Re: [IRCA] Rockworks, Oregon Non-DX Report for Oct. 24th

<<<ÂÂ We split up with the idea of comparing the 2 locations. We think 4 has horizon blockage from 300 degrees northward so might not give us some Asians. It does have a better "backscreen" cliff wall behind it. 
Rockworks 2 has no horizon blockage towards Asia. But a bit more signal might leak in from behind with the less imposing cliff wall behind it.ÂÂ >>> 
 
Your assessment of the relative cliff geometryÂisÂvery accurate, Chuck. It would be great if Rockwork 2 had a "perfectly shaped" cliff for Asian reception like Rockwork 4 has for DU reception, butÂits shape isn't nearly so dramatic. We have only scratched the surface in investigatingÂocean cliff transoceanic propagation, though, soÂwe probably still have quite a fewÂdiscoveries in store.ÂÂ 
 
<<<ÂÂÂÂGuy and I have a better impression of Asiatic reception from Rockworks Â4 than you. Perhaps because we have been there in the fall (TP season) while your comments mention July lack of TPs.ÂÂ >>> 
 
AfterÂinvestigating all of the northwest Oregon ocean cliffs from 2011-2012 there was only one that I thought would really perform for Asian TP's-- Cape Perpetua.ÂUnfortunately it is remote, highly exposed to foul weather and extremely cramped for broadband antenna setup (at the Highway 101 turnoff, that is). Rockwork 2 is closer to Puget Sound andÂhas much more antenna setup space,Âbut doesn't offer the same cliff geometry.ÂIf given a choice between Rockwork 2 and 4 for Asian TP reception, though, Rockwork 2 should beÂpreferable. 
 
Of course, when Asian propagation is dreary along the entire west coastÂneither location is likely to meet expectations.
