[Elecraft] [K3] K3 firmware 2 years on and still much to do

That has little if anything to do with it.

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 ...
