[TenTec] Question re Orion vs Icom IC-7800

[W0YG, Charlie Summers]

Icom used glowing terms to describe their 7800 radio, terms that really 
don't relate to meaningful test results.  This is called specmanship.  Icom 
based its specs on 100kHz and 20kHz spacing as I recall, essentially 
meaningless for us Orion types.  Close in, as in 2kHz spacing per Sherwood 
Engineerings website listed below, are impartial test results which show how 
well the various receivers compare.  This is where the Orion shines with the 
600 Hz INRAD filter.  The 7800 falls off a bit at that spacing because the 
interfering signal is inside Icom's narrow roofing filter.

73,
