Thinking of dipping my toes into #LORA. For somebody in inner-west Melbourne, do I even care about #meshtastic vs #meshcore ? Do I just buy a #Seeed T1000 and flash one or the other firmware to see how the networks compare? Can I plug my #SDR kit into my #pi and communicate with it over one or both protocols?

Hey #plane bubble, is there any existing solution to store #ADSB using #tar1090 toolchain for longtime playback of all the surrounding plane movements? And to query it to get all flights within certain height, time patterns, ...? Preferably something to feed trajectories into #QGIS or #movingpandas ?

And lastly, until the remaining two articles work their way through the publication queue at least, is the HTWAVE Integrive-100, an upcoming hardware-accelerated standalone software-defined radio built around an AMD/Xilinx Zynq-7020 #FPGA and an Analog Devices AD9361.

£30 #sdr and antenna is much preferred to ~£300 dedicated device.

I know I'm seeing a breach of etiquette, but the chiding I see from time to time in FT8 kind of makes me grin.

@tschaefer i do ipv4 only for lack of complexity sake but i understand we are running out of addresses. maybe i just don't understand or appreciate the real appeal of ipv6 #arin #name rez #sdr #hosts #bind #unbound

Full confession: I run IPv4-only at home purely for simplicity. I get the address scarcity issue, but maybe I just don't see the real appeal yet.

The Core Appeal of IPv6: It's not just more addresses—it's about reclaiming end-to-end connectivity. No NAT, no port forwarding hassles. Every device gets a globally reachable IP.

For DNS/Naming (like #BIND/#Unbound): It eliminates the need for ugly NAT reflection/"hairpinning" to access internal services from your LAN. The host just works, internally and externally.

For SDR/Hosting: Imagine running an SDR server or a personal host—you can give it a static /64 prefix and actually reach it without wrestling with UPnP or carrier-grade NAT.

The Complexity Trade-off: You're right, dual-stack is complex. But the long-term play is IPv6-only with DNS64/NAT64 to handle legacy IPv4 traffic. That's actually less complexity than maintaining two parallel stacks forever.

#ARIN Reality: They're essentially out of IPv4. If you need more than a tiny allocation, v6 is the only path forward."

Bei einer führung meinte der guide gerade, dass ahrweiler und umgebung das problem allerdings demnächst von alleine.nndie spannende frage ist jetzt: ist das nur nicht mit? das ist doch ok. definitiv kein hassmartin. #sdr

@stefani A couple of my #HamRadio friends seem to like the Pluto and clones, so I guess I'll go that route. #AmateurRadio #SDR 👍

Ever tuned into your FM radio and suddenly picked up a station from 800 miles away — crystal clear — only for it to vanish minutes later? 👀📻
That's Sporadic E Propagation — one of radio's most mysterious and thrilling phenomena!

@truhe Vorsicht bei HDR, da wird gerne viel gemurkst, oft auch ohne Wissen der Filmschaffenden. SDR ist der Kinofassung meist näher und 2K reicht locker für die physisch begrenzte “Auflösung” unserer Augen.
