Try without formating :-)
The Orion's S-meter calibration certainly isn't anything to "write home
about," but it is "representative" of the distant stations signal strength.
Running V1.373b5 I get the following readings using calibrated signal
generator and attenuator on 14.058 MHz:
Sig Level Preamp On Preamp Off "Standard
Reading"
50 microvolts S9+11 S8.1
S9
-6dB S9 S7
S8
-12dB S8.1 S5.5
S7
-18dB S7 S4.5
S6
-24dB S5.8 S3
S5
-30dB S4.5 S2
S4
-36dB S3.1 S2
S3
-42dB S2.1 S1.8
S2
-48dB S1.8 S1.8
S1
S1.8 is about as low as the S-meter goes on this release of the firmware
with the RF gain at 100 and the AGC threshold set for .36 microvolts and the
decay set for 200dB/s. I use the "calibrated measurements" when I am trying
to understand antenna performance - particularly "front to back/side"
measurements.
