Big step forward for the #AMSAT_UK Mode Dynamic Transponder (MDT) Successive Interference Cancellation (SIC) design from @OpenResearchIns

https://github.com/OpenResearchInstitute/Mode-Dynamic-Transponder

Polyphase channelizer for digging out weak signals on 70cm from space. We'll use the same design to make a communications channelizer for #Haifuraiya.

Our 6 February 2024 #fpga meetup for #haifuraiya, our #opensource #hamradio #digital #satellite project, is now live.

We talk about the integration of the #polyphase channelizer on the receiver and other updates. Thank you to those that support our work at ORI.

Thank you to all the volunteers making things possible at ORI! It’s been an action-packed week and it’s only halfway done.

#RFBitBanger batch 2 kits are more than halfway packed!

#Neptune systems and implementation work? ✅

#Haifuraiya GEO/HEO comms RX polyphase filter? ✅

Found a potential issue with the Theseus Cores #polyphase channelizer. The volunteer already has a fix in mind, and it's not a deal-breaker for lab demonstrations.

#Haifuraiya progress! This is an #opensource #satellite #communications design and will be prototyped on the #hamradio #microwave bands.

Big #fpga things happening on #Haifuraiya at @OpenResearchIns

Stitching in #multirate processing and getting an on air demo for #opensource #amateur #satellite service designs is going well.

Thank you to #amsat-ca and #amsat-dl.

The magic of seeing the people I support at @OpenResearchIns get great things done never gets old!

Thank you to all our volunteers for another great week. Getting up on a Monday and being able to dive right in and help #opensource digital radio work is a privilege that I do not take for granted.

Most of what we do is on the #hamradio bands and is of direct benefit. The proof is what's on the air, from #ribbit, #RFBitBanger, #neptune, to #Haifuraiya

Next demo? #defcon32 at #RFVillage.

Video recording of this week’s meetup about #Haifuraiya progress below. This #opensource microwave broadband transponder has space & terrestrial applications.

Prototype works on the #hamradio microwave bands. Thank you to Analog Devices and AMD for the support this week.

Testbench passing for #polyphase channelizer for #Haifuraiya, an #opensource #HEO or #GEO communications #satellite design. Applicable to #hamradio, 5 GHz uplink and 10 GHz downlink. Shown is the transponder receiver filter.

If you’d like to join this or any other @OpenResearchIns project, get in touch.

Thank you to everyone helping with both #ribbit and #rfbitbanger, and with all the #fpga work for #neptune and #Haifuraiya

We couldn't do it without you. Some great #opensource #hamradio work going on supported by @OpenResearchIns and #ARRL, #qsotoday, #RAPAC, and more.
