[Orion] Question about noise floor

[BarryG]

Thanks to Bill and others for informative comments.  It seems that although Ten-Tec has made an unprecedented effort at providing technical information on the new rig, the AGC action really hasn't yet been comprehensively described - especially in terms of its action on weak signals, algorithms used to determine amplification/compression, etc.  This isn't to say that Orion owners can't learn how to make best use of the AGC through practice.

"It's almost as though the AGC detector measures the total POWER in the bandwidth rather than a voltage LEVEL, and then adjusts for constant noise power output."


Perhaps whatever processing algorithm is behind this would explain why some folks have characterized the Orion as sounding noisy with no antenna connected . . .
