Hi.
?
New version of the modified BASE firmware with FM squelch -
This time I decided to push 2 versions - with r2 suffix and with r2_plus15.5
Second is for the radio with issues with output power due to hardware difference, 15.5 means +15.5 dB to the TX signal level.
?
Full changelog:
- Added FM squelch
- Removes DC offset of demodulated AM/FM
- Reduces some clicking on mode change. Only FM->AM still remains, not found a way to solve it.
- Default compression ratio changed to 2:1
- Added a control for compression ratio and compressor on/off (will be in the next R1CBU GUI)
?
Also, I found a way to add more controls for the MAIN -> BASE communication, by using gaps (unused bits) within i2c registers. It might be handy to make a compressor (or other features) more flexible (tuning compressor/gate threshold, makeup gain, etc). Such features might be added to R1CBU, but maybe someone will add the same to OEM gui application.
