[Elecraft] K2 kit build problem

[Don Schroder]

Ok, I’m confused. But I have an excuse (I’m old). I remeasured and both pins were > 20K! Problem solved it’s self.

I should have known that touching the probe tips would change the resistance, because I have a lot of resistance especially
When the wife “tells me” tp do something! I also played taps at gravesites for three years while in high school.

Thank you all for your kind words. I’m excited. A great radio (K2), a great reflector, and great friends a-coming!

So, no problem so far (Yea !!!!).

Hello Don,

Welcome to ham radio and to the Elecraft Family.  I am not an official or employee of Elecraft.  Watch for an answer from Don, W3FPR.  He is an official Elecraft repair guy and he knows what he is doing.

I don't want to insult your intelligence or experience, but I have to ask that you make sure you are not touching the metal parts of the probe tips when you make these measurements. Your body resistance will lower the readings, especially if they are supposed to be more than 20K.  Also, look for solder bridges or splashes that aren't supposed to be there.

This is a great reflector and someone will have the answer.  I built a K2 in 2004 and it is a great rig.

I am 76 and an retired Electronics Engineer.  I was in the Navy from 61-65 as a CT M brancher.

I am associated with the local chapter of the Marine Corps League as I play TAPS for the military honors at graveside services for veterans.

Sempre Fi!

Greetings!

I am new to ham radio. I studied and passed the “extra” class. I am now building my first radio, a K2. This is my first post to the reflector, too.

I am on page 38 of my build (serial 7818) and just completed the resistance checks. Two of the test points have a lower resistance value than suggested.

U1 pin 4 measured 15.06K, should be > 20K
U1 pin 28 measured 5.06K, should be > 20K

I’m heading for the schematics to debug. Any suggestions on where to look would be greatly appreciated!
Thanks!
