That's in the same category as the ten FM transmitter diplexer at Stonehenge Tower in Portland but not all of the stations are 100 KW ERP. In addition to those on the master antenna, there are several FM low power/translator/auxiliary transmitters as well as a few ham repeaters on different antennas on the same tower. Stonehenge Tower itself is a self-supporting three-legged monster, with the coax sewer pipes running up a center 4-foot diameter shaft. The site ground level is 303 m AMSL and the center of radiation of the antenna is 170 m above that. It is a work of art. Our SBE chapter gets up there for a weekend potluck meeting every other August (we go to a different nearby 1000-foot tower site in alternate years). We haven't tested how an Elecraft will operate in any of those fields although one of our members lives in the house adjoining the base of the tower, a former radio studio building. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon Vice Chair, SBE Chapt. 124 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
