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.
