As a member of the CRD group , will have to back Mal on this one, the
longer Op modes are quite immune from static , due to the length of the
tx pulses and the non-linear routines in the dsp engine , as its a
averaging system , then 'blips' are not a problem .........yes 100%
noise will lower the s/n level ,
I think it was Mike , who noted the level of decodes during static
where unexpected ......

In the real world of radio there is always QRM, QSB and QRN so let us have
a
meaningful test/result

I would be very interested in the results! Don't get me wrong, I don't
want to know what the *best software* is, I would like to learn what are
the differences using the various algorithms and WHY this is so! It is
obviously, that you are the right person to give these answers. ;-)
