Hi, I also have an early s/n KX2, 024X. I had the same problem of the bowed Plexiglas cover. My cure was to grid off 1/16th strip on each end and elongate the screw holes carefully. No more bowing.  GL 73 Jim H K7SSS  In a message dated 8/24/2020 4:34:59 PM Pacific Standard Time, n7...@arrl.net

Well at least the bugs were external! Thanks Wayne for the information. I’ll try flipping it around and I’ll check with customer service if it’s still an issue. Mine was a fairly early one so the change could’ve happen later. Usually a gentle puff of air under the cover is enough to get the

Hi Dan, Flip the bezel over when you reinstall it. This will compress the convex catenary side against the case, reducing the gap. Note that at some point in the KX2's history we revised the bezel, moving the screw holes slightly outward. Customer support could help you determine if you have

I highly recommend you run a power lead to the battery (ideally) or the main power bus in the car interior rather than tap off the limited accessory socket. Keep well under the fuse rating that feeds the accessory plug if you go that route. Steve WM6P

Of course it applies. Mother nature does not pay attention to what we CALL things. It is quite common for DC and mains power to carry AF and RF currents. That's how most noise is radiated -- as a common mode signal on cables connected to equipment that includes noise sources. BTW -- as
