Hi everyone,
Does anyone have the setup details for PCSAT32, integrating with USB
ERC-M with G 5500 rotator?
I'm after a step by step setup instructions for it please.

I am hearing reports of RFI from these LED bulbs. Not just HF, but also
VHF.
If you can make any quantitative assessments of such RFI, please let me
know.
And the amazing thing is that at VHF you will never notice it because RFI
is noise power and it is noise power that keeps a squelch CLOSED.
Manuallly open the squelch and sometimes RFI will show full scale on the S
meter yet not open the squelch. And on my radios, when the squelch is
closed, the S meter is inactive and shows 0.

About ARISS:
Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEAM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

Ok, that makes sense. So the repeated signal I heard was simply repeated
attempts at getting the command through and were being interfered with by
the existing FM transmissions. All of the frames I collected would have
actually been DUV and not the same as the sounds I heard. Did camera mode
ever get activated during that third pass?

Hi Rob,
When in camera mode the VT camera follows the following basic sequence: Snap a picture, check how much 'earth' is in the frame, if it meets the 'earth detection' threshold, compress it with JPEG algorithms, break up the result into smaller data frames (8 pixel lines) and send the frame to the flight computer. If the 'earth detection' threshold is not met, the image is discarded and another one is taken, check if there is earth, rinse repeat. There is no long term storage of any given image and the earth detection step is part of the NOAA license. If an image is received by a station, it's a shot from roughly 'overhead', and the AMSAT page has a nifty feature that shows the subsatellite point based off timestamp information from each image downloaded.
I believe there is a 45 minute timer (roughly half of one orbit, the command folks can double check my number there) for the general 'camera mode' of the spacecraft (which is both 'high speed mode' and 'camera on'), with the command stations that start that process in NA. After the timeout the spacecraft goes back into transponder mode (or safe mode, again command stations can correct me there). So it might be tricky to pick up in New Zealand. I know early on in the life of AO-92 there were some experiments to trigger camera mode right as the spacecraft set over the horizon (I believe on ascending passes) by command stations at higher latitudes so that the camera would be active and received by Japanese hams. A similar experiment might work for descending passes and southerly command stations, but it would be smart to look at the footprint/ground track to see which pass might put New Zealand in the footprint within the timer window.

Sorry, the images are real time and the camera is on a 45 minute timer to
satisfy one of our original NOAA imaging license requirements. We did get
some partial pics from Chile yesterday, but VK/ZL is likely too far for it
to remain on long enough to hear.

Back in the usenet days, there were reader clients that could parse entries to make them more human readable. Don?t really care if it?s Linux or MacOS based.

Loren,
It is true that the DUV telemetry would continue uninterrupted, as long
as AO-92 was still in Transponder Mode.? As Drew confirmed the sat never
made it to Data Mode (the mode that enables the camera and high speed
data downlink) and if it had, the same DUV telemetry frames also come
down in the high speed data so you would continue to see them on FoxTelem.

As someone new to satellite operations, I?m finding out that it?s
extremely helpful to not only check the AMSAT status page before an
upcoming pass, but also check reports from AMSAT and others on twitter.
That helps to cut down on the confusion around schedule or mode changes.
For example, helps to know that AO-92 was put into L mode an hour before
the next pass you?re planning to work. Just thoughts to myself this
first week or so on the air.

The last I heard was that it was being launched and then no further

The new amateur payload DOSAAF 85 appears to work very well.
Doppler measurements confirm that it is indeed object 44909,
2019-096E. The satellite identifies itself as "RS44" (i.e. Radio
Sputnik 44) on its CW beacon on 435.6043 kHz. The passband is
about 63 kHz wide. It may also have a downlink between 2400 and
2485 MHz. The frequencies of RS44/DOSAAF 85 have not been IARU
coordinated. The satellite is in an elliptical orbit with a perigee of
1175 km, an apogee of 1511 km and an inclination of 82.5 degrees.
The payload is apparently attached to the Breeze-KM upper stage of
a Rokot launch vehicle that launched three Gonets satellites on
December 26, 2019. It was originally expected to launch in 2015.
It is based on the Yubileiniy platform.

Yeah asked for further details on DSTAR One group of satellites but
the operator doesn't reply to emails and no updates so guessing failed
mission.

There was ONE report of a successful D-Star qso not long after
commissioning.
Then the story faded into history......
