[chirp_devel] Baofeng - Programming specific RDA1846 codes via Chirp possible?

[David Ranch]

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?
