[simpits-tech] Adapter Boxes

[Brian Sikkema]

Well, Jay, if I can find a cheap source of parts, and I'll soon have the 
test equipment to play with, I should hopefully be able to set a box up to 
convert straight from military to PC - or any of the other variants out 
there. Its gonna take some work, but I've got so many EE's and equipment 
around here, I'm sure I can get it done. I just need to find the parts.

I know I got it to work with my HGU-55 and MBU-20/P helmet and mask.  I had
to buy a military to general aviation plug (that wasn't cheap).  I then
built me a little box based on Brian's schematics and then got some patch
cords from the box to the sound card and bingo, it worked like a top.

Problem is Brian, is that you can't just convert the plug, you have to
convert the impendence as well.  The circuit I looked at with the cord I
bought was pretty simple and I would think too hard to make.  I did have a
problem in that inside one of the plugs was a teeny-tiny coil and one of the
wires had come undone.  There wasn't much wire to work with and I had to
resolder them back on.  It works fine now, but if they come undone again, I
don't have any wire left to play with and will have to do a patch job.

Hi:
I have a Flight COM head set that I use for my flying. I will be willing to
play guinea pig,  but as long as my set isn't damaged so that I can't use
them.
