[RTTY] New proposal for a Automated Digital Contest

One option would be to adopt a "mean spirited" approach like Winlink that
says busy frequency detectors are NOT needed.  

However, MMTTY has FFT data available via its API (the data that drives the
waterfall display).  I am not sure about 2-tone.  By having access to the
FFT data, one could make a good decision if the frequency was busy.  I have
some old code written 10 years ago somewhere that interfaces into MMTTY and
pulls in the FFT data using VB6.    If done today, the language of choice
would be C#.

It's not a beacon (a one way transmission) if one is soliciting a contact.
However, to be fair and set a good example, MMTTY and 2-Tone would need to
be extended to provide a "channel busy" signal to hold off CQ transmissions
or automatically QSY prior to a CQ if the frequency was busy.
