@ -3,16 +3,18 @@ Morse Code Beacon
Test beacon will transmit and wait 30 seconds.
Beacon will check to see if the channel is clear before it will transmit.
TO-DO: Radio chip audio AGC too slow in responding to tones, worked around by playing a 6khz tone between actual dits/dahs.
Should work on adjusting AGC to not require this.
