Test beacon will transmit and wait 30 seconds. Test beacon will transmit and wait 30 seconds.
Beacon will check to see if the channel is clear before it will transmit. 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.
