Satellite Comms Engineer by day, SDR and Ham Radio in the off time.
Another new set of receivers at the Goonhilly WebSDR site - this time for the motus.org Wildlife tracking project.
A set of four (N,S,E,W) UHF yagis with RTL-SDRs on a Raspberry Pi will allow them to detect any tagged species migrating across the Lizard peninsula.

We're feeling that sun today from here 271M km away as Goonhilly-6 provides TT&C from the ever-blue skies of Cornwall, UK!

Watching the EI1ISS ARISS contact on live.ariss.org , and listening on M0XGH AMSAT station at Goonhilly - great copy in Cornwall!

Updating the operating system of the server switched off old insecure TLS ciphers - which broke some windows software using the FFT Websocket connection (QuickTune, LiveTune, OpenTuner, etc.)
This has now been resolved by re-enabling the old TLSv1.0/1.1 ciphers. (yay legacy software!)

Sunset in Cornwall. Looking closely you can see that Goonhilly-6 is not quite pointed at the moon. Not yet.

An upcoming scheduled power outage at the Goonhilly WebSDR site means this'll be reset soon..

After a spectacular sunny day in Cornwall, it's a clear cold night to stare moon-wards in another lunar mission validation campaign.

Using the brief moments of sun today to sort out @ARISS_Intl HAMTV dish alignment.
Now just need to work out what to do about that both-adjacent-channel RFI! (ignore Pluto DC spike at centre)

FYI we have resolved the 2m-band RFI issue on the Goonhilly VHF WebSDR. Culprit seems to have been a misbehaving SMPSU that is cooperating after being remotely re-powered.

Feeling plenty of nostalgia from these old IQ recordings of the ISS HamTV downlink recorded during ARISS Principia in 2016.
(I've started testing our latest generation of DATV receivers with the multi-groundstation TS-merger, to be ready for the repaired TX in orbit soon 🤞 !)
