KX-1 buttons
Locked
 
|
Last night I was ready to try checking into ECN-20 with my KX-1 but couldn't get off 40 meters. The band pushbutton simply would not respond. (I did do an ohmmeter check just now, to verify that it is indeed a switch failure and not a bad solder joint!)
I haven't kept track, but if memory serves, this is about the third time I've had to replace a pushbutton switch - my KX-1 is serial number 608 and I built it in April 2004. Has anyone had similar troubles? More importantly, anyone have suggestions on where I might get more dependable switches? I have a circuit board in my junk box with a bunch of snap action switches that I think might fit the PCB holes, but I'd have to find a way to glue the blue button caps on, or rig some sort of substitute. 73 Ray K2HYD KX-1 # 608 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Hi Ray,
I most likely would not have heard you. Band was not happy during ECN/20. 73 and GL, Kevin.

Ray,
It is unusual that you have had multiple pushbutton failures. I repair a lot of KX1s and have never seen a pushbutton failure on my bench. I would think if the switches were not reliable, I would have seen at least one failure. Is it possible that you did not mount the switch body tight against the board? I could believe that a mechanical failure could occur due to flexing of the leads if the switch were supported by its leads rather than the board. 73, Don W3FPR On 4/4/2011 3:15 PM, Albers wrote: > Last night I was ready to try checking into ECN-20 with my KX-1 but couldn't get off 40 meters.
