[Elecraft] K3 # 282-LSB RX AUDIO LOST

[Nand Kishore]

Yesterday,while chasing ZL8X on various bands and modes,on 40m LSB
I could not get RX audio.Changing to USB got the audio back.

Checked on other bands,toggling between usb/lsb gives dead silence
on lsb.
RF gain wide open.Af gain same all bands and modes.AGC-F. Filter
as wide as can go.No VOX ,only PTT in use.
Latest regular F/W installed.

Any clue?
