[Ground-station] GNU Radio Help Needed: OreSat Team (time sensitive!)

[Michelle Thompson]

Greetings all,

Please read the message below from our friends at OreSat and speak up if
you can work with them to diagnose the problem preventing a clean handoff
on 11 January.

OreSat's public repository is here: https://github.com/oresat

OreSat's 0.5 website is here: https://www.oresat.org/satellites/oresat0-5

There are quite a few repositories in GitHub. Glenn, would you please point
out where the problematic flowgraphs are?

-Michelle

Hey Michelle,

If you, or you have anyone who you know who is knowledgeable with GNU Radio
and is willing to help us with an odd buffering problem, we would be
totally appreciative.

Our team here at OreSat is having a bit of an existential crisis regarding
GNU Radio. We are using a HackRF One for transmit and a RTL-SDR for
receive, to send our fairly simple GFSK traffic through our ground station,
and we are having packet buffering problems. The flow graph communicating
through UDP sockets is behaving strangely when sending the packets. At
first things were fine when our packets were small, but now varying the
packet size, ever so slightly, is causing things to go wrong.

We are totally willing to share our flowgraphs and testing procedure, as
you know we are totally open source, so they currently are online at our
GitHub site. We will tell you everything we are doing!

Anything you could help with would be great, particularly since we are
doing integration testing right now of our OreSat 0.5 cubesat, for a
handoff on 11-Jan-2024, and this has just cropped up.

Please let me or Andrew know what's possible.

Kind regards and 73,

Glenn, KJ7SU
