He writes "That comes out to be approximately 243,902,443 Million Watts ERP." Since the gain of Arecibo is 60 dBi = 1000000 time in power it is more correct to write 243902443 watt ERP or 243,902443 million watt ERP or 243,902443 MW ERP or better approximate to 244 MW ERP 73" de i8CVS Domenico _______________________________________________ Sent via amsat...@amsat.org.
