[Elecraft] help - firmware hangup

[Bob Cunnings]

In K3 Utility Help, USB to Serial Adapter Troubleshooting topic:

"Before loading K3 firmware through a virtual port associated with a
microHAM microKEYER, microKEYER II, MK2R or MK2R+, change the microHAM
USB Device Router's Radio type to "none". (TU W4TV). If you are unable
to load firmware through a microHAM device, use a USB to Serial
Adapter or a "real" RS-232 cable. Neither microHAM nor Elecraft
recommend loading K3 firmware through the microHAM Router (the PC
software used with microHAM USB devices)."

Maybe this is the problem.

Thanks for responding. Still no joy after going through all the HELP
suggestions. The problem seems to be an inability to connect from the
computer to the K3. Note, this whole arrangement has been working
perfectly up to this point. No cable changes, etc. What I get when
trying to establish a connection to the K3 is a steady hunt through
various baud rates with no success. I have cycled everything many times.
I am not using a serial-USB adapter. I am connecting via a microHAM CW
KEYER [which has been working without problems]. I think I'm getting
desperate! Thanks again.
