[Elecraft] QRe: K3 K3DSPUPG note

Be sure LO CUT is set to 0.00 and not 0.10.

I just re-verified RxEQ1 and RxEQ2 work great on the new DSP board under 
these conditions, which are the same as before.  The K3 "default" 
behavior is to cut off low frequency audio unless you deliberately shift 
LO CUT (see firmware release notes for MCU 3.41/DSP 2.37 10-02-2009).

PS - I am using the latest pre-beta firmware, which I can send you 
directly if you wish.  It has no intentional changes in low frequency 
response beyond the current public beta firmware.
