Re: [amsat-bb] Fox -1B / AO-91 in trouble?
Hans,
Looks like if it IDs, the signal is normal and you get the usual 2 telemetry frames. If the transponder has been brought up, you get the odd signal, with a brief switch to DUV at the end, but no telemetry. The command staff have been notified.

My first pass is just after noon. If it hasn't self-corrected by then, I'll try a reset.

Looks much better all right. If cycling the IHU fixed it, that does imply it was an IHU problem, although we could have guessed that the tx was ok, since we were getting telemetry ok. Since the IHU cycled ok, that implies that it was not the program memory. Given that we got telemetry in idle and for a few seconds after the transponder went off, that means a lot of stuff was ok. I'm guessing that probably some bits got flipped in the data for the software high pass filter, which would explain why there was trash in what should have been the telemetry audio frequency band (below 200Hz).

Nothing heard from AO-91 on pass over EM79 a few minutes ago. Sometimes it's me, so if somebody else was able to transmit through the bird, go with that.

First time I remember with THESE symptoms. I suspect most times that memory gets corrupted by a stray electron or proton, it's just as likely to cause a reset as anything, but this time whatever happened was pretty easy to isolate. But the answer is (luckily) usually the same: Power Cycle. 73,

Drew,
The 1921 UTC pass over the continental USA, a pass that went virtually over my head here in central Arizona, sounded like a normal AO-91 pass. I turned the satellite when the satellite was up a couple of degrees from the horizon after my AOS time, and it was transmitting for the rest of the pass here in Arizona. I was using my TH-D72 HT & Elk. I didn't have my SDR receiver going, but it looks like stations across the continental USA picked up telemetry. I posted my MP3 recording from the pass in my Dropbox space http://dropbox.wd9ewk.net/ - look in the "Satellite_Audio-2019" folder, and then find the file "20190430-1921UTC-AO91-DM43bl.mp3".
Next pass here is very shallow around 2100 UTC. If I have a break, I'll give it a try.
73!

Drew,
At 2059 UTC Tuesday, I had a 5-degree pass here in central Arizona. After almost a minute past AOS, I was able to turn the satellite on. I talked through it for about 4 to 5 minutes. I didn't hear anyone else, but the satelilte sounded good for a low pass. I also saw telemetry being collected, and saw the last packet was received at 2110 UTC - a few minutes after I was out of the footprint. At least there will be more telemetry from that pass up the US west coast, by keeping the downlink on.
Not that the audio may be needed for anything, I uploaded two MP3s from this pass to the "Satellite_Audio-2019" folder in my http://dropbox.wd9ewk.net/ space - one starting at 2059 UTC, and the other starting at 2101 UTC.
73!

Drew,
Today's 1941 UTC AO-91 pass over much of the continental USA sounded fine. Some stations early in the pass, then many more as North Dakota and N7AGF came into the footprint. Along with the activity on the FM repeater, the telemetry page shows several stations uploaded telemetry during the pass. My audio from this pass is in my Dropbox space http://dropbox.wd9ewk.net/ (folder "Satellite_Audio-2019", then look for the filename starting with 20190501). I was using the same TH-D72/Elk combination today that I used yesterday.
It appears the reset you did to AO-91 yesterday fixed the issues. The two passes yesterday, along with the pass earlier today, have sounded normal.
73!

It was one of the busiest passes I have encountered and it isn't even Saturday yet !! Heard many new calls and tried calling back but got stepped on, probably from guys operating simplex, finally got N7AGF when the bird was almost LOS. No worries, it was a fun learning experience. 73!
