Demodulating MTG-I1 raw data @ 26Ghz received in Panska Ves. It is 188M OQPSK 1/2 and RS I=5.
Unfortunately, it is encrapted. It's very disappointing considering it's supposed to be public life-saving data...
S-Band is not encrypted.
I'd call it very much a scam, the software support, i mean its okay, but chinese Zynq 70x0 + AD936x based full duplex SDRs are slowly taking over, RF wise and support wise they are just eons ahead of the dumpsterfire that HackRF is.
Don't buy HackRF, unless you really only mean to use it in the lab... It's obsolete and overpriced (could be called a scam even)
No, nic proti solárům, ale vyřešilo by ti to jen tvoji spotřebu, max spotřebu sousedů na stejném spanu od trafa.
Na národní síť by to chtělo víc zdrojů se setrvačností (ano, tou vlastností hmotných těles).
Ale z dat ENTSO-E to vypadá že to ve Španělsku někdo solidně posr....
Pusť si TLoU herní playthrough (bez komentáře), věř tomu že je to násobně lepší než seroš.
Nechci... nechci nechc.... safra už ne🥲
90% of those folks would probably get coiled into a lathe the moment they turn it on
And it's gone... I decided to give my 180cm prime focus dish (and so my X band capability) away.
It served me good, but it's been sitting idle basically since Autumn 2023, it'll find use elsewhere.
Soo.. yeah.
I got a 320cm dish, quite shallow at around ,54f/D but that's fine. It's got a 10x10x1mm mesh so theoretically useable up to around 2.9GHz until the leakage becomes noticeable.
Just need to figure out the stand for it!
Budeš mít prioritu numero uno, už jsem to hodil i na hambazar 😅

Chci do světa poslat tohodle krasavce. Band Decoder MKII od @/ok1hra,
Kdysi jsem jej postavil jako kit, a od té doby leží v šuplíku, nepoužitý, maximálně pár miniaturních oděrků.

Cenu si představuju kolem 2tis. CZK, kit mne tehdá vyšel asi na 2.5...
Yeah they are, i don't know any post-soviet groundstation that would keep them.
Hmm, how about LOFAR, can't that observe multiple objects at once given it's a phased array?
Time to brainstorm this.
Here goes nothing... First HAMnet hop in OK, currently
sitting on my desk, but hopefully it'll get mounted up on the towers next month.
We'll see how it develops from here onwards.
Out of 15hops, only a single one is via the public internet, between 0OZL and 0GW.
Yeah, I actually started typing the question with a H bridge in mind... But my brain quickly discarded that midway through the post lol.
What are those boards sticking out of the breadboard layout? Just P or N channel mosfets with a breakout?
Oh damn... Ok, I need to go back through my measuring procedure, i wonder if i made a mistake there.
Yeah but i meant it like, if you'll keep the Rb powered up constantly or not, as they take quite a long time (mine took a couple of weeks!) to stabilize enough to actually be better than GPS.
How are you going to power the Rb standard? I mean, are you gonna get an UPS for it or are just going to fire it up in advance of some important mission to track?

Some thoughts around a relatively new HAM radio digimode.
I managed to lose my LiteVNA... Fking great start of the year, that's for sure.!
Heltec LoRa V3.1 with Semtech SX1262, really a popular board for Meshtastic and other projects alike (cough.. Reticulum) seems to run on 23cm quite happily.
Still gotta measure the power, but atleast roughly from the field strenght it seems pretty close to the 20ish dBm.
Yet another AD9360 based #SDR got announced for crowdfunding today.... How many is too many, its all the f*cking same, all the same bullshit just with different APIs!?!!
Okay... Send it.
ARRL 10m contest is rapidly approaching, time to finish up all the prep work.!
Proba-3 data from @coastal8049.bsky.social's short IQ sample. It's 220k PM, 1/2 RS223 I=5.
Now... More data's needed!
We'll see, i gotta dust off (literally) my X-band hardware, i ain't sure where it all went... Heck might've even forgotten something back at the observatory from all i know🤣
Or, i'll reuse it on Ka.
Got a new bowl, but damn it leaks!
Anyway I hope @coastal8049.bsky.social won't mind that i'll reiterate over his MLD setup idea.😅
