[Elecraft] K3 Momentary no transmit

[Jim - N4ST]

Ken,

This is firmware problem acknowledged by Elecraft, and previously discussed
in this forum
If you don't do digital comms, one of the easiest ways to see this is to put
the rig in TEST mode and turn on the 2-tone test.  Monitor the "transmit"
signal with headphones and you will hear it drop out every 15 seconds.  The
dropout is just for a few milliseconds and sounds similar to a WWV "tick".

There may be some variability in rigs, though I doubt it.  When I was
trouble shooting the problem with Elecraft support, they were unable to
duplicate the problem with the rig they initially had on the bench.

G'morning, Frank:
I just tried to duplicate what you are experiencing and was unsuccessful. No
interruptions. K3 #202 with latest firmware.
