Big ears listening for AO40



I finally found some time to fire up the 12m (40') dish to see if I could
hear AO40 at apogee.  I used Ken's KEPS below, and did a conical
search out 5 degrees in 3 Khz steps from about - 10 KHz to about + 
10 Khz from expected DOppler from 2401.305 and heard nothing at
60,000 km.

There are many unknowns.  My appologies for not being able to keep up with
all the AO-40 msgs, but there has been so many messages of no value, that
I have just had to delete anything with AO-40 in the subject line just to
stay afloat...

I only make this post for confirmation of the 2401.305 is the 0-doppler
value?  and someone to confirm that these keps are within about 5 degrees
when AO40 is near appogee.  I did my search from about 1500z to 1630z,
today 28 Dec using the below keps.  My beamwidth is less than 0.5 deg, so
no sense in my continuing to search if any of the above are too far off.
Is the S-Band beacon now on 100% full time?

If I do find it, with a lot of effort, we could possibly provide a feed
while at Apogee...
