@GreatScottGadgets Waiting for #URTI as my first #HackRF device. Other than that still in 💚 with #Cynthion for #USB hacking.

#hamradio I learned 433.775 12/125/5 is aprs on #LORA so must fetch some hardware for that!

OK, what application do people use for #SDR with #HackRF on an #immutable container-based distro like #UniversalBlue?

I've tried the SDRAngel flatpak (can't get it to see my HackRF device) and the CubicSDR AppImage (doesn't include its dependencies in the image; won't launch). Went to build a couple of others from source and zomg the dependency hell. If there are other flatpaks or appimages that work, I'm all ears, but I didn't see too many on flathub.

Gonna try a VM next, though the HackRF docs suggest it won't work. Maybe that advice is stale.

Selling a brand new #HackRF One r10 (the latest revision), because I’ve accidentally ordered two. Can send to UK or EU, full VAT invoice provided. Price €230 or £200, postage in EU/GB included.

Getting into gnu radio, wanting to put my HackRF to use. Want to actually get a decent understanding of RF theory.

Messing around with GPS signals, going to try to work out autocorrelation and things.

@Jochen_Jansen gibt ne Menge Zeugs in #ISM-Bändern:

27MHz, 40MHz, 150MHz, 433MHz, ... 2,4 GHz, ...

Viel Spaß beim suchen, ohne #Datenblatt des Tachos und nen #RTLSDR oder gar #HackRF wirste nix finden!

Ma première antenne, bande des 20m (14MHz) 🥳
Avec ça et la #HackRF one j'arrive à capter d'autres radioamateurs 😃

C'est une antenne ground plane. J'ai mis un simple bout de fil d'une longueur de 5 mètres dans un assemblage de tubes PVC. Elle n'est pas hyper droite, mais ça marche ! Au pied, 4 radians pour la mise à la terre. Et la courbe à l'analyseur de réseau est bonne¹. Plus qu'à finir mon émetteur !

¹ presque, étant donné que je mesure en 50 ohm et qu'elle a une impédance de 36,5 ohm

Welcome to the twilight zone where yesterday's classified intel becomes today's DIY project 😈🛰️ #DMSP #HackRF https://www.rtl-sdr.com/saveitforparts-receiving-military-dmsp-satellite-data-with-a-hacked-tv-dish/

@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...

A bad antenna is better than no antenna 🙂 #hackrf

So looking at the schematic of the #hackrf the component that I killed is an SMD size ferrite bead. Now I'm even more curious about how I managed to destroy it and the USB port(s) on my ham shack PC.

When I attach a coax to the HackRF while it is plugged in to a working USB port the unit does power up but there's no USB connection

My three theories are:
Unlikely: I was rooting around behind the PC trying to fish out a cable and may have pushed USB cable sideways, shorting it. The problem with this theory is that the short would have been at the connector. So this one is most likely bunk.

More likely: Before the HackRF died I noted high RF in my shack on transmit from my iCOM at around 75 watts RF. My HackRF was connected to my UHF/VHF vertical at the time and so I could have destroyed it with 75 watts of FT8. 😐

Also likely: Some sort of failure mode in the construction of the part itself that turned it into a resistor, it then promptly cooked itself.

Anyway, should be easy enough to repair but damn, I either need to practice better PC cable management and "choke" off this RF problem I have.

Thank goodness the HackRF is open source!

Kann wer einen #HackRF One gebrauchen und würde einen fairen Preis zahlen?

Das Gerät wurde wenig genutzt und ist in einem sehr guten Zustand.

Ich nutze Funkdienste anders.

Does anybody have really bad interference problems with the HackRF?

Mine is pretty seriously susceptible to both broadcast FM and USB interference. Here is a screenshot showing the sheer amount of stray harmonics - receiving in most frequencies is extremely difficult and getting anything out of airband is impossible. I also get a lot of signal mirroring.

Could it be faulty? I did buy it off aliexpress after all. But just looking at it, it seems normal. I'm going to make a broadcast FM and possibly wifi bandstop filter anyway

#hackrf #sdr #radio

Thinking about making my own SDR web server. I've got one main idea that I want to implement - replay. The user would be able to config a set of frequencies to listen on, and the server will record everything it hears. After a certain time period, say, a day, it'll flush everything for storage reasons, but this still allows a good buffer to go back and find whatever you wanted to go back and look at (kind of like a surveillance system).

Ce mec vient de découvrir l’option pour augmenter le gain en sortie de la #HackRF One de 11dB… Soit une multiplication par plus de 10 😂 🤦‍♂️
