[Elecraft] [K2] Low sensitivity with variable-bandwidth filter

[Bill Coleman]

Fortunately, I found the Rework Eliminators easily.

Swapping out the KSB2 for the eliminators didn’t evidence a change in the CW variable bandwidth filter.

It’s weird, it appears to be working OK at the moment, but the CW 1.0 filter sounds weird. LSB and USB sound a little weird, too.

I wonder if the BFO calibration may be off. Perhaps I should do a CAL FIL and see where it leads me. Indeed, I probably should re-align the whole rig, it’s been several years since I’ve last done it. Ah, yes, September 2015 was the last time.

I’ve also had an issue with INFO 080 occasionally. When the rig is first turned on, I’ll get this. Earlier when this happened, I tore into the rig and removed every module. Still got INFO 080 on power-up. After the rig is on a while, however, it generally starts behaving.
