+ Here's a summary of all of the Pad and Idle mode
+ indications. In Idle mode, you'll hear one of these
+ just once after the two short dits indicating idle
+ mode. In Pad mode, after the dit dah dah dit
+ indicating Pad mode, you'll hear these once every five
+ seconds.

+ |dit dit dit
+ |Continuity detected on both igniters.
+
+
+ |Storage Full
+ |warble
+ |On-board data logging storage is full. This will
+ not prevent the flight computer from safely
+ controlling the flight or transmitting telemetry
+ signals, but no record of the flight will be
+ stored in on-board flash.
+
+ |Additional Igniters
+ |four very short beeps
+ |Continuity indication for the four additional pyro
+ |channels on TeleMega and EasyMega. One high tone for
+ |no continuity, one low tone for continuity. These are
+ |produced after the continuity indicators for the two
+ |primary igniter channels.

+ For devices with a radio transmitter, in addition to
+ the digital and APRS telemetry signals, you can also
+ receive audio tones with a standard amateur
+ 70cm FM receiver. While on the pad, you will hear
+ igniter status once every five seconds.

+ During ascent, the tones will be muted to allow the
+ telemetry data to consume the full radio bandwidth.
+
+ During descent and after landing, a ½ second tone will
+ be transmitted every five seconds. This can be used to
+ find the rocket using RDF techniques when the signal
+ is too weak to receive GPS information via telemetry
+ or APRS.
