There's a way that does not involve any filing or grinding. I've found that the critical gap is the one at the bottom just below the speaker where vibration by the speaker can make the edge of the metal move back and forward, banging against the bottom cover.
That is easily cured by separating the top and bottom (you'll have to unplug the flex cable and battery connector) and then, holding the top cover in your hands with the inside facing you, press your thumbs against the edge of the metal just below the speaker, bending it gently outwards. Repeat and check the fit with the top cover until you have a comfortable gap and a straight edge placed across the speaker lines up with the bottom cover on both sides. On mine, the gap was about 20 mils when the section of the top cover holding the speaker lined up with the bottom cover. The actual gap is not important. You'll know it's big enough when the buzz stops. If you do that, be gentle with the flex cable, and avoid plugging and unplugging it any more than is necessary. Those connectors are not designed for lots of plugging in and unplugging and may become intermittent if abused. 73, Ron AC7AC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
