[Elecraft] PB=.01

I was quietly excited to see that the bottom two band were actually
able to do something when in that mode.  Makes me think that maybe its
not the audio section but something in the firmware that is rolling
off the bottom end...

That's my bet.  Schematically, there's no reason why the first Rx EQ band 
should have been ineffective until now when using a minimum of 100uF caps at 
the H/P output.
