KBOS1965 said:In the interest of completeness, I'm pretty sure there was one additional site applied for for critical hours operation. There were at least a couple of issues that cropped up early on with the original applications. I think one of them involved adjacent or second adjacent interference with the station in Soledad. One thing that I think came out of that was that the Soledad station's antenna pattern was not oriented as originally licensed, but was not corrected because it was not otherwise causing a problem. My memory may be faulty, so correct me if I'm wrong.
I don't remember a different operating mode for CH, but I do recall that the height of the tall towers at the proposed (but never built) day site were reduced slightly to avoid CH interference to co-channel CJBC Toronto.
As for overlap with a station south of SF Bay, it was second-adjacent KKMC 880 Gonzales (10 kW DA-2). It was discovered that the towers of that station were built along an azimuth different from that specified in its CP. A new CP was issued and the patterns were tweaked so that the actual facilities and the license would agree. KKMC is now licensed with minimally changed parameters.
