[Elecraft] [K3] Odd transmit power output behavior on TX DATA

[David Hachadorian]

It could be a momentary high SWR when starting a transmission because of 
some slow switching somewhere in line. In K3 Config, try increasing the 
value of Tx Dly.  I have to set mine at 14 because of a slow amp.

Instead, it starts about 40-50 watts, and then slowly creeps up to 100 watts. This takes about 4-6 15 second FT8 transmissions.
