I strongly suggest following Don's one cable at a time troubleshooting method.
In my shack the error was caused when I pushed the paddles out of the way so I could place a notebook computer with the firmware files near the K3. After the update, I got the ERR PTT. Felt pretty dumb when I realized I caused it by pushing the paddles into another object. Is your cat taking a nap on top of the key? hi hi Mark AD5SS ______________________________________________________________ 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]
