Thanks to everyone for your suggestions, I tried them all. After additional sluething, I believe our K3S has an issue with the KIO3B board. The USB Audio CODEC will not load or be recognized on any computer (CAT control works fine and is recognized in the Elecraft K3 utility).
Additional testing: I tested other devices on our club PC. It quickly recognized the USB Audio CODEC for an IC7300 and mini external sound card. I then tried my personal K3S....and it quickly recognized both the USB VCP and the Audio CODEC. Next I attached the club K3S to my personal PC - same result as with the club PC, it was not recognized on my computer either. I then tried reloading the firmware (again). No change. My conclusion is that there is an issue with our club K3S. I will have to call Elecraft support to see if there is a way to address the USB audio CODEC or if the KIO3B must be replaced. -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ 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]
