Hello Richard: According to my records, there have been only 4 utility file changes since your version FW242.
FW Utility 2.42 1.1.6.3 2.72 1.1.10.17 2.80 1.2.1.6 3.11 1.2.3.18 Version 1.1.6.3 would be compatible with your configuration. A suggestion for ELECRAFT might be, put these 4 files in a separate folder called /util/ and could be accessed by: ftp://ftp.elecraft.com/K3/firmware/util/ Since the names only have meaning relative to FW release, they could have names like util242, util272, util280 and util311. The correct Utility file could then be available to everyone, for whatever reason. IMHO, go ahead and upgrade. The risk is low. If the current Utility program recognizes the K3 and the COMM test works, you should have no problem. After upgrading, I also recommend the K3_EZ utility to give you a more visible view of your new configuration. See ELECRAFT software page for lots more goodies. You have entered the computer age with your Software Defined Radio. Enjoy! 73's Tony K2ZLS ______________________________________________________________ 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
