[Elecraft] K3 DVR issue

[Dauer, Edward]

Today during the NAQP I experienced occasional strange behavior with a new KDVR in an updated K3 . . . wondering if this has happened to anyone else.  The recorder works just right 98% of the time.  Randomly, it hangs up in the middle of a recorded message.  It just stops.  No audio, no RF, but the K3 remains in transmit mode.  Sometimes tapping the same M button again restarts the message from the beginning and all is well. Sometimes, nothing has any effect - nothing will get the rig out of transmit other than a power down.  And then all is well again for a while.  This happens on more than one of the memory buttons, and it happens whether I tap the M button or the corresponding programmed button on the K-Pod.  It is infrequent, intermittent, and of course happens at the worst times.  On one and only one power-down I saw ERR-DVR.   Re-recording messages doesn't fix it.  The K3 has F/W revision 5.64, which may be one revision behind.  Anyone else experienced this or have an idea what the problem is?  Tnx for any advice . . .
