Running the utility trying to access an invalid port should not cause any problems at all, except that you won't be able to communicate with the K3. And invalid or missing port should not cause it to hang in any way.
The first step is to load the Utility with *nothing* connected between the PC and K3. It should run normally except that it can't "talk" to the K3, so you won't get any report on current firmware, etc. You'll see ??? on the Utility screen in those places. You didn't describe your "best efforts to uninstall and reinstall" or what computer/OS you're using, but if you're running Windows that should include removing the program using the install/uninstall utility in the Control Panel, then rebooting the computer *before* trying to install the new Utility. Then, of course you download the utility program again from Elecraft rather than trying to install a potentially-corrupted version already on your HD. I may not have the latest K3 Utility, but the version I have and all the earlier ones offered a way to choose the port from the screens. Click on the PORT tab. If a list of ports isn't shown in the drop-down window, click REFRESH PORT LIST. Normally, if you're not sure which port works, you'd first be sure you have the K3 connected to the PC and turned on, then click on TEST COMMUNICATIONS. If that fails then you'd try a different port. In your case, the K3 is "hung" so it may not respond to a TEST COMMUNICATIONS query. In that case you need to "force" an MCU load as described on page of the Owner's Manual (Rev D). Since you don't know which port is correct, you may need to do that trying different ports until it works.

Hi Pete, I was waiting to see if K6KR or someone more knowledgeable than I was around, but I guess not, so here goes. Run REGEDIT. Look for HKEY_CURRENT_USER\Software\Elecraft\K3 Utility That's where the port (and other) information is kept. I hope this helps. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
