Hi all:
Now orbit #457 + 12 minutes
Double checked. No telemetry at all neither in this pass. EA1JM confirms
the same.Satellite was busy and several stations were making QSOs.
At least from my side, same comments and feelings as in my previous RXed
pass: Nothing have changed regarding the uplink issues and downlink
quality looks to be better (Both audio and signal strength) than when in
the normal modes.
Question: I understood that the uplink dificulties were related to some
issues regarding 67Hz reception on the sat. If the COR mode doesnt
handle 67Hz at all and is an "Open Squelch" mode... Should not "life be
easier" to be repeated by the sat?.

Hi David,
When 67Hz detection is active, the satellite keeps the squelch open for
a minute after it loses the 67Hz tone. In my experience, usually the
satellite will keep its squelch open throughout all the pass or most of
the pass. The satellite will keep the squelch open even if 67Hz tone
detection keeps dropping all the time, as long as it detects the tone
for a couple of seconds often enough.
It seems that the problem is not that the sat doesn't open the squelch.
The squelch is opened but the satellite transmits only noise or a signal
which is too difficult to copy, because the satellite didn't hear the
uplink signal so well, but it's repeating it anyway.
That goes as far as I understand. Perhaps people in the Fox team will be
able to confirm or comment on this.
73,
Dani M0HXM/EA4GPZ.

Just to clear up any confusion about why I uploaded telemetry at 0625utc.
AO-85 and AO-73 are currently passing over VK at similar times.
My prime focus is the capture of AO-73 telemetry.
I had a reasonable capture of AO-85 off the back of my beam on my IQ file.
So I replayed two passes around 0625utc, for a total of 35 frames of
telemetry.

That's a bit weird, isn't it? VK5HI reported telemetry at 6:25 UTC today:
http://amsat.org/tlm/ao85/201511082225427.txt
I coincide in the opinion that the audio is clearer without DUV telemetry.

Oh, I assumed that the timestamps on the telemetry where the timestamps
when the packet was actually transmitted by the satellite, not when it
was eventually decoded and uploaded.
Is there any way of knowing when the satellite transmitted the packet?
It seems that one could perhaps use the satellite uptime and number of
resets.
Then it seems that the last telemetry uploaded realtime was at Sun, 08
Nov 2015 23:30:36 UTC by VK5KJP (uptime=22007).
http://amsat.org/tlm/ao85/201511082121989.txt
Your telemetry has uptime=22211, so it was transmitted by the satellite
some minutes later.
The passes
*Monday November 9, 00:05 through 00:25 UTC*
*Monday November 9, 01:45 through 02:10 UTC*
over NA were when presumably the IHU was to be turned on again, so I'm
not so sure what happened.

My guess is that 28.1215 should put you close to the center of the
passband. And remember, you can just keep the key down throughout the
pass... it is full duplex and so you can see if you are colliding with
someone in the display.
Though listen first on 10 meters, since we are using the same common
frequency band as terrestrial users.

I tried about every 100hz from 118 to 121 and never broke the squelch.

Good point Bob. I haven't fully worked through the problem yet, but thats
pretty much right in line with what I'm thinking. Thats what I meant by
saying watching the 'rate of change of doppler.' When the slope of the
doppler s-curve is at a maximum, that should be the point of closest
approach.
Actually, that brings up a question. Do you know what type of equation
would fit the doppler S-Curve profile? something that could be used to
generate a regression equation from a few doppler observations?

You dont need to know the senders exact freq, just a plot of his freq
during the pass will form an "S" curve and once you have enough of the "S",
you can know his center freq, and hence his closest point of approach.
That gives a line of bearing. Anothe pass gives another one, and so on...

But good point, probably not the best thing for a public demo if your
audience is a bit younger.
Actually, I've seen so much FM activity (basically every time I've
monitored FO-29 since we first came online in late september) that I've
been toying with the idea of trying to locate where the source emitters
actually are located based on doppler shift data. We know the doppler
between the receiving ground station and FO-29, so we can back that out.
We know the transponder mapping, so we can work through that to determine
what the center frequency is as the signal enters the transponder uplink
receiver. What we don't know is the uplink doppler, because we don't know
where the emitter is and we don't know what exact center frequency they are
on (but I bet you its in 5kHz steps, maybe 2.5kHz). So we have two
unknowns. I'm betting there's a way to work through it though, and with
enough observations and by watching the rate of change of the doppler, I
bet there's a way to make an educated guess on what their center freq and
location are.
Or if someone listening knows Spanish and/or Portugese, maybe we could get
lucky and hear what cross streets the taxi is going to (if it is in fact a
taxi).

Lots of strong FM activity as the pass started and the satellite was

towards the north pole, the FM activity died down.

It's not uncommon to hear Brazilian pirates on FLTSAT and UFO military
