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....
