I didn't do this with a Corsair, but I did try it with my Kenwood
TS-930S, all with headphones. I matched the CW pitch and adjusted my
Orion II CW bandwidth to the bandwidth of the Kenwood (400 Hz). I could
tell the difference but it was very subtle and best described as a
softer sound on the Kenwood, likely because the filter skirts are not as
steep as with the Orion II. I should try this on SSB -- I simply
haven't, yet.

Well the K3 sounds just a wee bit better than cr@p, at least when on its
internal speaker.
It would be interesting to see a youtube video comparing a Corsair II to an
Eagle.
How much difference is there in a pure analog signal and a modern DSP radio?
My best friend has my old Omni (A) from 1979.
I will try to borrow it and compare.
May take a while, though.

In concept, this is a nice idea.
But... could Ten Tec actually build that radio, today, with available components, and be able to affordably sell it? If they could, would there be enough of a market to buy them?
If it weren't for a couple of things, I'd be interested in a potential 2014 "Corsair III".
Those couple of things?
(a) I'm still paying off my Omni VII
(b) I have this gorgeous Corsair II sitting in the shack. (It would look a
lot better if I had the Corsair II RVFO, not the Corsair one, but you can't
have everything!)

G’day
For the last month or so I’ve replaced using my modern Elecraft K3 (digital
signal processed back-end) and High Performance Software Defined Radio (digital down
conversion at the antenna socket) for day-to-day operation with a Ten Tec Corsair II.
Reintroducing my ears to the delights of entirely analogue radio – with what to them is probably the best
sounding analogue radio they’ve ever experienced – has given me an idea about what Ten Tec could do
to differentiate themselves from today’s other ham radio manufacturers – and make themselves a lot
of money and friends.
The two Corsairs models are approaching their 30th birthdays and diminishing in
their numbers and serviceability. However, more and more radio amateurs are
looking to purchase one for their classic simplicity, kick-ass QSK and
easy-on-the-ear analogue sound, which can be considerably improved by carrying
out the modifications detailed by Barry N1EU on his Corsair wiki. Put in a N4YG
DDS VFO and then you have a transceiver with a two VFO and split frequency
capability.
What about Ten Tec going back to the future and producing a 30th anniversary version
Corsair, incorporating the above? No digital signal processing whatsoever –
just sound, classic analogue engineering. Keep the basic Corsair architecture but have
a switchable 2.8/500Hz filters in the 9MHz IF and follow these with 2.8/500/250Hz in
the second IF. Keep the wonderful audio/hang AGC (or put in Omni-6 IF AGC and add the
G3TXQ hang AGC modification) and use OPA2134 quality op-amps in the audio chain. The
basic design stays but modern components would be used.
Totally keep the Corsair I look – dark grey front panel with four big red digits and one
green one for the smallest number of Hertz and an analogue ‘S’ meter. This is truly
the BEST LOOKING radio ever!
No memories, no keypad, no menus – just a great, basic analogue ‘Harley Davidson’ radio/easy chair aimed at
us ‘old school’ guys and the increasing numbers of young ones who buy vinyl records and appreciate classic cool.
Heck, WB6ACU would probably buy a truck load of this radio! It could even be produced – and sold – relatively
cheaply.
If you think this is a good idea, write to Ten Tec and let them know what we’d
like.
