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......

Subject: [Elecraft] XV222 tune-up issues Solved
I figured out my tune-up issue. After some pondering, checking that all of
the pieces were in the right spot and looking at the data about the test
points in the back of the book I figured out that I needed to tweak R39.
Once I did that I started getting RF output and then the rest of the tune
started working MUCH better. R39 need to be adjusted higher than the 20mv @
TP5 that is listed in the book. That was the magic for me.
I will be wiring it up tonight into the station so that I can try to get
it tested on the air tomorrow night.
We are a little over a week from the Jan VHF contest and I am still
building things.
