Pretty much the same. I have both radios. The front panel button for XFIL has "Dual PB" below it in yellow on the K3, and on the K3S this was changed to "APF." There may be other nuances.

The reason I ask is that I have a K3S and have been looking for a Nifty Guide for it without success. I was offered a Nifty Guide for the K3 and I am wondering if the two models hand similar operating features since they appear to have the same controls. Thanks for the help. 73, Michael, W1RC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
