[1000mp] IF Gain Menu Setting

[wjs073 at bellsouth.net]

The gain setting is adjustable to take unit-to-unit variations into account.
There is no single setting that is proper for every radio. The procedure I
read, which made a lot of sense to me, was as follows. Find a very weak
birdie that's just barely detectable in the noise (or generate such a signal)
on the 12 or 10 Meter band. Now adjust the IF gain setting to maximize 
the signal to noise. Too low a setting causes both the signal and the noise
to drop. Too high a setting causes them both to increase. But there is a 
point, which may be over a range of two or three numbers (i.e., 12 to 14), where the signal stands out a little better against the noise. Close your
eyes and listen very closely while changing the setting up and down.
You should be able to find this "sweet spot."
