DRU-3 DIGITAL RECORDING SYSTEM
(OPTIONAL)
The DRU-3 DRS unit allows you to record
approximately 15 seconds of audio per channel on up to
4 channels. The audio is input via your transceiver
microphone. Once recorded, the audio can then be
transmitted. It is also possible to make longer
messages by consecutively sending the contents of
message memories. Finally, you can even send this
longer linked message repeatedly by using the Repeat
function accessible via Menu No. 39 (REPEAT).
The DRU-3 is useful in many situations:
DX chasing or contest operation where repeated
calls are necessary for extended periods of time
Checking interference complaints to other equipment
(lets you be in two places at one time)
Checking or adjusting your transmit signal or your
antennas if it's not convenient to be sitting in front of
your microphone
Helping a friend adjust his antenna or receiver when
he needs repeated test transmissions from you
Once you begin using the unit, you'll likely discover
other applications.
