Hi Jack,

I recently experienced something similar to your PX3 situation.  When you
said "cold", I immediately perked up.

During winter field day, I decided to take my PX3 with me.  Our club worked
outdoors in about -2C degree weather.  The trailer I was in had a couple of
portable space heaters.  It felt like they were pumping out one BTU each
:-).  By the time I had the station setup, the temp increased to about 9C,
maybe.  It was still cold and I had to wear a coat.  Anyway, I digress.

When I powered on the PX3, the display was dark.  Picked it up to hear the
click of the power on.  I heard a click.  Hmmmm.  I tried a couple of
times.  I disconnected all the inter-connect cables and still no display.
I was a bit cold and had just finished exerting a lot of energy with the
setup (antenna as well), that I just left it disconnected and put it away.
I was a bit dejected, but I had to focus on the task at hand, because WFD
was going to start in moments.  I should have left it turned on for a
little while to see if the display came back on after the internal
circuitry warmed up a bit.  But that never occurred to me because every
other display in my station came to life immediately.

After the PX3 had a chance to settle at home in the warmer climes of my
shack, I connected everything back up and lo and behold, the PX3 display
lit up.  I was quite relieved.  I wrote off the experience to the fact that
the PX3 didn't like the cold weather.  I don't either :-)

Anyway Jack, I am happy to be another voice when you go to Elecraft support
regarding the PX3 display not turning on when the unit is cold.  I don't
know the actual temperature that the PX3 doesn't like.  But I never had
this issue before.  I can turn on the PX3, when in the house, and it comes
on immediately after having sat for days in my basement shack.

Regards,
Brian
