I received my tuning indicator from Tom Hammond N0SS last week. I put it
together on Sunday. To my dismay it did not work. I checked and tripled
checked component placement and wiring. It all looked good. I still could
not get the tuning indicator to work. Tom and I emailed back and forth. I
was about ready to send my board to Tom for his evaluation. I got home from
work tonight and started trouble shooting. I got out my trusty Hakko 808. I
put the small long tip on it. I cleaned up all the solder off of all the
components. I then touched up all the solder connections to all of the
components. I plugged the board back into the K2. What do you know the 10th
LED now lights up when the tuning is locked on a signal. I can adjust the
LED to come on and off with the trim pot. If anyone else is having problems
make sure you have good solder joints! Especially the little legs to the
very tiny FSK chip which is the heart of the tuning indicator circuit. They
are hard to see let alone solder. Make sure you have a very small soldering
tip and you get in and out quickly with the tip so you do not over heat
components or lift a trace.
Tom did an awesome job with this little project! I hope this may help
someone else who has or may have problems with this SMD kit.
Thanks,
