Can't connect to my KAT500 tuner via computer. I tried other ports, 2 separate computers, reinstalled all the FTDI drivers & Elecraft KAT500 utility program. I ordered another KXUSB cable from Elecraft, same issue. All the ports are showing properly in my device manager. I can see the light on the KXUSB cable flicker when it tries to communicate. I've been using the tuner manually via the front panel for past few weeks. The biggest bummer is I have port #3 shut off in the tuners configuration. No way to open it manually that I'm aware of.
I haven't changed anything in the shack, just one day it would not connect. I don't see a way to reset the tuner to its factory defaults without the utility program. May have to pack it up & send it back to Elecraft.
Any ideas?
I fired off an email to Elecraft support, see if they answer.
