K3 beta-test firmware revision 2.72 (with DSP rev 1.98) is now
available. Anyone who has the KDVR3 (Digital Voice Recorder) installed
will need this revision to use the DVR. We'll be making further
improvements to DVR functions in later releases. Full details appear
below.

MCU 2.72 / DSP 1.98, 12-9-2008
Misc. Changes:
* LINE OUT INCLUDES TX AUDIO: LINE OUT (nor menu setting) now includes
transmit sidetone and speech/data monitor audio.
* IMPROVED TX PASSBAND FLATNESS FOR PSK31: When operating in PSK31
mode via a PC, high-pitched audio tones are no longer attenuated more
than
low tones.
Support for Digital Voice Recorder option (KDVR3):
Note: The following information is more accurate than the DVR
instructions in the
K3 rev D owner’s manual.
* DVR ICON: The DVR icon (dual arrows--above the S-meter) turns on
whenever
the DVR is in use. The icon flashes slowly during all record
operations, and quickly
during play.
* DVR TX MESSAGES: Message record, play and repeat are functional.
(Message
chaining will be added in a subsequent release.) To start voice message
record,
tap REC, then tap M1-M4. Record will start immediately. Tap M1-M4 again
to stop recording. To play a voice message, tap M1-M4. To repeat a
voice message
(e.g., a CQ), *hold* M1-M4 rather than tap. Message play or repeat can
be
cancelled at any time by tapping REC.
* DVR RX LOOP: Hold AF REC to start receive-audio recording. Hold AF
REC
again to stop record. Up to 90 seconds of audio can be recorded; beyond
this,
earlier audio will be overwritten. Hold AF PLAY to start playback;
press any
switch to stop. VFO B will show the playback position in seconds,
relative
to the most-recently recorded audio segment. During PLAY, you can move
forward/backward through RX audio loop buffer by rotating VFO B. An
asterisk
(*) beside the seconds counter shows the extent of the most recently
recorded
segment. Note: It is OK to record received audio continuously; this
might be
useful as a way of catching audio events that you wish to examine later.
Record will continue even if you transmit. However, at present, silence
is recorded
for the duration of any transmission.
* DVR RX LOOP PLAY IN TX MODE. First, enter voice transmit mode by
holding
PTT or tapping XMIT. Then hold AF PLAY to start playback, and press any
switch
to stop. CMP (speech compression) is automatically disabled. Note:
Playback
volume of the RX loop buffer during TX mode is not yet adjustable.
For software developers:
* VOX STATUS ADDED TO IC CMD (separate flags for CW keying ‘VOX’
and voice/data audio VOX).
