Hi, One subject I haven't seen touched is the somewhat subjective "does it feel like an analog VFO" (with the 10Hz tuning step) like the old synthesizer? Technically that means fast settling, no overshoots, no skipped steps or resorting to a higher tuning step even when tuning fast. I have never had any problem with this in a real ham radio (IC-718, IC-7200, K3), but my portable Eton E1 is terrible in this regard. It's only use is to walk the street or take in the car for noise hunting. BTW it would be nice to see at least a block diagram identifying the major ICs used.
