hi Ken,
Thank you very much for the info. It does make for a more expensive radio to
build. I had a TS-870 and realized the difference between the dsp in the if as
opposed to the dsp in the audio stage. Not much but subtle. i had the ic proII
also. I buy my radios used and re-sell sometimes making a few $$ somtimes
loosing a few $$ and just consider it rental on a rig i had fun using for a
while. After owning many many rigs throughout the years I have come to realize
that a $200 radio like a TS520 still gets the job done like a $3,000 radio.
When it comes to a crowded band with strong close in signals and qrn the big $$
radio is a pleasure and the low $$ is very very rough if not impossible to copy
the weak ones. It's a challenge and teaches one to use all the knobs to the
best of their ability. I now like the middle class rigs and have been exploring
tentec rigs for about a year now. My paragon fits the bill perfect for my hf
needs and i like the broadcast band recieve. I also own a
526 that is fun when 6 is open and on a weekly 6 meter net. I have a delta
580 i use in my truck mobile. I thing i have finally found satisfaction with
these rigs and will not part with them like i have in the past with various jap
rigs. Can't justify a move to an omni VI, i'm too happy where i'm at now but i
was curious as to what the difference was.

Hi Larry,
The Paragon is a general coverage rig, and the Omni VI is not. Being
general coverage requires wider bandpass filters in the receiver front
end, given the same number of bands to cover 160 meters to 10 meters. In
fact the Paragons use eight low pass filters to cover 100 kHz to 30 MHz,
using a single filter for 10 and 12 meters, another 17 and 15 meters,
and one for 40 and 30 meters. The Omni VI has nine dedicated bandpass
filters, one for each amateur band from 160 to 10 meters. In most
situations this will not make a noticeable difference. However in the
presence of strong out of band signals or interference sources the Omni
VI first mixer has less total power input to deal with. So in a multiple
transmitter contest station environment, or near SWBC transmitters the
Omni VI would likely have a lower minimum discernible signal.
The 9 MHz IF (first IF in the Omni VI and second IF in the Paragon) has
6.0 kHz and 2.4 kHz BW filters in the Paragon, whereas the Omni VI has a
2.4 kHz and one or two optional narrow filters (depending on version of
Omni VI) , one of which can be cascaded with the default 2.4 filter. The
Omni VI does not have AM mode, so does not need the 6.0 filter. This is
another reason that the following IF stages have less total power to
deal with, and are less likely to be driven in to nonlinearity, making
reception of weak signals amongst strong signals in a crowded band better.
The first local oscillator in the Omni is also much different, covering
smaller band segments and using a much less complicated phase locked
loop system. The result is that the first LO in the Omni VI is probably
quieter. Also the Omni VI does not even have the second LO that the
Paragon has, another possible source of noise.
Version 2, 3 and Plus Omni VIs also have DSP noise reduction (in the
audio, not in the last IF like an Orion, TS-870 and other newer JA rigs)
which the Paragons do not have.
For the mostly rag chewing ham, these differences will not often be
noticed, and lack of general coverage in the Omnis may be a reason to
own a Paragon instead. For a contest operator or a low band DX operator,
the differences may very well be noticed. They are all excellent rigs.
