[TenTec] OMNI VII Comparison Test

[Ron Castro]

Having the S-meter software compensate for preamp and attenuator settings is 
something I have been asking for in the Orions for quite a while.  My trusty 
TS-870 compensates for the preamp (menu selectable) but not for the 
attenuator settings.  The real thing I was interested in though was the 
accuracy of the S-meter readings in the 'normal' situation of no preamp or 
attenuator.  The Orion II reads about 2 S-units low on signals below S9 and 
10 to 20 dB high on signals over S9 based on my testing with a signal 
generator as shown in the chart at this address:

It seems like this would be an easy thing to fix in the software, or for a 
more low-tech solution, have a new meter face silk screened.
