[Elecraft] Is this another K3 glitch???

[JIM DAVIS]

Gentlemen,

A few days ago I was listening on my K3 on 20m (either mode/band segment) and instead of the usual 
"S5" noise indication on my S-meter it was only (S-1) even with the preamp on! This also occurs on 
17m as well! While all the other bands show the regular/typical reading (S-5 plus or minus a 
smidge!) I know the my C3 yagi works on those bands because we also use a Icom 7200 (standby rig) 
and it's S-meter readings on ALL BANDS including 20 and 17 are NORMAL/as to be expected!

Any IDEAS???

Regards,
