[TenTec] SDR Vs. TT, et al

“In theory, theory and practice are the same. In practice, they are not.”   ~anon.

I am a simple guy, and I think that where the "rubber meets the road" is what matters. I postulate the following: Make a QUALITY digital recording at the station with a GOOD Flex 6700 set up, of an ACTUAL CW QSO with strong signals, at speeds of   xxWPM using QSK. Make sure the side tone volume and the received volume are about equal. Use a recording device SEPARATE from the computer used for  the Flex--- and have the AGC of that recording device is turned off. I think many options exist to do this. Post the results of this file, and a link to that file. WE CAN USE OUR EARS to determine if the performance is up to our standards. THAT is what REALLY matters...... in MY opinion. Do the same from an Eagle, or an Orion, or a K3, et al.......Let's compare REALITY.   - (See leading quote above).

A couple more tidbits as food for thought:

How many top 10 contest finishers are currently using a Flex OR ANAN to place in the top 10 in the contest? (Someone said the 6700 is "Contest Ready" ..... so is my Corsair II, but I doubt anyone is finishing in the top 10 using one  ;-)). 
Did I not just recently read a review in QST where they found 48WPM was the limit of the 100D without character shortening?? (I know this can change rapidly).

Not trying to disparage anyone, nor any rig, nor do I have the ability, or capability, to do any of the above.  I do not know the  answers the questions I posed, but they are the thoughts that ran thru my simple mind on a Monday morning......AND, I am guessing there are those on the list that CAN answer them, AND do the above proposed experiments. I also postulate many on the list would like to "HEAR" the results, not just SEE them.

If I am off-base tell me to go jump in the lake..... I have one close by, and it isn't even frozen over yet!!!

 I'm not sure
 that's the right question to ask because recovery
 doesn't
 necessarily happen in real
 time.  The Flex T/R cw recovery is really a mind
 blower for an SDR.  But does it necessarily
 mean you can do actual QSK and
 hear someone
 else trying to break you in real time?  I think there's
 still
 receive latency so that even with the
 receiver recovering, it still lags
 real time
 signals by 150msec (or whatever).
