[Elecraft] K3 suffers from amnesia

[Don Wilhelm]

Udo,

Do you have MCU firmware 5.33 or later loaded?
Did you set the PTT-KEY menu to use "UNSAFE" mode (or activate PTT-KEY 
by other means).
See the Firmware Release Notes for MCU version 5.33 dated 8-03-2015 for 
the full explanation.

73,
Don W3FPR
