Many thanks to Tony (AE0KW) and Eric (WD8RIF) who note that Elecraft has released new a Beta firmware for the KX3 and KX3 that extends the time before the radio drops to 5W in CW mode:
- The KX2 release extends CW operating time at 10 W by allowing the supply or battery voltage to go as long as 9.0 V before dropping to 5 W.
- The KX3 release has the same CW power improvement, as well as a fix to the TX inhibit function of the ACC2 jack.
