Re: Low mic gain, was, show your mic

Whenever you wish to FUND that effort, you'll easily find people who will be willing to get on your payroll!!
If you look at that photo, there's a "clue" in that one terminal connects to the CASE. And the legend that I always saw on the similar photo here: http://www.hfsignals.com/index.php/2017/11/23/wiring-up-the-bitx40/
is also a good giveaway.
This tutorial is another explanatory bit of information (about the first one that popped up in a google search for electret mic pinout) https://components101.com/electret-condenser-microphone
That's ham radio!

Interesting. That picture has no indication as to which is positive and which is negative. If I didn’t already know that the upper right connection was ground the picture would be useless. I am probably offending some people but I’m about fed up. All of the correct information needs to be gathered in one place. Call it a manual or whatever you want but someone who knows needs to take the time and put forth the effort to put it together. And then all the incorrect information needs to be removed from the web.
Not a happy camper.
