I see this kind of message constantly, so I thought I would let Ten-
Tec users in on the secrets.
1.To transmit PSK you need an interface between the Sound
Card OUTPUT and the mic or rear audio INPUT. This is
because the output voltage from the sound card is roughly 100
and more times as large as the radio's audio input wants to see.
2.You need to connect audio from the radio to the Sound Card
INPUT. There is no interface for this; it is a wire connection.
You can use constant-voltage audio from the rear of the radio,
the variable speaker output, or the variable headphone output.
3.You need a way to control the PTT. This can be simple VOX,
or you can operate a serial port with the software (if it does
this) and use the line to control the radio's PTT. You can use
command radio control with radios that have this feature. You
can even manually control PTT with a switch, since operation is
much like a rag chew on SSB.
That is all their is. There is no magic. You can operate PSK with
ANY RADIO that operates SSB. You can use your Cosmophone
50, your KWM-1, your Heathkit Apache with the SSB adapter, your
Ten-Tec Omni VI+, your Paragon I or II, your Jupiter, or anything in
between, as long as you have a reasonable audio signal from the
Some approaches automate more of the operation, and you may
find that using a special interface to control PTT is handy, or that
rig control via command is for you, or that you like the constant
output from the radio because there is one less control to adjust,
but you do not need these features for initial operation.
Get your feet wet, reread the software instructions, and then get
BTW, the Zakanaka program, which operates PSK, has a fairly
complete set of instructions.
