Carter,
What do you think of this - one transistor couple of diodes and
resistors which all fit in the computer serial port plug. So I plug
the serial port plug into the computer Com port and the other end is
a straight key (non-stereo) phone plug. Actually that's not
technically true. The Argo V requires a stereo plug but you just use
the shaft and tip, leaving the ring connection empty. You can wire
the rig end as required.
Here is the Link: http://www.qsl.net/wm2u/cw.html
Scroll about half way down and you'll see the circuit. I've seen some
that use even less parts - one transistor, a diode and resistor. But
this one works for me. I used the larger side serial plug housing
(for 9 pin) available at Radio shack and everything fit inside.
There is a Ham who also makes these switch "commercially" in that he
charges about $30.00 each. His are finished a little nicer and have a
phone jack at the plug. So you plug a wire into it and into your rig.
If you are interested I can look up his link. But you can do this
yourself in about 15 minutes and a few dollars in parts.
Good luck and 73,
Paul
PS: The companion program, CWGET, which translates audio cw into text
- and is not free - is also pretty good. I haven't surveyed them all
but it was the best of 3 or 4 I've seen.
Note that as a bonus, the CWType program is free.
