Many years ago, I decided to build the mic preamp that was posted
somewhere on the Elecraft website by Mike N0MF. I believe it is still
there. It boosts the signal from a Heil Proset dynamic element up to a
level sufficient to drive the K2/VOX. Since that time, I believe Heil
has produced a special element that does away with the requirement for
this preamp. Nonetheless, I built one and even designed a simple PCB to
hold the 8 parts. The board was so small that I made a couple while I
was at it. Not having any need for two of these preamps, I've had the
2nd board sitting around, gathering dust all these years. I could just
throw it away (it's unpopulated), but before I do that, I'm offering it
(board only) to anyone who wants it, free (tis the season). It does not
come with any parts, but an enlarged picture of the PCB will be included
with it, showing the parts placement. The board is small enough to
easily fit inside an old 35mm film can (remember those?). I'll gladly
send photos of the board and the finished product to anyone interested
in seeing how it looks. I'm NOT giving away the one I built, just the
spare unpopulated board, of which I have only one (1).
That being said, the first person to request this board gets it (no
foreign addresses). If nobody requests it, I'll go with plan A and
pitch it. Please reply to me, rather than the list, to cut down on list
traffic and to make sure I receive it, as I only get the digest version
of the list these days. and don't always read it end to end.
Thanks and 73,
John AA0VE
