KX-1 Paddle

The paddle on the KX-1 works loose because the thumbscrew strikes the edge of the circuit board before the paddle body is pulled up tight against the transceiver...There are 2 ways to fix it: (1) grind or file the end of the screw a mite, shortening it so that it does not strike the board, or, (2) make up a heavy paper or felt gasket and glue it to the paddle body where it comes up against the KX-1 case...This will move the paddle body outward a bit, keeping the screw from striking the circuit board...I prefer the gasket because grinding the screw might damage the threads making the screw hard to "start"...Beveling the end of the screw after cutting it might help...

Re: KX-1 Paddle

If the problem is that the screw end is contacting the board, there is
yet another way to correct it - put a #6 washer permanently on the
thumbscrew before screwing it into the paddle body.  I use a light
spring lockwasher on mine.  I would not suggest using an internal tooth
lockwasher because it will tear up the body of the paddle.

The washer reduces the effective length of the exposed threads and the
lockwasher helps keep it tight.
