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.

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.

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.

Documentation Day!
Some great news about #ribbit, #rfbitbanger, #Haifuraiya, #Neptune #DSG, and more coming out from all the folks at @OpenResearchIns
Thank you to everyone doing ambitious work!
Wednesday's #dumbbell antenna presentation to #RATPAC went very well and kicked off another set of modeling, to be delivered this coming Tuesday.

There has been a lot of #OFDM work for #neptune, and #polyphase work for #Haifuraiya over the past week. We're looking forward to another great week ahead.
Haifuraiya, by the way, is an #opensource #heo or #geo communications payload for #hamradio.
There is a lot of great work going on, but if you have not been hearing about it and want to, then please add yourself to our newsletter audience here: https://www.openresearch.institute/newsletter-subscription/

Documentation Day at @OpenResearchIns today and the updates are rolling in! We'll have a really nice April Inner Circle newsletter.
Thank you to #haifuraiya #ribbit #rfbitbanger #regulatory #RemoteLabs and all our other #opensource #hamradio teams working hard to publish great work.
It's an honor to help make it happen a bit easier and faster.
We welcome people wherever they are. Learn how to get started here:

It was another fantastic week in #opensource #digital #radio. I call this type of work OSDR.
There's #ribbit and #rattlegram, #Haifuraiya, #rfbitbanger, and two more projects without snazzy names that are coming together rapidly.
That's just a part of what is going on at @OpenResearchIns
And there is so much more out there. Tools development, #AI, free tutorials on nearly any subject, and (supply chain permitting) cheap computing and components.
It's a great time to do this sort of work.

Notes for a talk on #Haifuraiya covering the #polyphase techniques used in the #microwave #receiver design.

Final stretch of an important component for a COBS protocol decoder. This goes into #Haifuraiya which is an #opensource #HEO or #GEO #amateur #satellite on the #microwave bands.
This writeup shows how the #VHDL was designed for the #FPGA used.
There's a bug with tlast right now, but it's a problem only when frame delimiters are stretched more than a byte. This isn't something that "should" happen, but it "could", so the decoder is designed to tolerate it.

The current #JAMSAT Journal has Open Research Institute's #opensource #amateur #HEO #satellite proposal, called #Haifuraiya. Plenty of details, runs pages 17-29.
