release v.19.9
馃棽FLASH WITH A BROWSER馃棽
Fixes:
- fix AM audio clipping in spectrum bug introduced in
v.19.4
- the sticky squelch solution was resetting the AGC during RX, so the audio was overloaded each time the AGC was reset
- #76 - remove beep on startup option
- add slight delay to spectrum RSSI read during active RX to save battery life
- charging indicator turned off, as it doesn't work anyway
