Bob's a great op, so I really appreciate seeing his settings. But 
they're all run together in his email with no paragraphs or punctuation, 
so it's very hard to read. I copied his settings into a word processor 
and added paragraphs.

First, set *CONFIG:TECH MD ON* to un-hide some AGC settings.Set 
CONFIG:TECH MD OFF when finished, to eliminate distracting values from 
accidentally appearing in the SubRx display (PLL1, AFV, dBV, etc.)

*AF GAIN LO* -- Cuts audio hiss.May not work with all headphones.OK on Heil.

*AF LIM 20* -- Only takes effect when AGC is OFF (rarely used)

*AGC DCY Soft* -- Reduces AGC-induced IMD, recommended for pileups

*AGC HLD 0.05* -- Slow AGC hold time (50 ms).Reduces AGC-induced IMD, 
recommended for pileups.Works with AGC-S only, no affect when using AGC-F.

*AGC PLS NOR* -- Loud static pulses do not pump AGC

*AGC SLP 010*-- A pretty "flat" AGC response curve.I may move this lower 
since pileups of loud guys can blend together, but I like this setting 
because it saves my ears.

*AGC THR 010* -- AGC kicks in at about S-8.Signals lower than THR behave 
as they would with AGC OFF ( +1 dB of RF = +1 dB of audio)

*AGC -F 120* -- Factory default fast AGC decay rate (recovery 
time).Higher = faster.Faster can be bad.

*AGC –S 20*-- Factory default slow AGC decay rate (recovery time).Higher 
= faster.Faster can be bad.

*RF GAIN at 3 O'Clock or less* except when all signals and band noise 
are very low (e.g. 10m)

*AF GAIN* never higher than 3 O'Clock

*AFX OFF*

*NR OFF*

*NB OFF*

*RIT OFF*

*XIT OFF*


FL1 to FL5 BW set to match labeled filter bandwidth exactly, not wider 
or narrower.

Use *AGC-F* or *AGC-S* for CW, whatever works best for you.

Use *AGC-S* for SSB.

CW Pitch 500 (or to taste), IF shift centered (on CW)

500 Hz InRad 8-pole filter on CW

2.8 kHz 8-pole filter on SSB (1.8 8-pole when bands crowded, *must move 
IF SHIFT lower for pleasing audio*)

Use *XFIL* button to toggle between filters and reset the IF shift, 
rather than NOR (hold) button

*PREamp ON* for 15m and up, *PREamp OFF* for all other bands
