[TenTec] Orion Sweep - Mark

[N0KHQ at aol.com]

Hi Mark,

The Orion Sweep is similar to the Jupiter in respect to the width of the of 
the signals shown. This is adjustable by varying the bandwidth.

Right now I have the Orion Sweep size set at 72khz, the Bandwidth set at 3K 
and Roofing Filter set at 6K. By decreasing the Bandwidth from 3K to 1.8K the 
Sweep samples become narrow.......and that's what is supposed to happen. When 
the Sweep size is set to 32khz and the Bandwidth is left at 3K the samplings 
will be "fat". As you reduce the size of the Bandwidth down to, lets say 1.8K, 
the samplings begin to narrow. This is expected.

As a former IC-756Proll owner. I must say that the Orion Sweep is as good or 
better. The 756Proll should not be used as a standard. (TT sets the standard 
for excellence) It is best to sample the audio signal from the Orion "Line Out" 
to a PC based Spectral Analyzer, I use Hamalyzer for all of my work and 
testing.  

I would imagine that the "real" Sweep testing will come those that run CW. 
This should get pretty interesting.

The Orion Sweep has been running all day with no signs of erratic 
behavior........just smooth and accurate.
