So what you're saying is that the N1MM software is the common thread with the multiple QTH and computer combos?
I presume that it is up to date, along with any OS updates, drivers etc.? What bit rate are you using on the serial line? Maybe try other settings? I've been using HRD with good success and V6 will handle the K3 even better since they loaned on to the author. Juzz sayin' Rick wa6nhc -----Original Message----- From: [email protected] Hi Guys, I've been a happy K3 owner for aprx. 3 years. Regardless which CPU I use, I've always had an occassional problem receiving the error message "VFO A not responding". When this happens while "running" during a contest it presents a serious problem as the computer and radio lock up for aprx. 30 seconds. During this 3 year span, I've operated with a dozen different Windows XP and Windows 7 computers, always using N1MM Logging Software. I've operated from several different QTH's and have the same problem. I always connect via a Serial Port regardless of which CPU I use and have not tried a USB to Serial Adapter. During the past few months, this problem has really increased, such as: during last weekends CQWW Test, I got the dreaded "VFO A not responding" message and computer lock-up at least once every hour. By the way, I do not have a 2nd receiver in the K3 so I cannot say if I'd have the same problem with VFO B. I'd be grateful for ideas on how to eliminate the "VFO A not responding" problem. Thanks & 73, Dick- K9OM ______________________________________________________________ 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
