With a special easy cable pre-soldered to the audio board that makes it very easy to add to your IDOM4 (or IDOM3). Simply use the IDOM4 manual to see what wires go where on the IDOM4, plug them in and solder. NO stripping 10 ends of wire! (wire colors may vary)

ID your repeater, build your own voice keyer or just annoy your family and friends. This is the voice recorder board used with the ID-O-Matic IV repeater controller. This board will record and play back a 10-second voice messsage. Simple to use; hold down the REC button to record the message, and press the PLAY button to play the message back. The on-board audio amplifier is enough to drive a small 8 Ohm speaker, and there is a microphone on board as well.

These boards have no header pins or speaker connectors, since they are not needed with the ID-O-Matic. Solder pads are provided for off-board connections.
