[Elecraft] Century 22 vs. K2.

[Darwin, Keith]

All true Jim.  Actually I enjoy the C22.  Yes, it has a direct
conversion receiver but I find the rig's simplicity enjoyable.  RX
performance really isn't too bad at all.  It handles the crud on 40
meters far better than the Century 21.  VFO tuning rate to me is just
right.  I'm an old school guy who actually expects to turn the knob
slowly to tune slowly through the band.

The crowded band issue was obviously due to the DC receiver picking up
"twice" the signals.  Well, that coupled with signals leaking around the
filter producing high freq tones.  But, crank the filter to it's
narrowest setting and most of these issues go away.

And the rig has the key jack on the front!  How totally cool!

- Century 22, just for fun -

In defense of the Ten Tec:

- The Century 22 is a design from about 20 years ago. A lot has changed!

- The C22 was the bottom-of-the-line for Ten Tec when it was made.Lots
of compromises in the design.

- IIRC, the C22 receiver is not a superhet like the K2 or K1. It's a
form of direct conversion, which means you hear both sides of zero beat,
doubling the apparent QRM. All the selectivity is audio, and so is the
AGC. 

- The tuning rate of the C22 is about 18 kHz per turn of the knob.
That's a lot faster than the K2, making the band seem more crowded,
since one turn takes you through a lot more signals.

Both are good rigs.
