[Elecraft] K2 Construction - 2 Questions

[W2xn@aol.com]

I am still in the Part 1 assembly of the K2 RF board and have a couple 
questions.

1.  Setting the AGC Threshold.  Pg 46 says to adjust R1 for a reading of 3.90 
volts on the DMM.  Turning R1 fully counter clockwise will only give me 3.80 
volts -- I assume this is not a problem.  Tell me if it is.

2.  On the Bargraph Current Test.  Pg 46 says that after you set the GRPH 
mode to BAR the current should be 0.16 to 0.18 amps higher than on DOT.  My 
readings show that on DOT I get 13.8 volts at 0.06 amps.  After I change the 
GRPH mode to BAR, all 10 segments are lit, but a little dimmer that when only 
one or a couple are lit, and the readings I then get are 13.8 volts and 0.08 
amps -- in increase in amps of only 0.02 instead of the suggested 0.16 to 
0.18 amps.   I am using lamp-cord size power cord from a 20 amp regulated 
power supply.  Should I be concerned, and if so, where should I look to make 
a correction.  All other checks are coming out OK so far.

Thanks for the help.
