[Elecraft] Audio Improvements on a K2

[Clif Squires]

Ron:
I have had a ton of trouble with the KSB, mine died with no way to null
the carrier.
So on to a second KSB.  SSB in xmit still didn't work until I saw your
post about the filters.  I had changed the BFO settings while using
Spectragram including settings on FL1.

Is FL1 used the xmit mode and when I changed factory recommended
settings, all went wrong?

After changing back to recommended settings, my voice sounds *near*
normal and the mic works again.  Can I tweek current setting on FL1 to
optimize sound?

The spectragram mod only allow one to change FL2-4, not FL1 and now I am
seeing why.

TIA &  73,
