How many here are ham radio or other radio operators?  I would love to hear some people during my travels.

Just worked a FoxSat, AO-91. It flew right over us. 

It's an FM repeater on a new ham satellite recently put in orbit.

Those hams in remote areas (no urban jungle in the way) with a 50w mobile and a decent mobile antenna can work this one!

145.960 downlink. (set your receiver to this freq) 

435.250 uplink, with a 67hz tone.

Here is the tracking page:

And here is the detailed RF info to correct for doppler shift on transmit:

   

It's moving at around 4.6 miles per second, but its about 400-600 miles up so it has about a 1000 mile footprint as it passes over you.

Good luck!

Since I've not worked a satellite before, what constitutes a decent mobile antenna?  A 5/8 whip would do it or no?

Yep! Some hams have worked this one with a 5w handheld and portable yagi.

Of course a yagi or quad does work better, but most of us don't carry a dual band portable or azi-ele CP yagi with us on the road, other than for special events. 

But yes, if you can hear it, when it passes over within say 300 miles of you, then you can work it. Comms are very quick and very short! Over the last 2 weeks, I have even heard it twice via tropo when it was out over the Atlantic...

If it passes directly over you, with that type of antenna, it will probably fade out, but give it a half minute or so, and it will be back in your antenna's gain pattern. 

If you have a dual band, dual receive mobile, program one memory on VHF for the receive, and just keep listening or scanning. 

Program the uplinks on the UHF side in at least one or two memories and then you will be ready to go.

IF you hear it, use high power, and throw your callsign out a few times. If you can operate full duplex, you will hear your voice thru the repeater. 

If you hear your voice, others will also.

Good luck!

Neat! Back in the day I contacted the Mir space station with my regular base station, 45 watts and an omnidirectional vertical antenna. I can hear the ISS on a handheld radio easily. Now I may have to go try AO-91 from the car!

Cool!

I have made exactly seven space contacts with astronauts. A few of those contacts, I was able to record, and at least one that I know of was recorded by someone in Nebraska, and the audio file was on their website for awhile.

Seven might sound like quite a few but that's only 7 contacts in 31 years of being a ham. 

So it's not that many. 

But I have made numerous ground to ground contacts thru ARISS and other orbiting systems over the years....too many to count. 

For me it's an interesting 'extra', since I have not spent any time or money to set up a station dedicated to satellite work.
