[Elecraft] Help with missing Filter-Control "Shift"

[KD7YZ Bob]

Howdy K3' people:

There's a 6m opening to South America right now. The most I am working
aere CW in the Brazil and Venezuzla region.

CW.

I've been making great use of the filters, my 8-pole matching, and so
forth.

Suddenly I have no control of the upper-left knob. No Shift. No "Lo". If
I push it in, the beep goes butI see FC*060

usually I could shift the filter response drawing back and forth.

If I hold it in, I get <NOR> but still no control

Somehow I also can get a QRQ off or QRG off .. dunno, can't make it
happen every time . may not be related.

Mainly, pushing upper-left knob makes the green LED go from Shift to"LO"
and the width LED to "HI"
