[amsat-bb] Re: AO-51 Status

[Zachary Beougher]

I was on the 1153z AO51 pass this morning, and it shut off on me at about 
1157z, came back on briefly, went back off, and then it went behind the 
trees before I ever heard it come back on.  I didn't note any projected 
eclipses on that particular pass.  I figured the on/off was just the power 
fluctuations (is that what it is called????), but I was wondering if anyone 
else in the Midwest/West was listening to that pass?  I was trying out a D7 
I got from a friend yesterday, and I couldn't tell if after AO51 shut off, 
came back on, then went back off if the reason I could not hear anything 
else was do to my poor receiving behind the trees, or did AO51 stay off for 
that long period of time (it would have been off all the way to LOS here, 
which was at 1205z)?  Could someone else that was listening to the 1153z 
AO51 pass tell me if after AO51 went off, on, off at approx. 1157z if it 
came back on afterward?  A recording would always be appreciated if 
possible.

73!

Correct. The shutdowns should only be happening during morning passes (when 
the eclipses), or if we have the data transmitter on for too long like this 
afternoon. However, when the repeater is on, it should be very strong, at 
about 1.5 watts on the downlink.

Users can leave the 67Hz tone on and forget about it. If not needed, it 
won't hurt to be there. No need to think about it after enabling it on your 
uplink.
