Sad day at AA6E

My FlexRadio Systems model 6500 transceiver has gotten a serious bug, dropping frequency lock periodically.  It may arise from operating with the GPS Disciplined Oscillator -- and summertime high ambient operating temperatures.  Back to factory it will go.

The following crude video shows how this looks when listening to WWV (15 MHz).  Problem tends to develop after high duty-cycle transmission (JT65 - 50 W) for a few minutes.  It sometimes goes away if the radio is left in receive for a long while (10+ minutes).
