[Elecraft] KX1 ATU - Alignment & Test

[Burke Jones]

Okay, I have assembled the KXAT1 ATU for the KX1.  I got it installed into
the rig tonight and I am working on the "Alignment & Test" section on Page 7
of the manual.

I did preset R1 & R2 per the errata picture.

Everything went fine until I started adjusting C9 for the lowest possible
voltmeter reading.  I have a MV scale on my DMM.  The first problem I
noticed was that when I entered the TUNE mode, my display showed P0.0 with a
12.4V power supply.  I adjusted C9 to give me .2 mv on my DMM - the lowest I
could get.  When I canceled TUNE MODE it showed r1.0.  I was running it into
my 50 ohm dummy load by the way.

Should the display show something other than P0.0?  Sometimes it would
briefly show P0.1 - but on for a split second.

I could hear the signal being transmitted into the dummy load on another
receiver - so it is transmitting.

Any thoughts?
