works as well.

I have a?MT-RTG FA v1.8 2014-3-10 that was purchased as a WX-Trak version to interface to Peet Bros. Besides testing it has sat on a shelf as a spare and now I am looking to convert it back to a normal APRS beacon.
I see it has the bootloader so I think I should be able to convert it.
I thought that putting the tt3 v1.42 firmware in it would do the trick but it now does not transmit. I am presuming this is because there is some magic sauce in the FW for the RTG to drive the transmitter that the normal tt3 firmware does not have.
Now it flashes green on start. Goes solid green on GPS lock. I never get a red TX indication or see/hear it TX even on startup or after GPS lock.
I do get the bootloader _1 by holding the b key at 19200 on startup.
I presume it can be reloaded but where do I find the firmware to do it?
