Hmmm. I was originally suspicious of that figure, and have seen nothing yet
that supports it. I am not aware of any amateur radio WOLF reception so far
that would not have been viable using QRSS, but the technique is at an early
I am still keen on WOLF on the promise that it can produce results from a
relatively short peak in conditions, whilst QRSS/DFCW needs a longer period
of enhancement. The really big peaks - the ones that would allow you, for
instance, to get through - last only a few minutes. Even if it is no better
dot DFCW, it may be an improvement in terms of time. This time factor was
identified this winter as the greatest barrier to regular two-way
Also, I am not suggesting that the carrier should provide anything readable,
merely showing that a signal is there. This could be well down on an 'M'
I remain skeptical but fascinated.
