I guess my WW-II vintage BC342 receiver (that I started with and still own) was 
"advanced".  It has an extensive gear train for tuning.

On the other hand my two Elecraft K3s are full of DDS and microprocessors but no 
variable capacitors.

Flex radios, are direct sampling SDR and newer ones offer GPS stabilization.
