Yes Domenico.
That's why I write "From my modest EIRP calculation", becouse there is a few variables that are unknown to me...
Never the less, that eve more huge power... hi hi hi ...

Hi Pavel ,CO7WT
From info received belove by Trevor M5AKA we know that DJ5AR was using a 3m dish (29 dB gain) and 200 watts at the dish feed.
If 200 W is the RF power arriving at the dish feed without losses in the feed line my calculation shows:
29 dB is equivalent to 29 dB isotropic gain so that the isotropic power ratio is 10^2.9 = 794.328 time in power.
The EIRP ( Effective Isotropic Radiated Power) is :
200 W x 794.328 = 158865.647 watt = 159 kW (rounded)

WOW !
From my modest EIRP calculation via the handbook that will be about 129130 W (129KW) (some error included...)
That's a huge power...

Do you know the EIRP used at 1296 MHz by DJ5AR or by PA3FXB
Hi Domenico,
DJ5AR was using a 3m dish (29 dB gain) and 200 watts, PA3FXB also had a 3m dish but I don't know the power > output.
They each have a report on the QSO in the 432 and Above EME Newsletter
