I disagree!
With the SX-28 or similar receiver, you actually adjusted the LC tuned
circuits and other parameters yourself. You didn't "request" anything - you changed
the parameters directly.
With the K2 or other processor-controlled rig, you send a request to the
processor, and *it* figures out how to change the LC tuned circuits and other
parameters.
Both systems have advantages and disadvantages. All depends what tradeoffs
you choose.
btw, although the K1 has a processor, it's closer to the SX-28 in basic
design (!).

One thing that I find somewhat amusing is the enoromous attention given to
getting exact QRG down to a few Hz. For specialized uses, that sort of accuracy
might be needed, but I'm much more interested in things like dynamic range,
selectivity quality, etc. - differences you can hear!
