[Elecraft] [K2] RF Board: R115 resistance check

[Giuseppe Sorrentino]

Hy to all, just finished the resistance check of RF Board (K2 #6995) as on page 
62 of the manual. I've dne the check with two gears, an HP3478a and an Extech 
470 (handheld dmm). I have different values as indicated down here:

HP
R115 160 ohms (ref.is >500ohms)
U6 PIN 8  290ohms (ref is >100 ohms)
U4 PIN 16 3,4 K (ref is >1k)
U11 PIN 8 0,7 K (ref is >250 ohms)
U10 PIN 8 5,19 K (ref is >500 ohms)
U12 PIN 1 0,58K (ref is >500 ohms)

EXTECH
R115 3,7K ohms (ref.is >500ohms)
U6 PIN 8  290ohms (ref is >100 ohms)
U4 PIN 16 3,4 K (ref is >1k)
U11 PIN 8 1,1 K (ref is >250 ohms)
U10 PIN 8 230 K (ref is >500 ohms)
U12 PIN 1 2,43 K (ref is >500 ohms)

You all can note the differences between the two instruments, the values are by 
the way between the references given by the manual except the R115 value that on 
the HP is only 160 ohms. I would like to assume that the HP is a better 
instruments than the poor handeld dmm from Extech (excellent by the way), but in 
this case i have perhaps the problem of a bad value of resistance on R115. Is 
there anyone who can makes any comment about these differences and about the bad 
value of R115???
