[Elecraft] MCU LD

[Dick Dievendorff]

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.

   OK,
   I  tried  to  load  new  firmware  to the K3, not using the USB-serial
   cable, but thru the micro keyer interface which is normally connected
   to  the  K3.  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?
