KX-1 Trouble...

[Burke Jones]

Okay gang...I have finished up part one of the build.  I applied power today and all the voltages checked out fine.  The LED lit up, the display worked.... until....

 

I hit the menu button and LED appeared on the display.  Then I tried turning the VFO knob to cycle through the menus, but it would only sparodically change menus.  As I turned the VFO knob, every so often, very random the display would change to another menu item.  Something appears to be wrong.....

 

I can't see any solder bridges, etc, all parts for Part One are installed.

 

I am a complete electronics newbie, but can follow instructions well.  I would love some ideas!

Burke,

Check the soldering on the encoder pins.  It does sound like you have an
encoder problem if some kind - maybe a bad encoder - in all the KX1s
that I have built and repaired (I have not kept count, but it is not a
small number), I have found only one bad encoder, but even though it is
rare, it can still happen.
