@jt_rebelo @mastodonmigration @GottaLaff I'd call #Ukraine "criminally incompetent" if they didn't already leverage domestic #Fiber & #GSM networks as well as procuring entire transponders for exclusive use.
I couldn't confirm X-Band use with either #XTAR or #BwSATCOM-2 simply because I have neither teleport access nor matching LNBs/BUCs ready, but existing press releases by @Bundesregierung & @AuswaertigesAmt hint that Ukraine has been upgraded to #NATO #Link22 capabilities.
Existing #SIGINT & purchases show huge amounts of COTS #KuBand & #KaBand and even #Cband-Equipment being used since 2022, which use higher-ping #GSO|s but are easier to decoy and protect against #ElectronicWarfare and #Sabotage (just by shoving the dish into a partially buried sewage pipe, making it look like a ghettohacked Copy of #BARS, the Soviet-Era #Troposcatter CnC Radio...

@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.
#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.

This C-band LNB is a bit crusty. But might even work!
Should be usable for seeing 3.4GHz stuff on the spectrum analyzer, even if the DRO in this thing is not super stable.
Has anyone converted these to 5.7GHz?
The LO is 5150MHz
Shouldn't that just be ripping out or replacing some filters?
I wonder if it would upconvert with sane effort.
Gain is much cheaper and less fiddly on 3.4GHz and 5.7GHz than 10.3GHz.

#5G update: #TMobile has dropped 2.5 GHz (Band 41) #LTE entirely in a number of markets, including Austin, widening n41 by the same amount. I think the #Austin switchover happened at ~9:20am this morning as a friend briefly lost connectivity right around then (probably cell site reboot), prompting me to look at my phone's field test.
I found a sweet, sweet 100 + 80 MHz of #n41 live, which is well above what #Verizon or #att can bring online with #CBand right now.
750 Mbps indoors at home FTW!
Being out of town from D.C. let me finally try out Verizon's #CBand 5G, and the results from near downtown Dallas on an Inseego hotspot were pretty good: 221 Mbps/34.7 Mbps. That's not as fast as T-Mobile 5G, but Vz's previous options were low-band "nationwide" 5G that wasn't much faster than 4G or exceedingly fast but exceedingly unavailable millimeter-wave 5G.
@thebaldgeek I am betting you got a PLL #cband #LNB and it is sensitive to the cold. This has been a problem with these LNB's for a long time, as you can see from this article from 2016:
Are phase-locked loop (PLL) LNB’s a good idea?
https://freetoairamerica.wordpress.com/2016/06/06/are-phase-locked-loop-pll-lnbs-a-good-idea/
(Note the last EDIT down near the bottom of the article).
I don't know how cold it gets where you are but I suspect you are going to have issues during any cold weather event. In theory you could attach some kind of heating element, like a small reptile tank heater (make sure it's waterproof) and turn it on a few minutes before you want to watch TV but IMHO those things are just poorly designed, even if they are being marketed as a solution for 5G interference.
Pulling my hair out of late (wait, Im bald!).
I swapped the #LNB on the #cband dish because I was getting, what I suspect is #5G interference for an #LNB that has a filter.
Turns out the new LNB is a bit of delicate snowflake and is unhappy outside of a very small temperature range.
I have already done the #GPSDO modification, so its not that.
Long story short, I thought it was a tracking issue for a good while, but now working on getting a stable temperature range for it.
Quick update. Usual insane #ACARS day here. Working with a guy in Ireland on #VHF VDL2 #RTLSDR v3 message logging. Then helped a guy in Ireland about L-Band system handshakes.
Got to do a bunch building the #L-Band #Helix #antenna, but did not finish as a guy I have been helping in Maine get running on data from #Inmarsat #CBand needed some help.
Bottom line, close to a world-first here. #ADSC data from 54w.
We now truly have global coverage from all 4 satellites!
High-end early 80s technology being delivered to our house by my Dad, bought from a friend who was an early satellite equipment dealer. Unscrambled satellite, those were the days and the house overhead with the "dish" in the backyard for scale. #Satellite #CBand
