Hello Dave,

Ok, thanks for the confirmation on what Chirp does today. I am curious though if what Chirp downloads as an img from the radio is the complete radio image? If it is a complete image yet it only modifies the channel/freq/features areas, there still might be some hope that someday, a "very advanced" area could be added to flip these specific bits.

While I'm at it, I'm curious what people think about this specific 9600 baud hack that this HAM did. In an analog radio, one would need to tap into the discriminator to get a wide enough & flat pass
band to support FSK over FM. Since these Baofeng radios are SDRs and pack everything into a few ASICs, I don't know if getting into this stage of the radio block is required anymore.

Thoughts?

Most likely requires direct programming via i2c.

Chirp only modifies the memory map, not the firmware. I took a look at the Chirp source driver for the uv5r.py, and it appears to only contain channel/freq/features settings, nothing low level like the RDA1846 codes. This is consistent with most other radios as well.

hope that helps,

Dave
