Using the Digital Voice Recorder
Note: You must have MCU firmware version 2.73
or later installed.
The KDVR3 option allows you to record and play
voice messages as well as capture received audio.
Transmit Message Record and Playback
MIC gain must be set to show 5 bars on the
ALC display on voice peaks for the proper
recording level.
You cannot transmit and record at the same time:
Using PTT: You do not need to press the PTT
unless that is required for your mic to produce
audio. In that case, press the PTT after starting
record or you will transmit, not record. Once
recording starts, you will not transmit even if you
are still holding the PTT closed at the end of the
recording time period.
Using VOX: Either disable VOX while recording or
take care not to trip the VOX until after starting
record or you will transmit, not record. Stop
speaking at the end of the recording period to avoid
accidentally transmitting.
To start recording, tap R E C then tap any of M 1 -
M 4 . The remaining buffer time in seconds will be
displayed as you speak. Tap R E C again to stop.
Hold R E C to select bank 1 or 2 (4 messages each).
Tap M 1 – M 4 to play. To cancel, tap R E C .
To auto-repeat a message, hold (rather than tap) M 1
– M 4 . MAIN: MSG RPT sets the message repeat
interval (1 to 255 seconds).
To play back two memories in a continuous chain,
hold the memory button for the first message until
REPEAT appears, then tap the memory button for
the second message. CHAIN will appear briefly.
The second message will start automatically after
the first message ends.
Receive Audio Record and Playback
Hold AF R E C to start record. The icon will
flash slowly. To stop recording, hold AF R E C
again. The most recent 90 seconds of recorded
audio will be available for playback.
Hold AF P L A Y to start play. The icon will
flash quickly. A seconds counter will be displayed
on VFO B, along with an asterisk (*) if you’re
within the most recently recorded audio segment.
Rotating VFO B jumps forwards/backwards
through recorded audio. To stop play, tap any
button.
To transmit recorded audio, press the PTT or tap
X M I T . If you tap the X M I T button, do so before
starting playback since tapping any button stops
playback.
IMPORTANT NOTES:
1. Messages may be at least 10 seconds long.
2. The recorder takes the audio after the MIC
gain control but before it is filtered and
processed. Compression and equalization
may be applied to playback audio.
