[Elecraft] K2 kit build problem

[ab2tc]

Hi Don,

I know this is OT, I apologize. I have at least three of the bright yellow
meters from Harbor Freight and I love them. I have checked them all against
NIST certified meters at work and they are all accurate to all digits shown.
Not bad for a 3 to 6 dollars (or 0 as you indicate) instrument. In general I
am skeptical about most of Harbor Freight's offerings, but this one is a
winner.

Don,

I am glad to hear that you solved your problem.
Some DMMs (but very few) reverse the polarity of the red and black probes.

I trust you were using a modern DMM as opposed to an older VTVM or VOM. 
Those older meters have voltages when measuring resistance that will 
turn on semiconductor junctions.
If that is what you are using, get a proper DMM for the K2 and any other 
semiconductor project.  The inexpensive (or free with a coupon) DMMs 
offered by Harbor Freight are adequate for your measurements on a K2.  I 
have 4 of them in various places for when I need a quick reading.  If I 
need real accuracy coupled with speed of response, I use my expensive Fluke.

73,
Don W3FPR
