Same, but on sort of an isolated island, hi. Anyway,
just now, mid-afternoon, my noise levels on the
20 meter band (using a little C3, 2 el. beam) and
on the 40 meter band (using a tuner matched 132
foot center fed doublet) are the same: about
S1 to 1.5, or something like -118 dBm or so
(estimated using the very accurately calibrated
Ten Tec RX-340's S meter which is calibrated
in dBm) or around 0.3uV or so. And, on the same
doublet, matched on 80 meters, the noise level
is about S2, or 0.4uV, -115dBm, these at
2:45 in the afternoon, HST (00:45 UTC). These
are the usual noise levels here. How do those
compare to yours, Carl?
I also find Carl's AGC settings to be very satisfactory;
and I have tried Sinisa's settings in his "Using Orion's
Receiver" posting. Problem was, I never had enough
noise to achieve the 2 S unit or so noise deltas with
the antenna connected or terminating the Orion in my
Bird dummy load! Just too quiet out here, or........ am
I still doing something incorrectly?
Anyway, my 2cents on that topic.
BTW, don't ever push either the User 1 or User 2
buttons UNLESS you have read the manual and
know what they do/how to set them up. Should
you have the rig just the you want it (all adjustments
to your pleasure) and you inadvertently push one
of those buttons ---------- blam, you are back
to some sort of default, factory settings, I guess,
and no way have I found to recover where things
were before!! Doing that wiped out everything I
had set up for the stacking registers in every band,
and all the stuff that stays the same when changing
bands, etc. Just all was gone!
