“what may be ‘best’ in a laboratory environment may not necessarily hold in the real world.”
100 percent in agreement with that. I do however recognize that bench/lab testing provides us with a solid starting point for reference in performing tests in other conditions, such as through an outdoor antenna setup. And the variables with that from one installation to another is very wide. All of those things listed are just the scratch of the surface.
I run two Inovonics 222 processors since my station is transmitting C-QUAM, but I have not found any significant benefit to the carrier itself and its coverage range, only the quality of the audio produced through those processors. It could be the result that my station is a Carrier Current system and not a through the air system.
The example described in the previous post is indication that comparisons between units and results can be observed, even with less than optimum testing methods and equipment.
