[Elecraft] FW: New CW audio recording: K3 vs. K4D

[Morgan Bailey]

Armchair analysis, not having the radio in front of the equipment, taking a
compressed audio file and staking a claim...this is sadly funny. Go to
Eham.net and look at the same thing by people who believe themselves an
authority on smoke signals.

I'll wait for my 2 K4's to arrive. I know I will be quite happy. The radios
are feature rich and will take a learning curve. What makes a good/great
radio is not just what the equipment on the bench reads out or measures.
There is ergonomics, ease of operation, asthetic beauty, technical
electronic construction and design that make the total package. For
instance, Flex radios are plagued with problems in software, drivers,
memory cards, multiple error messages, failure to boot taking 45 minutes to
get the OS working properly, and besides, they are one of the most ugly
radios on the market. People still buy the 6600M and use it for contesting
even though it does not score in the top ten on Sherwood tests. Contests
are still won every day with radios that are 30 years old and with new tech
that  are plagued with problems. If you want a stereo, then go buy a stereo
and leave the audio analysis to the audiophiles, besides I doubt your ears
are that good at any age. If one was an orchestra Maestro, then maybe this
might be true but for the average ham, these clips sound great. There are
known problems with the audio recordings like RF getting into the MK2R+.
Now there is an area that Elecraft could surely work on and make their own
seamless interface to the elecraft line for SO2R operation.
