[Elecraft] My KX3 desk microphone project

[Gary - NC3Z]

In my opinion much, much better words should of been choose than 
"seriously misguided", they have connotations that one is an idiot. 
Seriously misguided would be trying to run a 12V device off 120V.

I would of loved to see some data/research/reference as to why this wont 
work, there are a couple of articles (yes on the internet, but this list 
is also on the internet) out there that show that paralleling electrets 
are valid, so I figured I would play around with that configuration. I 
am by no means an expert on microphones and I am not saying I am right 
by any means but my experiment showed that it works, well it shows that 
it doesn't make it worse! I did a lot of on-air A/B testing to make sure 
that my audio was not being screwed up. I continued this path because 
the parallel configuration was receiving better reports.

Good enough, I will correct my error.

That’s all!  It would make no sense for him to make some “wishy-washy” critique of your effort when he knows you are heading off in the wrong direction.  That could be just as confusing.  Of all the people on this reflector, Jim is possibly the most qualified to opine on your effort.  Apparently some of what you were trying to accomplish, and suggesting to others, could be seriously misleading as to the actual result!  I wouldn’t have known any better, nor would a lot of others, but Jim does, and said so.  In effect, all he said is “you are wrong”, but he certainly did not do so in terminology to which you should take offense.

Just be grateful that someone was around, who has appropriate expertise, to prevent your error from becoming an even bigger one!

That’s a big part of the “beauty” of this reflector.  There is a lot of real expertise out there, and I benefit from it regularly.  However, if I say something, and I’m on thin ice in doing so, I need to be prepared to be called on it.  I don’t want to go down a road that has a dead end, and I certainly don’t want to lead others down that same road!  All too often folks tend to take what they read as “gospel” and run with it, so oversight is critical!  If we didn’t have people like Jim Brown participating on this reflector I wouldn’t learn much, and I’d probably be off beating my head against the wall on a regular basis!

I’ve had a lot of fun doing some of that, and using relatively cheap electret elements to revive old microphone housings, etc.  For a few dollars you can duplicate, if not improve on, the results you would get from expensive commercial alternatives.
