[Elecraft] KX-1 Paddle (KXPD1)
I found it very hard to get the screw tight enough that the paddle didn't wobble, on two different KX-1's. Because of the position of the key jack on the PC board, the hole in the paddle didn't line up with the tapped hole in the case. (This was in the left-handed position; I didn't check the other one.) I carefully drilled out the paddle from the KX-1 side, taking care not to drill into the threaded part that keeps the screw from falling out. (Drill the paddle, NOT the KX-1 case!) Then I cut a slot in the top of the screw for screwdriver. A tiny drop of oil on the screw threads, and it works great. 73, Scott K9MA -- Scott Ellington K9MA Madison, Wisconsin, USA k...@sdellington.us __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] 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. 73, Don W3FPR Jeremiah McCarthy wrote: Any ideas on keeping the paddle screw tight?<< Mine seems to work loose easily, Locktite or similar<< would work but I want to remove it.<< 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...
