@adisonverlice IDK about FCC regulations.

All I know in #Germany is that @BNetzA does allow #data transmissions on select CB radio channels in that 27MHz band which is also an #ISM band where they are tertiary users.

• And whilst licensed amateur radio operators are not allowed on it, unless one violates #SpectrumRegulatioms by using a transmitter not certified for compliance and/or illegal transmission amplifiers and/or excessively and disruptively acts on it, noone really cares.

There are bigger #SpectrumViolators with higher priority for them to search & arrest, like unlicensed and illegal users of restricted frequences like fmr. 2m & 4m emergency services radio bands, illegal #UHFSATCOM in the 243 MHz band among other things.

• Same goes for any #SpectrumAllocation incl. #LoRa / #LoRaWAN: Worst-case one could use that or other options...

@sundogplanets Yes, and that's a reason why #Megaconstellations like it (and others as well as predecessors like #ICO) are garbage.

Compare that to say #Iridium which launched with 77 satellites and those lasted 25 years, way longer than scheduled, and got recently replaced with a new generation instead...

• Granted even Iridium required bailouts and basically catering to the #US military & intelligence market with their #PTT offerings that unlike #UHFSATCOM at least have #encryption on.

Not to mention #Starlink is a #SpectrumPollutant and can only serve as means to #sabotage #Fiber deployment #ROI espechally in rural areas, thus increasing #DigitalDivide further by making #FTTB & #FTTH buildups (even with government subsidies) harder to justify.

@kallemp I didn't bother with #LoRa due to it being patented and #Meshtastic for tending to pollute #ISM spectrum.

Also #CEPT does have data channels on #CB radio that are allowed to be used.

• Given the low duty cycle, I'd say it's worth using said #LicensingFree channels. Espechally since the only "regulated" part are transmitters and those are just transparent cheap boxes, so #AFSK will be fine.

OFC one could use this across any spectrum or means, ranging from WSJT - moonbouncing at extreme narrowband and high frequences to #UHFSATCOM radio piracy. Obviously I disrecommend the latter for legal reasons!

• OFC one could also use it across i.e. #Iridium and other #SATCOM and regular #VHF & #UHF radios or even just print messages as QR-Codes...

@HonkHase Hoffentlich wird die #Bundeswehr für ein #BwSATCOM-3 dann sowas wie #Iridium bzw. #IridiumNext fahren wollen, weil das geht mit überschaubarer Satellitenzahl sehr gut!

• Weil sowas wie #NettedIridium aka. #IridiumPTT for Military sollte easy machbar sein.

Ich rechne allerdings eher damit dass diese ne #TDRS-mäßige Konstellation für #UHFSATCOM & #Xband-#MILSATCOM aufsetzen werden...

• Bleibt zu hoffen dass es ein offen spezifizierter & sicherer Standard ist und kein proprietärer Bullshit alla #TETRA oder #SCIP...

@mastodonmigration @GottaLaff noone relies solely on #Starlink, espechally given it's big-ass dishes.

• Even the #US #DoD uses #Iridium & #UHFSATCOM.

• #SES & #Eutelsat have various commercial #Cband, #KuBand & #KaBand transponders for bidirectional data from their GSOs.

• #XTAR has a #Xband-Spotbeam.

• #Ukraine has both #Fiber and #Radio links (civilian and military) to link together units and emplacements. Espechally direct-burial/lie-flat fiber is used because #COTS parts are cheap, commonplace and unlike copper, they can do 160km+ without amplifiers with ample of room for splices.

Pretty shure Starlink was a mere "comfort feature" allowing units to send their drone footage from their FOB to HQ for instant #Meme|fication and "scoreboard updates" but I'm shure worst-case the #NAFO friends will just pack in some 2,5" SSDs and USB cases with the next supply trucks or have some #Skyhook-Style delivery system if that was ever needed.

• I'm shure the folks in the trenches will miss YouTubing in their toilet break, but I'm shure they still have enough #Memes and #Entertainment in reserve to compensate for it.

@cafkafk All I know is that #UHFSATCOM has been plagued with #PirateRadio transmissions abusing the 243 MHz area band #satellites as global repeater.

• Ranging from #Truckers in #Brazil to #Cartels to #RadioStations to people abusing it as a #Telephony relay in lieu of #SPSC on C-Band...

That's like 20+ year old #OSINT by now: Basically everyone with a #SDR like a #HackRF can send on those and for recieval some simple #UHF antenna and a DIY dish made out of chicken fence aimed at the GSO-bound satellites is all it takes...

• OFC the #DoD will not like illegal transmissions but as per very nature it's trivial to recieve said messages for everyone who isn't lazy...

@ai6yr @michael_w_busch yeah, #UHFSATCOM is plagued with abusers in the 243MHz band...

@kenji that's only the 1st one publickly acknowledged...

There have been others in the past, but you can imagine how "understanding" the U.S. Miliary is about abusing their #UHFSATCOM infrastructure...
