Tonno: I sounds like there may be a problem in your radio. I am using my
Orion II with 2.037j in the 160 meter contest this weekend with NR and NB
with BW down to 100 Hz with no problem. Maybe reloading the firmware or a
master reset will cure the problem, but if not, you may have to send it to
the factory.
I am familiar with the S-meter problem. In most cases, you need to subtract
about 20 dB for signals showing more than +30, and add 2 S-units to signals
less than S-7. You can see the chart I made using an HP 8640B signal
generator at my website www.n6ie.com. This discrepancy is probably a result
of the new dual-loop AGC scheme in version 2, and can be fixed in the
firmware, or if Ten Tec wants to take a 'low tech' approach, by making a new
replacement face for the S-meter with the right calibrations. The could fix
the power output calibration on the meter that way too!
