[Elecraft] K3 Momentary no transmit

[Jim - N4ST]

This drove me nuts when I first got my K3S.
After a few days of testing and reconfigurations, it turned out to be a
firmware problem that has existed for years.
You will never notice it in SSB modes and the dropout occurs in the spaces
for CW.
A definite annoyance for those of us using digital modes with transmit times
longer than 15 seconds.

I discovered a problem with my K3, s/n 83xx.
With nothing but power and a dummy load connected to the K3, while in TUNE
on 10 meters, PWR adjusted to 15 watts, the K3 momentarily stops
transmitting every 15 seconds.
When I push the TUNE button it starts transmitting.  After 15 seconds the K3
momentarily stops transmitting for about a millisecond, again at 30 seconds,
again at 45 seconds, and again at 60 seconds and so on.
The same result in both CW and DATA modes.
If I reduce the power to under 12 watts, the K3 transmits continually.
Has anyone experienced or duplicated this characteristic with their K3?

Thanks/73,
