[TenTec] Modern version of the Tec Tec Corsair - please Ten Tec!

[Kim Elmore]

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.

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.

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.

Heck, WB6ACU would probably buy a truck load of this radio! It could even be produced – and sold – relatively cheaply.
