In November, at our holiday home 5 miles south of Torrevieja (Costa Blanca) I tuned in 11023H and had stable pictures on the two HD channels transmitted on this transponder. My receiver is an Eaglebox 800 HD and it showed S/S 89% Q 51%. I am now back in Scotland, near St Andrews, and using the same receiver I am getting S/S 93% Q51% (in the evening) Q 61% (in the morning). The two factors which have changed are location and dish size, as follows:
Costa Blanca: dish = 1.8m Famaval PF, invacom twin LNB, Gain 45db @10.7 GHz, carefully aligned.
Scotland: dish = standard zone two Sky dish/LNB, Gain 34-35db @ 10.7 GHz, not very carefully aligned.
This indicates the 11023H signal is around 10/11 db weaker in the Costa Blanca compared with the signal I am getting in Scotland. Assuming the EIRP of the signal in Scotland is around 50 dbW, the Costa Blanca EIRP should be around 40dbW, which should be receivable on a dish of 1.2m, or greater.
I'm not sure my logic is entirely correct, but it seems plausible.
