    Why could not 1150 diplex wth KBPS?

    At a quick glance the 1450 tower would be less then a quarter wave at 1150 even if they could use the entire length which would mean a total reconfiguration since it is now shunt fed which sacrifices some of its length (below the feed point) electrically. As Semoochie hinted at, it would be cost prohibitive not to even mention the time frame to come to agreement with PPS/Mult. County, etc. etc.

    So not a practical nor cost effective solution and it would only yield a very poorly performing result without more steel. The 1520 towers are an exact quarter wave at 1520 so they are even less as you go down in frequency to 1150 so although doable, WTFF? It probably couldn’t provide enough coverage anyway. They need to find a bigger tower or build a new site.

    110 mph wind gust @ Mt Hood Meadows.
    Not my idea of a “nice” transmitter site.
    The FMs from there still on the air tonight?

    88.7 ok, 89.5 no modulation, 90.3 ok, with some audio drop out… signal strength on all 3 about normal.
