[Elecraft] HI SIG

[Erwin Witt - DK5EW]

Hi all,

last evening I switched on my K3 and got direct "HI SIG" in the display. I
dsconnected all cables but still the same. K3 is not RXing anything anymore.

Strange thing is that the morning I was operating my K3 (serial # 5776) as
normal and switched off after. 4 days before I updated firmware to latest
one but had no problem last days when operating.

Any help on that ?
