Hi Alan,

On the webpage they say :
"Both stations used new Wenzel Ultra-Low-Noise 5MHz reference oscillators as the phase-locking frequency references. Short-term stability on the order of 4 x 10-13 is required to keep the signals within a 1Hz filter bandwidth of the demodulating software."
In fact they used QRSS1 (or 1.2 WPM), seems a bit the grey zone between
ordinary CW and QRSS.
It is interesting to note that even at 1 sec/dot a QRSS viewer can dig up
signals that cannot be copied by ear.

Hi Rik the mind boggles a bit when you think of the stability required for
QRSS up there even 3 sec dot mode. Still I suppose it all relative and you
can read QRSS even if it "zips across" the screen, and need retuning.
Freddie was demo'ing SpecLab at one of the recent Martlesham uWave events. I
think he was suggesting it as a beacon monitor.
