Telemetry hunters: What are your plans for the SSO-A launch next week?
All,
If you are interested in satellite telemetry, what are your plans for the SSO-A launch next week? There are a large number of satellites with telemetry downlinks spread over 2m, 70cm, and 2.4GHz and right after launch they will probably all be clustered not-too-far-apart.
Getting telemetry from more than one of them seems problematic although I suppose you could get an SDR and record all of 145.8-146 or record all of 435-438 MHz with the intention of post processing the recording for each satellite of interest. Is anyone planning on doing something like this, or is everyone just going to go after one or two satellites? If you do make recordings, particularly if they have multiple downlink signals, I'd like to get a copy.

Great question, Douglas.
I particularly enjoy telemetry & digital modes. While this number of transmitting sats is a bit overwhelming, I'll probably take the approach that I've used for past multiple deployments:
-early passes, monitor a wide spectrum to see who is transmitting at all. Just see where the marks line up on the RF spectrum and see what I can match with a published frequency.
-later passes, give attention to sats that are supported by a public-domain decoder & an active project team. So, right away that means Fox-1C, Irvine-02, MinXSS-2, & PWSat-2.
-after that, the "squeaky wheel" sats... if there is an appeal from someone for help from the Amateur Community to listen for a sat that hasn't been heard from, etc., I try to put a priority on those objects.
Beyond that, they'll start to separate and everyone can give attention to the satellites that interest them the most.
Good luck to all involved - this should be interesting.

Hi Scott, Please add JY1SAT to your list! https://funcube.org.uk/2018/11/15/jy1sat/ has all the information about deployment times, new UI software and the new Data Warehouse...it has been a very busy time for the small AMSAT-UK team that has been putting all of this together! We will really appreciate all reports. Also listen for ESEO - we will be publishing details of this mission within the next 24 hours. Exciting times...... 73 Graham G3VZV

Note that one can certainly run multiple copies of FoxTelem connected to the same FunCubeDongle as long as they all use the same center (i.e. local oscillator) frequency. I've been told, but have not tried it, that is also works with FoxTelem and the Dashboard. Apparently only one program can CONTROL the dongle (i.e. center frequency, turning on and off gains etc) but many can get the IQ audio out of it.
Worth an experiment!
