[Elecraft] RX architecture

[Benny Aumala]

Yes,
9MHz down-conversion was standard when I homebrewed SS transceivers
in 1960-70. But architecture is also part of its components.
We do not use simple VFO any more, and much has been made to make 
injection signal pure again.
Mixers are much better (we had hot-carrier diode quads). IF DSP is new 
in down-conversion scheme.

And all is for our good.
Enjoy and smile!
