[CQ-Contest] Re: ON4UN and the Ten-Tec Orion

Though I have strong doubts as Mario, this one is not warranted.
I will await with anticipation the ARRL Lab tests.

With modern RTTY programs and TU's, you can copy RTTY with one
of the tones completely missing.  This is because all of the
good ones for two decades after Dave Mills taught us all how,
use a sliding threshold for the slicing detector.  Given the
constant group delay through the FIR filters in the radio,
I suspect John's statement about RTTY to be completely
correct.  Do not try it however under weak signal or QRM
conditions.  That test is a strong signal test primarily.

ON4UN> Copy of RTTY is flawless with bandwidth down to 150 Hz!

Orion even beats the laws of physics as hamradio RTTY works with 170 Hz
shift at 45 bauds!

Just doing Windows XP update and Symantec antivirus download enjoying my
soft PC...
