So, the CNC'd K3 tuning knob arrived over the weekend. I's a very very nice piece of work, and regardless of the endless P&M-ing about the price, it's in line with other such products.
But this isn't about knobs, and I'm not trying to start another endless twitter-like thread on the subject, although the subject does seem to be lurking just below the surface of every ham's conscious. It's about inertia. Yes, of course it's heavy and it does spin nicely. At first I wasn't so sure I liked the feel and I went back and forth on the thing quite a few times. But the more more I use it, the more I think it's going to stay on the radio. So back to inertia -- an object in motion wants to stay in motion. And, an object at rest doesn't want to jump up and get going, either (like me in the morning) -- which is where an advantage is that didn't come up in the 4,763 or there'bouts posts on knobs. I like a VERY free running control. The inertia of this thing is such that a little bump here and there doesn't jar the tuning half-way down the band. Well that's a bit of an exaggeration of course, but the point is that even with virtually no friction against the felt pads, a "delicate" touch is not required to keep it in one place once it's put somewhere. Inertia is your friend. I do worry (a negligible amount) about what the increased weight might do to the panel bushing over time, but time is still along way off and bushings are not an endangered species :-) YMMV Grant/NQ5T ______________________________________________________________ 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
