[Elecraft] [K1] RF Board Resistance Checks

[Bob Molloy]

Hjalmar & Don,

 

Thanks very much. I’m sure that’s the right answer. It must be, it’s the one
I was hoping for.

I remember when I built my K1. The manual said > 1K ohm meaning infinite, or
< 5ohms meaning 0 ohm or shorted connections. Made me confused. I think as
long as it confirms to what the manual says it's ok.

Hi,

 

I'm up to page 29 in the manual and doing the first resistance checks on the
RF board. I have problems with these 4 test points:

 

P1 pin 16

P1 pin 17

U4 pin 6

U4 pin 7

 

My DMM sometimes shows resistance on these points, then it climbs until it
indicates an open. Sometimes it just shows infinity. I've checked for solder
bridges, unsoldered pins, etc. Actually took pictures of the top and bottom
of the board so I could look at them full-screen on the PC. (The pictures
are here: http://www.kd2uj.com/Telegraphy2/default.html)

 

The other 9 test points seem to be OK.

 

The meter is an "Equus 3320 Auto-Ranging Digital Multimeter." Bought it on
Amazon.

 

Can anyone help?

 

Thanks,

Bob
