[Elecraft] K3 - RX Problem after latest firmware update

[Stewart Baker]

Greg,
Have re-installed V1.75 & V1.57 again, no change.

Here is a sequence which you might like to try:-

POWER
80m LSB 3780
NORM
LO CUT=0.15
SAV ALT1
NORM
TX ON/OFF
ALT1
TX ON/OFF
Receive may be dead at this point

If not continue with
Select USB
ALT1
TX ON/OFF
Receive dead

Switching bands, modes or NORM always restores receiver.

I do (from my point of view) hope that I am not the only one with 
this funny..
