Bill, I have seen these comments or arguments before about the RF gain and
s meter, and I never had any problems setting the RF gain or threshold, In
fact I use an old version of the firmware 1.367 where I have to use the
threshold and RF gain seperately. I use this version because the sweep is
very real time and the firmware seems to be stable for me.
However, with the RF gain reduction increasing the s meter in 2.0 and O2,
I have to increase the RF gain to give a s meter reading.
With the 1.xxx versions the s meter is always active and real time and easy
to give a report. A lot of this has to do with the way a person operates
his rig and his own preferences. I would prefer to have the s meter active
regardless of RF gain setting.
AS far as the antique receivers are concerned, their day has passed and
maybe it is time for a change concerning this issue.
