[TenTec] Old vs New = crunch time

Wed Feb 3 11:22:06 PST 2010

The one item I might add to this discussion, having owned a Pegasus and now owning an Omni VI, Option 3, and having put good time on other radios such as a TS-870SAT, 756Pro 3, and K3:

Identify your particular receiving challenges, if there are any.  

I am continuing to identify and have corrected noisy power line components that often give me an S8 noise level on 40 meters, which is my main band of operation.  The Omni VI noise reduction is marginally effective.  If the band is empty, I am fine; if it is crowded, it will be pumped by strong signals even several KCs away with the result that the noise appears.  If I try to use the 9mhz IF filters, they delay the signal sufficiently as to defeat the NR.  On the other side when that line noise is absent, I can slide next to any strong station and have good copy on a weak signal.

My point after all this?  The more sophisticated noise reduction on an Omni VII, and perhaps of a Pegasus/Jupiter, might prove superior to what the Omni VI offers in my situation, despite the fact that on paper my roofing-filter equipped Omni VI is marginally better in a band crowded with strong signals than the O-VII, and significantly better than the Pegasus or Jupiter with their 16 bit DSP.

In my environment, wonderful noise reduction algorithms and execution are probably more important than maximum selectivity.  If you have a similar problem with noise, the Jupiter would likely prove superior to the Corsair II or Omni VI.  Without that noise I bet you'd be thrilled with the Corsair II.  The one advantage of the Omni VI Option 3 to the Omni VI Plus is that the Six Plus relies on surface mount construction; I at least have a shot at working on the non-surface-mount boards of my Option 3.

With a budget in the $600 to $1800 range, you can do quite well in  a TT rig, 

Please understand that because of the way the protective circuitry in TT rigs is set up, it is best to run with a TT power supply. NOT MANDATORY, but you are afforded better protection of the finals. You will also want some accessories. I have had several Corsair II's. They fall in that range. They are excellent. You may need to rebuild the PTO (not at all difficult if you have patience and follow TT's directions). 

The basic Corsair II is very affordable. When budgeting, however, don't forget that you'll want the optional filters (you may wish to choose only CW as that is what you indicate you operate(allow $100 to $130 for 2). With the amount of contesting and DX that you do, you'll probably also want the external VFO (Getting hard to find. Allow at least $150). Great accessory and well worth the addition. Add to that a power supply (another $90 to $120) and you're still in your price range. A good operator with a Corsair II can easily out-perform a so-so operator on any other rig. Malcolm's right about the sidetone, though there are some fixes to that. 

My point is that the cost of your 'new' rig may not be just the cost of the transciever. If you had indicated that you had a different budget, or that your operating habits were different, my suggestion would have been different. 

Never used a Jupiter, so can't comment on that option. Probably great for the rag-chew part of your operating, but I suspect that it may leave you short for the contesting and DXing. 

Given the $1800 top of your budget, you can have an Omni VI+ with TT 961 or 962 power supply, all 5 optional filters and a remote 301 tuning pod (a real must). With this rig, you can connect to your computer for logging and rig control. Until you've used that feature, you can't really appreciate how nice it is to have time, freq, etc in the log, or to jump to an exact freq by keying it in on your computer's number pad and hitting enter. The Omni VI is a very easy rig to use. All controls do what you would expect. Very well laid out front panel. Dynamite receiver and legendary TT QSK 

There you've got it. A choice for a rig in the lower half of your budget, and one in the upper half. 

Best of luck with your decision making, and when it is finally done, enjoy the new rig, whatever it is

So the question is "If you wanted a relative simple radio for CW work (use 
is 75% rag chew; 15% contest; and 10% DX)and you had to keep the cost down, 
would you opt for an older rig such as a Corsair II or a software driven 
older rig such as an Omni VI or spring for something in the price range of a 
new Jupiter? My budget is somewhere between $600 and $1800 which rules out a 
number of options. 

Any constructive thoughts would certainly be welcome either off-line or on 
the list. Thanks and 73s
