AstroPi Projects on the ISS

More than 6500 projects have been run on the two Raspberry Pi computers aboard
the ISS - ALL submitted by  students!

AO-73 - Full-time Transponder Mode

Just Saw SpaceX' Vehicle ...

Well, THAT was exciting. 9:59PM pass of the ISS was visible for 90 seconds - and trailing it was the SpaceX vehicle - visible for only 15 seconds ...

TOO MUCH excitement for one day ...

Re: Question about getting into the Sats

Yes, the tones and freqs are all in memory presets and I have worked all these FM birds before.

Thanks and 73

Did you have the tones set for the satellites?

Hi All,

I am a newbie at this and having a bunch of fun. But today, I had problems getting into a couple of satellites.

The first 2 attempts resulted in no contact at all. Did not hear myself at all (full duplex) but heard other stations fine. These were for AO-91 and AO-92. One was a low pass the other went almost directly overhead.

Then I tried PO-101 a little later. This pass had a max elevation of only 13 degrees but I was able to get 3 contacts and hear myself fine for perhaps half of the pass. (at least when I wasn't getting stepped on!)

I double checked frequencies and shifts, checked my equipment and it all seems ok. I was able to hit local repeaters, even on extra low power on my TH-D72A and the Arrow pointing away, so I think it's getting out.

What other factors can affect this? I have been pretty successful and have 96 grids in just the past month. So something is working right.

Are some days just better than others for handhelds? I feel like I am missing something simple here.

Thanks in advance for the help.

Thanks. I keep forgetting about 92. With the holiday, I was off by a day!

However, there are still days when getting into the birds is rough and I was looking for insights as to what to look for.

I will put a Post-It on my forehead about 92.

Not sure about your issues with AO-91 but AO-92 is currently in L/V mode. If you werent transmitting on 1.2ghz you would not get in.

Re: AO-27 ... It's Baaaaack!

Clint Bradford
 

Mixed results the past week or so ... Seems AO-27 will sometimes be on in 145.850 UPlink . 436.795 DOWNlink 
mode for two minutes or so, then switch to telemetry mode.



SO ... Give it a try! And please enter your results on the LIVE OSCAR STATUS page ...

Re: Question about Footprints and WAS/DXCC

Brad Smith
 

From Chicago land you are not going to reach HI on an FM bird. AO-7, yes, with a very low west pass and your Arrow on a tripod. Very few satellite hams in HI, though, but once in a while a rover goes there. Brad KC9UQR

Question about Footprints and WAS/DXCC

Paul AC9O
 

I am still new and learning a bunch about satellites and what you can and can't do. I have some basic questions and hopefully I don't sound too dumb!

I understand about the footprint and that depends on how high the satellite is. And that some satellites have a more elliptical orbit and can be higher at times in their orbit.

From what I can find, all the FM satellites are somewhere around 300 to 400 miles up and their footprint limits how far you can contact another station when you are both at the edges.

I am in Illinois, and it looks like Alaska may be possible if there's a station in the panhandle. But Hawaii seems like a footprint too far.

Some linear satellites are higher, but that's of no use if all I have is a handheld FM rig.

Have I got it right?

Thanks to all and 73

Other satellites are there, it's just that most of them are too dim to "see". I had to go down about 15-20 sightings before I ran into a few others that you could see.

I am new to satellites, less than a month. And having a blast!

Most definitely full duplex. I started with a TH-D72 and a headset. It worked great but had a tough time recording sessions on my smart phone. It can be done as the smart phone hear me very well, and can actually pick up the downlink audio enough to hear. the problem is with external noises, neighbors, cars, etc. can mask the receive audio. I didn't want to patch in another recorder, so I lived with it.

I then took my other ht, a FT3DR and use that now on the downlink. It has built-in recording so it works great to enter logs after the session.

Here's a pic of my setup with an Arrow mounted to a camera "C" handle with the HTs on either side. Very comfy to hold and control....
