[Elecraft] K3 Woes Continue!!!

[Guy Olinger K2AV]

In doing a forcing a firmware download, you might want to *remove* the
P3 from the circuit. You need to get the circuit as basic as possible.
Connect the PC directly to the K3. Once everything is straightened
out, go back to .

Some folks who have recently converted to Windows 10 have troubles
with drivers for older devices. Sometimes the PC is ultimately at
fault.

Also, USB & serial connections are zonked by purely MECHANICAL
problems, connection loose, pin bent, pin broken off, wire not
actually soldered to pin etc, etc, etc, etc,  ad nauseum. The number
of possible mechanical screw ups on connecting cords is huge.

Another killer can be a conflicting assignment to a com port that
depends on what peripherals are in operation in the PC.

Also, you can have a corrupted download from Elecraft.

Make sure you have the latest version of the Elecraft utility and that
you are saving it to the place referenced by the icon on the desktop.
I've had all kinds of troubles about that since going to W10. It has
changed some defaults. I'm gradually getting all of those changed back
to my W7 settings. There are other ways to get that messed up besides
W10.

73 and good luck, Guy K2AV

> This is Mark Griffin, KB3Z. I am having a problem with updating the K3 Firmware. I have a black screen with MCU LD on it. The TX light is flashing red. My usb to serial port cable is a prolific cable. My computer does not have any issues with this cable. But for some reason the K3 Utility is having a problem where it says attempting to contact K3 and it goes through the various speed settings. I have disconnected the power from my K3 and followed the Forcing a Firmware Download to the letter T but if my computer can't communicate with the K3, all is lost. Right now I have the cable attached to my P3 and the P3 cable is attached to the K3. I have called Elecraft, and waiting for Dave to call me back. Hopefully he will call me. I do not understand why the PC will not communicate with my K3. Why Elecraft doesn't have a button to push to just reset the radio is beyond me. If I sound frustrated, I am! Mark Griffin, KB3Z
