Voice Keyer Problems

[Matthew Cook]

Howdy All,

We're currently having a few problems the Digital Voice Recorder in one of
the K3's we're using in the IARU contest (in progress).  The radio is
a very late model K3 that was purchased & picked up at Dayton on the
weekend the K3s was released.  As usual a gremlin has crept into our radios
at 2AM (local) in the middle of a contest sigh....

The Digital voice recorder is doing a few odd things when placed in the
automatic "repeat" calling mode;

   1. randomly locking up and not returning control after playback complete
   2. stopping prematurely before the end of the playback
   3. randomly replaying white noise for the entire playback period

For situation 1 we can reboot the radio (power off and on) which restores
operation for a while.  The last two issues will resolve them selves on the
next activation of the voice keyer (manually).

We're wondering if we have to pull the KDVR3 out of the radio for repair,
or is there software options/versions available that we can upgrade ?  Has
anyone experienced problems like were describing?

Sounds to me as though a bit of RFI is causing issues.   I trust there
is adequate isolation physically between the station and the antenna and
that you are employing a Common Mode Choke on the feedline at the
transceiver.
