NFL. Ukraine military is really smart. It will be a blow to lose Starlink, but they have certainly established contingency plans for this eventuality.

@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.

@kkarhan @GottaLaff

NFL. Seems like they would be foolish to imagine Starlink to be secure as well. Certainly nothing critical could be trusted on the network.

@kkarhan @mastodonmigration @GottaLaff

Trust no network, not even your own.

@admin @kkarhan Trusting the network run by a guy who has arm spasms reminiscent of the Third Reich would be... unwise. Full encryption on it, and realize your dish location will be transmitted to whoever wants it.

@ai6yr @admin OFC it's trivial to find a transmitter when it transmits.

• Which is why Ukrainians hide their dishes well [infosec.space] inside buildings and away from the actual troops...

Also critical comms still uses #analog #PTT #Radios where only the transmitter can be detected during transmission, so troops can be commanded & warned without putting them at risk.

• OFC they gonna transparently encode & encrypt stuff but the ISM Bands & CB-Band is lit af...

@kkarhan @ai6yr
From what I've seen and been told, the go to radio for the UA is a Motorola HT or mobile using AES256 encrypted DMR. You can get an off-brand chinesium version DMR HT for under $100USD. (TYT MD390UV)

@admin @ai6yr Again, that's one of the tactical radios in use.

I know old German PTTs like the FuG 7b got handed over - freshly decomissioned after EMS & Fire Departments went fully digital (TETRA) in Germany.

@kkarhan @ai6yr

By PTT, do you mean a handheld radio? They are called HTs, for Handie-Talkies™ from the Motorola classic marketing name for them. PTT means Push-To-Talk, which is non-specific.
In some circles the term is more correctly RTL, or Release-To-Listen.

@admin @ai6yr yeah, abeit the old FuG 7b isn't really handy: It's about the size of a Cigar Box and weights about a kilo with a huge-ass NiCd - Battery screwed on the bottom.

• Granted, it's 1970s tech...

@kkarhan @ai6yr

Specifically the Motorola XPR series, or whatever they call the EMEA version. These are not even Public Service rated like the APX series, but still well built and easy to service. They are considered commercial grade.

@admin @ai6yr I know these.

They were in use in German Fire Departments until they migrated over to TETRA...

@kkarhan @ai6yr
While the invaders use cheap $10 radios from Alibaba.

@admin @kkarhan BF-888S, LOL.

@ai6yr @kkarhan

Makes them easy to monitor since they transmit on every harmonic.

@admin @ai6yr yeah, these things are so bad, pretty shure @BNetzA has rejected #certification due to lack of #SpectrumCompliance and proper bandfiltering!

@kkarhan @ai6yr

Last night I ordered up two MD-UV390s with OpenGD77 to run as hotspots. https://letsgetreadyinc.com/opengd390plus
