[Elecraft] Problem with first test KX1

Hello All

I'm on Page 28 of the manual. D1 lights and the LED is OK. However  
when I start to do voltage checks,  I get  results that are nothing  
close to the manual. Now granted, I'm using a Radio Shack DMM (!)   
which is flaky and inconsistent, but when I get good contacts it  
shows that the supply voltage at both ends of D2 is OK. The other  
readings on D2 and U1 bear no relationship to normal. For example on   
U1 pin 1 I get no voltage.

Could be the DMM of course, (I've sent away for a Fluke), or my lack  
of expertise, but I'm stopping until I get this resolved.

Should I be taking these readings from the top or bottom of the PCB -  
I've tried both ways.  By the way, which is pin 6 on U3?

All solder connections look good.


TIA,

Jeff KG6ZVT
