[Elecraft] [K3] Mixed up FP Buttons

[Jessie Oberreuter]

      VHF SKN activities were interrupted tonight when I switched to 2m and 
all of the buttons went wonky -- some completely dead; others performing 
"unrelated" functions.  When the sanity checks (re-seat boards, re-load 
firmare) failed to make a difference, I started crawling the schematics.
      Pulling the FP off again, I measured across each resistor in the tap 
divider to eventually discover R58 reading ~10 ohms rather than 3k.  I've 
never heard of a chip resister failing to a near short, so I'm suspecting 
its companion, C69, isn't much of a capacitor anymore.  Hopefully, 
replacing one or both tomorrow will fix the problem.  In the mean time, I 
thought I'd check for any wisdom from the list :).  - kb7psg
