Thanks for this info on Doug's write up about DAGC. If anyone needs to
print it, I have a Word version I'll be glad to send.

Hi,

In recent days(2/9/03),  Doug Smith has posted detailed design
info about the AGC and ALC systems in the Orion.  Very
interesting reading;  have a look:

http://www.doug-smith.net/digitalagc.htm

I trust the Orion User's Manual will have several
sample examples of set ups for the Programmable
AGC features.  I really have no idea how to establish the
AGC characteristics to be optimum for various modes/band condx:
(1) AGC attack,  (2) the peak-hold or "hang" function that 
retains the most recent peak for an adjustable period of time,
(3) the decay time!  Quite a change from just the Fast or Slow 
AGC selections we have had,  hi

Anyway,  more neat info to digest as we await the shipping
of our Orions!

73,  Jim  KH7M
