[amsat-bb] re: AO-27 orbit 31511 no downlink?

[John Mock <kd6pag@xxxxxxx>]

    I've worked though AO-27 from the very same location with the VX-5 and an
    (admittedly different, borrowed) Arrow antenna. 

    The element set epoch on the Keps I'm using is 04 May 1996, and SatTrack
    predicted AOS at 11:35, MEL at 11:42 and LOS at 11:50 for FW29KW...OK, so I
    was someplace in FN20; it shouldn't make *that* much difference.

OK, your KEPS vastly too old, get some that aren't more than a few months
old, which will be fine for this bird. Here's a few days of predictions for
Philadelphia to get you started in UTC:

I'll try to be on for the second Friday pass if you want to work California
but expect it to be a mob scene, as those transcontinental passes often are.

P.S.  I'll go get some fresh KEPS for myself and them to you via a separate 
e-mail.  You probably should get a more current 'modes.dat' file as well.
