I look at the K3 as a "middle conversion" design. With the 8.215 MHz IF; 160M, 80M and 40M are up converted and all the others are down converted. It works very well. For a real down conversion radio, consider my old Hallicrafters SX-99. Everything is converted to a 455KHz IF which includes a crystal filter (I think one poll). It really doesn't do very well on image rejection. :-) Cheers - Bill, AE6JV --------------------------------------------------------------------------- Bill Frantz |"Web security is like medicine - trying to do good for 408-356-8506 |an evolved body of kludges" - Mark Miller www.pwpconsult.com | ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
