General operation:

After power is applied, the device will  send the idstring via morse code as FM modulated tones.  Next, a programmable number of beeps ( or tones) are transmitted before repeating the sequence.

Prior to each beep, the data interface is checked for inbound commands.

Command mode will be entered when you press the '!' key.

Command Mode:

The following commands are available to control the radio beacon:

Notes:

  *  Beep timings are approximate due to the delay when changing radio modes

The 'mspeed' parameter controls the timing of the morse code characters (in milliseconds)
