[TenTec] Computer Headset Secured -- Now What?

[Rick - DJ0IP / NJ0IP]

Greg, that tip was worth at least a quarter, and so was Barry's, about
buying commercial cables and cutting to size, then soldering the plug to the
radio.  That's how I built my adapters for the AMP and PTT lines.

Having just performed surgery on one of the aforementioned "cheapie" PC
headsets, I offer the following from my recent experience. 

I would suggest making/buying  the adapter box, and NOT doing what I did,
which was cut off the 1/8" plugs, and solder on a new 1/4" headphone jack,
and solder the wires from the mic directly to an 8 pin mic plug.  The wires
inside these cords are "whimpy" and not insulated from each other by any
rubber or plastic insulation. They are instead, like micro-fine motor
winding wires, with a thin, colored, "varnish" that insulates them from each
other. You will need to use heat and liquid rosin (at least I did) to
prepare them to take solder, and then you must be sure you don't have any of
the wrong color in with each other. They are twisted around each other, too,
which helps them be resistant to carrying RF, but makes this job more
difficult. Also learned that even though the 1/8" PC plug for the microphone
has TRS, it only has 2 wires.... I think the T&R are tied together inside
the lug, and the Shield is separate. 

 All this being said, it works well.

And, to reiterate, I would make an adapter box to avoid the above, were I to
do it again.

My 2 cents, and maybe worth less.
