Since you consider yourself as an RF tinkerer, it sounds like an interesting experiment. Since the technology in the K1 predates my interest in Elecraft, probably the up to date inclusions in the Sierra were not available when the K1 was designed 20 years or so ago. The K3 design is not getting long of tooth and the KX3 is the ultimate QRP design from Elecraft. It does not sound like a design change that will make Wayne and Erik any money!

The main difference is imo that the Sierra has a MC1350 IF amp (as has the K2 btw) followed by an LM386, but the K1 seems to do all amplification after XFIL on AF frequencies using LM386+LM380. Could/have the K1 be(en) modified with an IF amp and IF based AGC? Thanks.
