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.

A few days ago I noticed that when I powered up my K3S (ser #11141) I
would briefly get an Err DSE message. The manual says I should reload
the firmware via the K3 Utility program (like I've successfully done
in the past when a new version is available). But this time when I
click Send All Firmware to K3, I get this:
Elecraft K3 Utility Revision 1.16.7.25
OS Version 6.1 Build 7601 Windows 7
K3 MCU revision ??.??. RS-232 speed 38400 bit/s.
Sending firmware file C:\Users\K2BIO\AppData\Roaming\Elecraft\K3
Firmware\hmcu0567.hex to MCU
/(5-10 second pause, then)/
Error code 0xE2000048: No response to poll while synchronizing to
buffer boundary
MCU verification failed. Reload MCU.
Click "Close" to close this window
I disconnected the Power Pole connector for a few minutes, then
powered it up again. 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!
TIA
