[GreenKeys] RYRY Signal plus Noise for RTTY testing enclosed

[Lester Veenstra]

What would be interesting (usefull),  would be a long file containing a
series of say 6 lines each, of test message and the S/N identity imbedded in
the test message line, followed by a few seconds of mark tone while the S/N
is changed to next increment, and the test pattern repeated with updated S/N
id.   You probably have to post the file somewhere for downloading.  It
should include steps of 0 dB S/N and down ( - S/Ns) , assuming the S/N is
"measured" in a 3 dB bandwidth.

This would provide a self annotating performance "curve" of the S/N vs BER
of the demod.
