[Elecraft] firmware download issue

[Van W1WCG]

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......
