Ruben (et. al.):
De ninguna manera, por favor, no use el MicroHAM Router para cambiar la
software en el K3. Sin ninguna excepcion, microHAM no suporta usar el
Router para hacer esto y es muy posible danar el K3 en esta manera. Si
usted utiliza el sistema microHAM Router en esta manera, lo hace a su propio
riesgo para el radio y el equipo de microHAM.
Just making sure everybody understands the importance of what Joe says in
his message.
Here is what I do:
I have a Dell GX280 PC as my ham radio computer. It has one "real" serial
port and 6 USB onboard ports. My K3 is attached to Router using a
Saelig.com FTDI chipset based USB to serial converter. The output of this
converter goes to a $8.00 2 in one out DB9 Mechanical Data switch on port A.
The output of the "real" serial port goes to that same switch on port B. A
short serial DB9 to DB9 cable goes from port C of the switch to the radio.
When I want to use the rig with the microHAM router and the MicroKEYER 2
interface, I switch to port A. When I want to configure the rig using K3-EZ
or the Elecraft K3 Utility, I switch to port B.
I have never had an issue with software uploads or control glitches with
this wiring scheme. Plus, the data switch makes a nice pedestal to mount my
Autek WM1! When I throw the mechanical switch from port to port, microHAM
router recognizes that communication is lost and flashes the frequency
display in the MicroKEYER 2's screen to let me know the radio is not under
MicroHAM control. Switching back to the Router's serial port re establishes
the communication with the MicroKEYER device almost instantly and the
display then shows my selected radio information (in my case, I display both
of the receiver's frequency information. What information is displayed is
selectable in the MicroKEYER 2's configuration tab in Router).
This has always worked reliably here.

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.
