Hi Steve, It may be that USB/Serial adapter you are using for the K3 and KPA500 are the older KUSB that uses the Prolific driver. The adapter that ships with the KAT500 (KXUSB) requires the FTDI driver. Try installing the FTDI driver on your Mac.

I am using a MacBook Pro for shack computer. I am getting the K3 and KPA 500 firmware updates with no problem using this computer. However, the KAT 500 tuner will not recognize the MAC for the initial utility download. I am using the SerialPort 2 for K3 firmware which does not appear when I have attempted to upload the utility program into the tuner. When I attempt to refresh Port List, the Serial port choices do not appear, and the computer and KAT 500 turner (a kit) do not recognize each other. What have I missed, or, have I committed an error in the kit construction. Thanks, Steve KB9AVS ______________________________________________________________ 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 ______________________________________________________________ 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
