[TenTec] Omni VII Question

One reason we might be hearing more noise is that the Omni VII has a much 
lower noise floor than the Omni C........if memory serves me,  -128 on 160 
meters VS -140...quite an improvement in sensitivity.  TEN TEC correctly 
reasoned that on the lower bands, more was not needed on the older rigs.

On the lower(160,80,40) bands, I wind up with 18dB of attenuation in and rf 
gain cut back 5% or so most of the time.

(I still wish the "S" meter worked like the Omni VI, though......reduce rf 
gain until "S" meter drops to zero and you are all set......I am unconcerned 
with a lab standard "S" meter since each antenna and installation makes it 
moot.....I know, I know, I am the ONLY guy who liked it that way, but it was 
much nicer to operate "at the noise threshold")

The noise reduction does add some artifacts on cw. I can't use it there.
On SSB is is great in my opinion.  A "Peaking" function like on Omni VI 
would be the cat's pajamas!

The CW filters have 2 issues which I hope are addressed:
1-they need to go narrower, 200 Hz just isnt narrow enough WITH THE SLOPE OF 
THESE FILTERS.

2 the slope of the filters needs to be steeper in my opinion. I feel the 
same way about the cw filters in the omni VI. Not steep enough. (Perhaps a 
choice in slope?)

I find that I am using a lower pitch cw note on the VII than I have ever 
used. It "hears" better with a 500 or 550 Hz note in my opinion.  I have 
used an 800 or 750 note for years. Not sure why this one would be different.

There are still a few things which will be changed, I am sure.

It would be nice if the ATTN followed the bands, but ATTN on other rigs is a 
hardware switch and doesn't follow the bands so it is a nit pick.


Some settings are changed too quickly with the multi knob, some are too 
slow. (perhaps a choice in rate of change?)

The Omni VII is "Different" from the Asian rigs in many ways. Obviously the 
receiver is more bullet proof.
Some "bells and whistles" are missing.  Do we need them? Everyone's answer 
will be different.

In my opinion the Omni VII is the best "launch" of any of the newer rigs and 
it is getting better all of the time.

I am looking forward to the improvements!
