[TenTec] DSP Engine in New Rig?

[wo8l@att.net]

Hey Larry,

I read your posting on Ten Tec's DSP with interest.  
What you're describing, though, is not so much problems 
with the Pegasus and Jupiter.

Actually, you pretty well describe the nature of DSP as 
it's currently available in most mid-range ham rigs from 
virtually all manufacturers.

I have used the Pegasus and can assure you that its 
audio is no more or less "mushy" than the sound of my 
Kenwood TS570S.  In addition, the Kenwood has weaknesses 
which the Pegasus doesn't and vice-versa.

DSP filtering, whether at the IF level or the audio 
level, is easy to use and very versatile but does come 
with some compromises in audio quality, receiver 
selectivity and receiver sensitivity.

To avoid these compromises, the consumer would need to 
jump to a higher priced and more complex rig.  The 
Pegasus/Jupiter and its host of competitors are just 
what they're designed to be.  They're medium priced, mid-
range performance rigs which do the job for most hams 
for both domestic and DX contacts.

The difference in receiver performance between my OMNI V 
full of filters and the Kenwood TS570 or Jupiter are 
obvious to the experienced ham who wants the best.

However, a new OMNI VI+ or Kenwood TS-2000 with optional 
filters carries a price triple a Pegasus.  Combined with 
a decent beam or even a vertical, the typical ham can 
work all the contacts he or she can handle with the less 
expensive rig.

It all depends upon one's preferences, I guess.

Lots of hams like to cuss and discuss all of the varied 
strengths and weaknesses of various rigs.  

It reminds me of the endless arguments about which is 
bettter, a Chevy or a Ford. Myself, it doesn't matter.  
They've all got good features and weak features.

Similarly, the perfect rig has never been made.  But the 
Pegasus/Jupiter and its competitors sure pile up the DX 
at a reasonable price compared to the boat anchors we 
hams once used.
