Re: Firmware upload problem

Setting "No radio" does not guarantee transparent operation
by microHAM Router.  Again:  

   DO NOT PERFORM A FIRMWARE UPLOAD USING MICROHAM ROUTER
   WITH ANY MICROHAM INTERFACE.  NO EXCEPTIONS.  

Even though I know my way around Router and the microHAM
interfaces well enough to generally make sure Router is
transparent, there is no way to force and lock the data
rate between the microHAM interface and the transceiver.
I keep a serial cable attached to a serial port on one of
my computers specifically for use when updating K3 firmware.

73,
