Hi, Bob: Yes, I have learned about that one since posting my comment! I tend to forget that controllers today can do things that were not practical a few years ago. Stuart (I think it was) pointed out that Art Collins actually accomplished passband tuning by mechanically rotating the whole oscillator assembly in one of his designs.
All of these approaches add complexity. Complexity isn't necessarily bad, but it's almost always more expensive either to design or to reproduce. Ron AC7AC -----Original Message----- Hi Ron "One of the strengths of the K2 is its single-conversion design. That is, in part, responsible for the extremely good specifications the receiver enjoys. However, i.f. shift such as other rigs often feature require a multiple-conversion design with all the issues that come with additional mixers, oscillators and complexity. " Well, I'm not sure this is totally true. Before I got my first K2, I used a Kenwood TS-180S which had a very nice IF shift feature. It was also a single conversion radio, with an IF of about 8.3 MHz. I loaned the manual to Eric and Wayne so they could see how it was done. Sure wish there was a way to implement it in the K2. 73, Bob N6WG The Little Station with Attitude _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
