[Elecraft] K3 BETA FIRMWARE RELEASE -- MCU rev 1.94 / doesn't work at all (?!)

[Frank Lammel]

I loaded rev 1.94 yesterday evening. My main problem is the not working 
VOX in 1.88. However it was more worse than with 1.88! Once set to VOX I 
couldn't set it back to PTT. It switched the whole time to TX, no matter 
what MIC gain settings I choosed. (Oh, I didn't tried the VOX gain, it 
is still at 35, maybe this would help?!). Well, also the TRX seemed to 
had some kind of other problems. All LEDs swichted to on and off again, 
the display get's dark and some relays clicked. Then it came back. This 
happened several times.

Does anybody had similar problems? Or did I make another mistake?

73!
Frank, DD7ZT
