On page 29 of the K1 manual is a list of resistance checks for the RF
board. All of my values check out except one. I have completely
checked all of the parts on the RF board for placement and value twice
and everything is correct. All of the solder joints look clean.
U3 pin 3 207K this should be < 200K
U3 pin 5 > 20M
U4 pin 3 102K
U4 pin 6 > 20M
U4 pin 7 > 20M
My U3 pin 3 reading is 207K when it should be under 200K. Is this close
enough? Can anyone advise where to look for the problem? It seems odd
that U3/5, U4/6 & U4/7 are so high when >10K, >10K and >1K are listed
respectively. Did I fry a component?
Thanks,
