[Boatanchors] Radio Shack Crystal Mic elements

[Glen Zook]

The specifications are pretty much the same as the
elements that Mouser sells (part number 25LM022). 
Those particular elements work very well with "boat
anchors".  In fact, I put one of them in my "boom"
microphone that I use with my 2 Collins S-Lines, Heath
SB-401, Hammarlund HX-50A, and a couple of other
transmitters.

Comparisons with a D-104 that has a pretty new Astatic
element (got it shortly before they discontinued the
D-104) the stations contacted say that the audio is
either about the same or that the Mouser element
"sounds" a little better.  

There is plenty of output from the element to drive
the boat anchor transmitters.  Therefore, since the
Radio Shack elements have pretty much the same
specifications they should work fine.

I thought I'd "ping" this list to see if anyone
remembers them or better still used them, say, in a
D-104 or similar mic.

Not much in the way of specs on the container except
that they have a frequency response between 100 and
5kc......... And, that the sensitivity  is -56db, +/- 3db.
