Since we're talking about problems with this list in recent threads, the biggest problem is that everyone here is an "advisor", has a better idea, and believes that they are acutely aware of every issue, every engineering challenge every improvement that could conceivably be made, wants a new front panel, new knobs, a 1500W pa built into the new panadapter, rules on what the radio is REALLY supposed to be and (on and on and on) ... And all from everyone's individual siloed perspective -- the radio is this, the radio is that, the radio was designed just for me ... not for you so take your stupid ideas home ... etc., After a while, guys, the constant drone of the "experts" does nothing but raise the noise level, far beyond what even the improved NR in the K3 or the best NR on the planet (aside from the delete key or unsubscribing from the list) can deal with. Maybe the whole list should just sit back and take a very deep breath, listen more, and "advise" LESS! And if you do "advise", don't come here to grumble about how your advice STILL hasn't made it into the radio and how Aptos just ignored your remarkable redesign. About the only thing worth reading regarding the K3 are the firmware announcements and the occasional post from Elecraft. The rest, for the most part, is worse than the effects of a touch controlled lamp sitting right next to the antenna. It's much "quieter" and far more pleasant to just occasionally check the website to find out what's new ...
