Funny what one finds when digging through old files looking for something
else.
In 2004 I tested my brand new Jupiter during the CQ WW DX CW contest and did
a write up of my opinion.
My results are nothing like the lab tests that Rob Sherwood makes, but they
are a lot like his comments that he makes after using the radios on the air.
You guys know me. I don't hold my punches. I call it as I see it, and I
also sent the results to Ten-Tec (including audio files).
That resulted in provision for a pre-selector being added to the Omni VII
design.
I really enjoyed the Jupiter. It is one of the most enjoyable radios I have
ever operated, but it is not a great contest radio for the harsh European
conditions.
Here in Europe, if a radio's IP3/BDR3 performance is weak, you get nothing
but garbage in the receiver on 40m at night, until you add a lot of
attenuation - or use a preselector.
If the radio's IP2 performance is poor, at night you get 41m band broadcast
stations flooding the 20m band with carriers every 10 kHz.
Again a preselector works wonders for this problem.
I later tested the Omni VII (prior to its production). I will upload the
short test later (gotta find it). Perhaps I'll even upload the long test
with several audio files. My pre-production unit had the pre-selector
option built-in when I got it. I was able to test it with and without
pre-selector.
Here's the Jupiter:
