I operated SOLP from Wayne N6NB's home station (thanks, Wayne!) which is all remotely located atop his 70 telescoping tower; the "station" sits at about 75 feet and the antennas run up to about 82 feet above ground or so.  From the coastal plains of Orange County, CA, this actually isn't bad!  However the site is blocked to the east with very local hills and to the north by the San Gabriel Mountains 30 miles away and over 6000 feet higher.

I (we) had a huge issue with what appears to be QRM from TV CH-13 on Mt. Wilson (LOS); it "wasn't there" in June, but it's there now, and peaks S9+30 when beaming north toward the "tower farm" on the mountain ridge -- making it impossible to hear anything in that direction unless signals were very strong.  To help combat this, I would find myself turning the beam away from the QRM to "receive" stations, then turning it back straight towards the mountain to transmit, otherwise with low power I often couldn't be heard.  Nuisance, but it worked a little bit.

Propagation wasn't much enhanced over the weekend, although I did have a path up the coast towards San Francisco that sets up around dusk and also around dawn.  Working the SCCC "Rover Pack" discussed by N6NB in his Soapbox post was great fun, especially catching knife-edge refraction over the San Gabriel Mounains, with "them" completely on the other side of the range from me (and a ridge 6000-10000 feet high separating us).  We still made it on 10.3 GHz!

Looking forward to another adventure, hopefully with better condx and without the CH-13 QRM!
