Your ERP is slightly below 100w. That would be very low if this\nwere AO-40. I ran 10w at antenna with 20-dBi gain for ERP 0f 1000w for\nAO-40 amd way marginal (one s-unit above noise floor). I have no info re:\nAO-51, so will have to wait for that.\n\n73's Ed\nPS: When I get tower back up, I will be able to run 20w to two lloop-yagis\n23-dBi for ERP of ~4000w!\n73's,\nEd - KL7UW \n=========================================\nhttp://www.qsl.net/al7eb - BP40iq \n144-EME: FT-847, mgf-1801/1402, 4xM2-xpol-20, 170w\n432-EME: FT-847, mgf-1402, 1x21-ele (18.6 dBi), 60w\n=========================================\n\n", "attachments": [] }
