RTTY connection?

[n8ewy]

Is it correct to assume that you must make up two jumpers in order to
connect RTTY?  1. One to connect audio output (from which jack?) on the K2
to the Mic connector on the sound card, and 2.,  One from the speaker out
connector of the sound card to the Mic jack of the K2?

 

I have the proset headphones connected to my K2. I do not use the large ¼”
with 1/8” adaptor for anything.  The large ¼” portion of the adaptor, which
came with the 1/8” insert, seems to serve no function.  I plug the headphone
jack of the headphones into the headphone jack of the K2.  That is the only
way I seem to get the headphones to work.  I plug the gray 1/8” plug from
the headphones into the smaller 1/8” standalone jack in the adaptor in the
adaptor which came with the proset and that is the way it seems to tx when I
key the keyer.

 

My question is:  If it does indeed require to jumpers from the soundcard,
where do I connect them to get RTTY to work.  What portion of my proset
headphones connectors should not be connected when I achieve this?

 

I am using HRD and have been trying to use the PSK31 portion of the program.
I also have “digipan” loaded on my computer and was going to try this
program as well.  I am open to any suggestions for a RTTY program.

Dohn,

Goggle on RTTY and you will find lots of links.
http://www.dxzone.com/catalog/Software/RTTY/ has a listing of several
programs that are usable for RTTY.

The soundcard/computer connections are the same as that used for PSK31, and
can be either a simple set of connections or be rather complex.
http://www.psk31.com/Hook_it_Up/hook_it_up.htm has links to several articles
dealing with the interfacing - http://www.qsl.net/wm2u/psk31.html shows
interface techniques ranging from super-simple to medium complexity.  I
recommend salvaging a couple transformers from defunct PC modems to use in
the lines to the soundcard and either a transistor or optoisolator to detect
the serial port RTS (or DTR) signal for keying the transceiver.  The
optoisolator allows the computer and transceiver grounds to be separated.

The mechanical/electrical connections between your computer, proset and the
transceiver are of your own choosing - there are many combinations that will
work, I prefer to use a switch between the soundcard interface and the
mic/headphones and I have built that into my soundcard interface box (my mic
plugs into the interface box, but that is my choice).
