[Elecraft] K3S stuck on MCU LD - solved
Yup, Everything unplugged from K3S including antennas, and even the mic. When it was plugged into the PC's USB port, it would beep and Device Manager screen would refresh and add a COM port. I received a few direct emails with suggestions. I called CS and was waiting for a return call, figuring it was RMA time. Mid afternoon an email from Don Wilhelm suggested connecting the K3S via its RS232 port rather than its USB, using the appropriate adapters. Worked on the first try! It also appears that the rig's USB port is OK since it communicates with N1MM+ OK. Case solved, though it's still not apparent what the problem was. TNX to all. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] K3S stuck on MCU LD
Don, That state (MCU LD and red TX light blinking) is typical when some glitch occurs between the computer and the K3/K3S during a firmware load. Turn the manual (or read the K3 Utility Help) section on "Force a Firmware Download". Follow those steps and you should find success. If the original error is still present contact Elecraft support. 73, Don W3FPR On 11/14/2019 9:57 AM, Don Pomplun wrote: A few days ago I noticed that when I powered up my K3S (ser #11141) I would briefly get an Err DSE message.

After the front panel LEDs flash briefly, the screen says MCU LD and the red TX light is flashing. Trying this again many times, I get the same message. Then I noticed that with _no power to the K3S and the USB cable between the K3S and the PC unplugged_ at both ends, when I start the K3 Utility, and click /Send All Firmware to K3/, I get exactly the same error message as noted earlier (with nothing connected). Thinking maybe the problem is with the K3 Utility, I deleted it from the PC and reloaded it from the Elecraft site and reinstalled it. Same problem! It appears that even after a long power-down, the K3 processor isn't resetting. Looking for suggestions!

Verify connections to computer. Maybe I’m plug everything but cable to power, computer and ant and try again.

Re: [Elecraft] K3S stuck on MCU LD
Hi, Is the PC detecting the radio when you connect it? Check for the com port appearing when you plug the USB cable in. It will appear in Device manager under comm ports. Make sure its detected and the K3 utility can see the correct port as allocated in Device manager.
