Hi Dimitris,
 
sorry for that. I noticed my error after I sent out the first mail, my only excuse being that I was pretty much overwhelmed by the fantastic news.
 
Yes I saw that wspr activity is on the upsurge in VK. Stefan and I discussed this this afternoon, and one thought was that keeping split bands might be a better idea. When several stations engage in two-way attempts in the same subband, the receivers will be likely affected by overloading and noiseblanker desensitizing effects. So you might want too consider staying with separate slots.
 
There was some uncertainty whether Dale's 50 W tag was meant to be TX power or ERP. Hereabouts we've sort of settled on stating ERP, simply because radiated power is the relevant quantity for SNR, whereas antenna efficiencies can vary vastly.
 
Best 73,
Markus (DF6NM)

G'day Markus,

just a quick clarification - it wasn't me, it was Dale VK1DSH that
transmitted the famous packet received in France. Since that incident,
we changed our WSPR frequency to comply with the European one and we
will be transmitting as often as we can in order to find out if this
can be repeated! Dale is radiating similar amounts of RF to me, which
I calculate to be around 0.5 W.

73, Dimitris
