 You can also enter fractional
numbers, and (at least on my German computer) the separator had to be a comma
(e.g. 0,25), not a dot (0.25). The TX multiplier can be set to less than 1
giving narrower bandwidth, however there is no way to change the receive
channel spacing.

It's quite possible to have Jason transmitting and watch it's audio output on
Argo, both running simultaneously on the same computer (P II 233 MHz). You
only have to stop Argo before receiving with Jason.

Hello Markus,
   the TX multiplier is meant to compensate for a TX that converts the audio 
output
of Jason to the desired frequency, performing in this process multiplications
(or divisions) that would otherwise alter the natural frequency deltas used in 
the coding
scheme of Jason. So there is no need for an equivalent adjustment of the receive
channel spacing.

The need for a dot or a comma as fractional separator is dictated by the 
settings of
your Windows installation. Germany (and many other European countries) uses the
comma, while UK and the States use the dot.
If you haven't noticed yet, also the time of the day displayed by Jason uses the
24- or 12-hour format (complete with AM / PM) depending on the country you are 
in.

If you use a sound card which adheres to the AC97 standard, you can have 
multiple
applications using the sound I/O simultaneously. In such case you wouldn't have 
to stop
Argo before putting Jason into receive mode. Quite useful for testing....
