Hi all -
I find it quite interesting that Joe has aid the Jupitor is quieter. I have no
way of knowing since I have never even seen a Jupitor. What I am REALLY curious
about is how the phrase "Quieter" is defined. In one sense, if you hear
nothing,
a rig will be really quiet! On the other hand a rig could be quiet yet in doing
so shut out some signals you'd really like to hear. I know I sound like a
techno
idiot, but I am beginning to wonder what "quiet" is. Anybody care to share a
practical definition of a "quiet rig"?
I have an interesting last two months which I feel has opened my eyes a bit.
When I finally cleared up a few internal shack errors (with George's help), my
756 PRO ran circles around my OMNI V. A took me a little bit of time to sort
out
some problems that I created when I rearranged my shack upon getting the 756 -
mainly ground loops and RFI. (One thing I did was hookup an external audio amp
that is totally cool). Once my idiot mistakes were taken care of I could truly
experience the 756 PRO. It is a phenomenal rig.
Now don't get me wrong, I LOVED that OMNI V and I love TenTec as a company. I
still do and always will. But I have to say that I feel I listened to the
"crystals are the only way" theme for too long and it made me narrow minded.
The
756 PRO is one terrific rig - no matter where it's made.
Now here's the interesting part - once I learned how to use it and got used to
the characteristics of a DSP rig, I realized my "quiet" OMNI was not hearing
sigs the 756 was hearing. I know very little about interpreting the spec
comparisons as shown on Elecraft's chart for all the major rigs, but I do know
what I hear in the shack. So how do we define a "quiet" receiver?

> 1. One button band selection.
> 2. Triple band stacking registers.
> 3. Twin passband tuning.
> 4. Antenna tuner.
> 5. Much better display.
> 6. Better control knob feel, the Jupiter's multi knob

> 7. Less prone to have RF problems in rig.
