It is possible the parameters set in the computer after reboot don't match those set in the program. Check the port and baud settings.
Generally xom port settings need to match for communication to occur.

After restarting the PC, suddenly I cannot communicate with the radio using DX Lab Suite or N1MM+ on the assigned COM port. I have downloaded the K3 Utility software and it is able to connect to the radio on COM5, its usual port, and invoke macros via the Utility. So I know there's proper communication between the radio and the PC. But once I close down the K3 Utility program I get the first major problem. The radio goes into transmit for 10 seconds, releases for about 4 or 5 second, and goes back in to transmit. Only powering the radio off and back on again stops this behavior. The main issue is that no CAT control software seems to be able to connect to the radio at all. The radio is on COM5, and has been for at least the last 4 or 5 years, and until today it has just worked, even after building a new computer last November. I just rebooted today and everything went to heck. The kicker is that's it's not a K3 hardware problem, and since it works with neither N1MM nor DX Lab software any more it's apparently not those programs either, and quite frankly I just don't know where to look next. Compounding the issue, and likely related to it, the N1MM Rotor control cannot find either COM port assigned to the rotors (COM1 and COM3). I have tried removing the ports and re-adding them in Device Manager but the problem still persists. I am absolutely prepared to pay a certified systems professional to diagnose and fix this, but with ultra-specialized radio gear I doubt they'd be able to figure it out either. Any suggestions? I'm basically QRT until I can fix this. ---------------------------------------------------- Regards, Peter Dougherty, W2IRT DXCC Card Checker/CQ-WAZ Checkpoint www.facebook.com/W2IRT<http://www.facebook.com/W2IRT> ______________________________________________________________ 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 Message delivered to [email protected] ______________________________________________________________ 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 Message delivered to [email protected]
