Connect K3 USB FTDI cable direct to K3 and try the K3 update again.
It sounds like There is a P3 in there, that needs updating too, and has the piggyback connection across to the K3 with the main connection to P3? In anycase, If it is the later FTDI type usb-ser cable then this program will verify and enable user comport No select on the device; http://www.ftdichip.com/Support/Utilities/Reassign%20COMNo%20Utility.zip Aki ZL1GO reports :- Win7 utility first step - test communications : recognizes Com port and shows com3 speed 38400b. Then move to firmware window: click Check Versions Now---> Attempting to contact K3 ,,,,endless try 38400 b to 4800 b., then connection is lost.. Thanks for all the help. 73, Ken ZL1AIH ______________________________________________________________ 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
