John in the K3 Utility Help file it explains what to do, it's under troubleshooting - Force K3 into firmware load required mode
Hope that fixes the problem... 73 Dave, G4AON K3/100 #80 (f/w 3.68) ----------------------------- I attempted to update my K3 to version 3.68 and now my K3 no longer works. It was working fine. I updated to version 3.67 yesterday. I tuned the radio on just now. It was working fine. I downloaded and extracted version 3.68. I opened the K3 Utility. The utility read the K3's firmware and saw that the 3.67 MCU file was newer. I clicked on "Send all new firmware to K3". The K3 screen said something like MD D. The utility said something like D didn't echo, remove power. I couldn't turn the K3 off, so I removed power. I reconnected power and turned on the K3. Now the red TX led flashes slowly and I can't turn off the K3 without removing power. Now what??? 73 de K1ESE John ______________________________________________________________ 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
