Ouch! Please visit your USB to Serial adapter manufacturer's driver web site and see if your USB adapter drivers are out of date. If you're using the Elecraft KUSB, the Prolific web site link is in the K3 Utility's Help.
I've heard a few reports of blue screen problems and all were resolved by the current Prolific drivers. The K3 Utility is using just the standard Win32 Serial I/O API, but sometimes responses don't come back when expected, and the CancelIo I need to issue is not handled well by some drivers. This doesn't show up unless there's some other communications problem. If you can, I'd be interested in the event log entry that corresponds to your blue screen event. The event viewer can be launched from a command line with "eventvwr". I'll look again at the code that checks for a new utility version requirement. Maybe the end-of-year wraparound exposed a problem. Please let us know of bugs like this through [EMAIL PROTECTED] as well. 73 de Dick, K6KR -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Van W1WCG Sent: Friday, January 11, 2008 7:35 AM To: elecraft@mailman.qth.net Subject: [Elecraft] firmware download issue Greetings all, and FWIW: Downloaded the new K3 firmware utility v 1.1.1.7 and installed it, and then started a firmware download for the new K3 firmware 1.58/1.48 by clicking on "Send all new firmware to K3". The MCU firmware downloaded OK; the DSP download ran until three bars showed in the progress indicator, and then Windows XP blue-screened, leaving the K3 disabled with a DSP error. I tried this several times and got the same result at about the same point in the download. Then I tried lowering the baud rate of the K3's serial port from 38400 to 9600, and was able to get the DSP firmware loaded, though it took a looooong time. Don't know what changed, but I've done several firmware downloads previously at 38400 and never had a problem. No other hardware/software changes have been done on the PC for some time. Wonder if anybody else has experienced something like this with the new version of the K3 utility? I also notice that while the download is running, the K3 display repeats "new K3 utility required" over and over, but often sending only a few characters and then starting over again. Don't know if this is significant, but...... 73, Van W1WCG ----- Original Message ----- From: "John Hoaglun" <[EMAIL PROTECTED]> To: "Elecraft List" <elecraft@mailman.qth.net> Sent: Wednesday, January 09, 2008 11:10 PM Subject: [Elecraft] XV222 tune-up issues Solved >I figured out my tune-up issue.
