You're right, most of the failures I've had with projects have been from
misplaced parts or poor solder, but I usually spot them before sniveling
for help. In this case, I spent a couple hours looking at it for part
placement errors, and looked at every solder joint under my stereo
microscope (Ever
I do have to disagree. I consider myself a careful builder and do not often
make mistakes, but even so, for myself, the most probable cause of failure
with an Elecraft kit is an unsoldered connection, so without remark about
the quality of Greg's workmanship, I hold to my statement - 'check

Well, knowing Greg and the quality of his workmanship, I'd doubt that
bad soldering is the problem. Also, his rf test bench is probably on the
same level of, say, Ron's.

Greg,
Congratulations on your early Christmas gift!!! Sorry it is giving you
problems.
Before you start ripping things out or suspecting bad components, remember
that the design does work (and works very well), and that components rarely
fail.
The most likely problem is a poor solder join
My Christmas gift (OK, I opened it early) says "Info 090" when powered
up. According to the manual this is "EEPROM Test #1 failed".
At power up, relays click for a short period, and the display says INFO
