Don't attempt to load firmware into your K3 through a microHAM device. Use a USB to Serial Adapter or RS-232 cable that sends exactly what is sent by the K3 Utility.
Some users have sometimes succeeded by changing the microHAM Router to a radio type "none" before loading K3 firmware, but sometimes (depending on the microHAM router version) that doesn't work either.

At first my PC 'sees' the K3 but during upload something went wrong and now I have a K3 displaying MCU LD and a blinking TX LED. Anyone has a lead here? vy 73 Eric PA3CEV _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
