Hi Don,
Shorting pin 5 to 4 turns on the 10th LED. I guess my wiring to the front
panel board is good.

Glenn,
As a quick check on your wiring for the LED indicator, short pin 5 of the
output connector to ground (pin 4) and you should see the LED turn on. A
short at this point will not damage the IC - because it is an open
collector output.

Hi Guys,
I put my tuning indicator kit together this weekend that Tom N0SS was
selling. Tom you did an outstanding job packaging the kit. I soldered the
SMD components on the board per the PDF file that Tom provided on his web
site. My tuning indicator does not work. I have 5 volts on pins 1 and 8
on the FSK chip. I have tripled cheked all the connections and the
components on the circuit board. Every thing looks good with my high
power magnifying glass. I am using 500 hz side tone. When I turn the trim
pot on the SMD board clockwise or counter clockwis the 10th LED does not
light up. I have turned it more than 5 turns both directions. I have the
K2 tuned to the birdie at 4.0000 on the 80 meter band.
Can anyone point me in the right direction for further trouble shooting?
Thanks,
Glenn WA7SPY
