Of course, the best solution would be for the S meter on the Orion to work
just like the RX340.  The RX340 S meter always reads correctly regardless of
RF gain setting, attenuator setting, preamp setting, or even AGC rate used.
It is the only radio I have ever seen that works this way.

By the way, the Orion V1 S meter won't read signal strength below the noise
level (or any radio for that matter) because the noise moves S meter above
the signal level.   This is why the V2 S meter scheme is really ok.  As long
as you don't lower the RF gain so that noise no longer moves the S meter at
all, all signals above the noise will show on the meter.  Toby, it sounds
like you lowered the RF gain too much if you could not get S meter readings
for signals that were above the noise.

point,  if the signal is NOT above the rf gain setting then NO s meter
reading is available,  whether accurate or not, having the s meter to read
actively all the time gives you an idea  of what the relative strength of
the other stations signal is and you can quickly give him a report.

is helpful to have a working s meter all the time,  not just when the RF
gain is turned up high enough tor the s meter to function.  Maybe the
question should be asked,  What is the S meter for anyway? ......to be able
to offer signal reports,  or to see where the RF gain is set.
