So now I have THREE BITX transceivers on the operating bench. I've been getting tired of moving the old D-104 around as I change bands. Surely each of these rigs merits its own mic. This would allow me to avoid the hassle of having to adjust the level on the D-104 each time I change rigs.
Fortunately in the junk box I have some useable old mics. An old "Turner SSB+2" mic has been kicking around in there for decades. I probably got it when I was a kid. The element was no longer working, so I just popped an electret element in there, took out the preamp circuit, but kept the adjustment pot. At first I had a 3.3 uF coupling cap in there at the output, but this was letting too much 300 Hz energy through. So I changed the coupling cap to .1 uF and this seemed to even things out a bit.
I know, I know: It is CB gear. It is painted BLUE and it looks like something George Jetson would use to talk to his interstellar Good Buddies. But it was preceded by a very similar mic made for hams (see above). And I like it. It even has the word "Transistorized" emblazoned in script across the PTT bar.
In response to popular demand, "SolderSmoke -- Global Adventures in Wireless Electronics" is now available as an e-book for Amazon's Kindle.
Here's the site:

For shipping from a printer in the U.S. (probably better for N. American buyers) Click here: SolderSmoke USA Version
For shipping from a printer in the UK, Spain, or the USA (probably better for UK and other European buyers)
Click here: SolderSmoke EU Version
The two versions are identical, except for a minor difference in the paper used. That's why the prices are a bit different.
