Aside of the "Pickle dipole" did any one have an idea of their setup? (Amp power and # of beam element) A linear amp and the beam stacking is giving the required ERP on the TX side and the 3db stacking gain seems to make the difference between reception just at the noise level and something above the noise. This EME was a good overall satellite station test. 50 watts and one single beam was too borderline to have a decent 2 way contact but without the real Arecibo ERP TX figures it is hard to say if a setup is below standard equal or above.

Thank's Mike
I will now do my maths i have a lot of reference now...But result seems to match the theory a single 24 elements K1FO style yagi beam +preamp and 50 watt was a bit short here.
