[amsat-bb] AO-92 L Band

Just had a very low pass here in CM98 - 2 degrees off to the north-west,
over the ocean.  I heard Veronica on the downlink, but was not able to
get into the bird myself. 

I only have 10 watts from my FT-736R into a 32 element
horizontally-polarized beam, fed with 60' of mostly hardline, and some
RG-213 at the ends.  So, I'm guessing no more than a couple of watts at
the antenna...  But I was basing Doppler on 1267.350; will try .360
tonight on the 20:47 PDT pass.  47 degrees; should be a LOT easier, too.
