[Elecraft] K3 Assembly, Resistance Checks

[Ron D'Eau Claire]

All are good. 

 

The next rev of the assembly manual reduces that 50K ohm value.

Greetings,

 

K3/100 assembly in work.  I just did the four resistance checks that verify
the power buses are not shorted to ground.  All R measurements exceeded the
minimums specified.  However, that kind of leaves a big range of what
constitutes "nominal" values.  Can anybody provide what are typically
nominal values for these?  Below are what I measured on my particular K3
with respect to minimums required.

 

1. 12VDC IN connectors.  Required: >50K ohms   Measured: >20M ohms (out of
range)

 

2. Between R36 (test point) and ground.  Required: >150 ohms   Measured: 234
ohms.

 

3. Between U12 (test point) and ground.  Required: >500 ohms   Measured:
4.8K ohms.

 

4. Between U13 (test point) and ground.  Required: >150 ohms   Measured: 423
ohms.

 

Thanks much.  Any advice appreciated.

 

Walter, N0DZJ
