Never perform a firmware upload to *any* rig with a microHAM interface.
Every microHAM Users Manual specifically states the interfaces are not
to be used for firmware uploads. There are several reasons for this -
some rigs require direct manipulation of RTS and/or DTR to control the
upload process and microHAM does not support that or in the case of the
K3, the radio resets itself in the middle of the upload process which
causes a reset of the communications data parameters.

Like many other "RS-232" control ports, the K3 does not like signaling
voltages much less than +/-10V. Many newer USB to serial adapters are
being designed for "low power" operation which typically means +/- 8,
5 or even 3.3V signal levels. Measure the voltage on each of the
pins of your USB to serial adapter and make sure it is not a "low power"
device.

Rudi,
I had similar issue running the firmware upgrade through my MicroHam microkeyer
USB router. I am not sure if you are running your cable direct or through
another system with virtual comports. Virtual comports seem to have issue with
the firmware for the K3.
I didn't see if you mentioned anything but a direct connection but I thought I
would bring up my similar experience.

Rudi,
Did you look at the chart of error codes in the back of the manual and tried
the correction steps given for that error? That is the first step.
For ERR DSE, the correction is to reload the DSP firmware. If you tried that
and obtained the same error, download a new copy of the firmware from Elecraft
and try again.

Dear FM,
The upload for the new firmware makes me crazy.
I get error after te DSP 02.81 version.
2 errors:
ERR DSE
ERR PL1
I noticed that the menu has strange letters but this is due to the fault
upload from de DSP firmware.
I tried different pc and have the latest version of the USB adapter.
