SIGINT, ELINT and comms for the individual

I want into SIGINT and comms, I know the very basics of comms, I read NCscout book, now I'm watching some YT courses for ham radio and S2 underground.
i got a vanilla baofeng uv5r, it would be good to develop the listening post concept to monitor signals around me, I saw the hack rf one in S2s video and it seems good as a standalone receiver for almost everything, and also has capabilities to do cooler stuff that I don't even know now.
so yes give me some info on where to go look to learn and what to do

    get a hackrf its the swiss army knife of basic SDRs

    or you could get an RTL-SDR which is much cheaper but has lower specs and cant transmit.

    I highly recommend looking at defcon stuff to get into this. Packet hacking village and wireless village have lots of instructional material.

    to add to this, I'm also becoming my journey into trying to have more privacy and opsec for my life in general, like leaving less trace on the internet and making it harder to be spied on by the police if they wanted to

      which one of the several hackrf available is the best one?

        Get one with the portapack. Its a lot more useful that way. The github page for Mayhem recommends this one:
        https://s.click.aliexpress.com/e/_DmU7GQX

        You should know a thing or two about amateur radio before getting in to something like this. Is you jump on a HackRF without ever having used an SDR or even a Baofeng before you'll have no clue what you're doing.

          I used baofeng although i havent done that much with it, but managed to find an unencrypted police frequency so I can listen to them which is cool, btw anyone knows why periodically theres a beeping bopping sound and then the operator says "checks are good"? inassumenthere sendingbsome kind of signal that gets identified by the controller to make sure it's them or something like that so the radio signal gets translated into audio and i hear that

            Police radios, even analog ones, use trunked systems to allow for a bunch of radios in the field to talk back to a central operator without everyone hearing everyone else all the time. Modern digital ones are able to channelize stuff but the older analog ones will use tones and inaudible carrier frequencies the radios can pickup but you wont hear to do it. Without knowing more you are probably hearing something related to the trunking system.

        All of the knock offs cut corners and generally are worse on both the TX/RX. If you must have a HackRF, buy a legit Great Scott Gadgets one (I say this as the owner of multiple of both the original and it's clones).

      Did you change your DNS yet? First, make it not your ISP.

      Second, set up your own DNS server on a resperryPi and a flashdrive.

        no dude I'm ignorant as frick on actual computer cool guy shit, I know how to use them well as a user if I have to fiddle with shit etc but that's easy to do, but I realized how everyone uses electronic systems as part of every day life without much thought but how much they can spy on you.
        like the other day my father was pulled over by the police bc his car broke in the highway, and the police started asking him personal shit they knew about, some of it is easy to explain bc my mother sued him so they must've saw his file on their archive and seen the thing, so they asked him about my mother and shit, but the creepier thing is that they knew that he had already been in that place he was at that morning, and even knew why he was there, so how tf can they know that, I mean yeah phone towers or idk even phone localization but how tf did they know the reason, maybe his phone is listening idk

          Your phone is tracking your location all the time. This is by design and is part of the 911 system. The same goes for your car if you have any service that broadcasts out such as on-star. If you are worried about being stealthy, take a few courses on cyber-security then start worrying about all the smart devices you have around you that are sending data back to their masters. Don't worry about some feds in a van, worry about your smart TV and game console spying on you.

            btw im not in the us but Europe, but I assume many things are the same, but again if they know where you are now it's one thing, but they knew where he had been that morning, and even the reason why

              Regardless of where you are, you are being tracked and spied on by your phone, your car, any smart devices you have around you and any video cameras out in public. Your local police have probably labelled your dad as a troublemaker and are keeping him under casual surveillance. They may have let him know that he is is being tracked to scare him a little so he stays a good boy. Oh, and the data they collect is shared if anyone else asks for it.

                you mean the police or the devices and the owning companies of such devices?

                can they actually listen to your conversation with your phone?
                I mean I know it can be done, but can the police actually go that far and do it, both in capabilities and if it's a procedure they follow normally for investigations like in this case.
                bc my dad is a tard for this a just casually talks in front of the phones even of stuff he shouldn't say, idk maybe they're even looking at my phone since I live with him.

                I have no idea where you live or what your local laws are. In the US it would take a court order and be only for a specific purpose and for a limited time. Countries line China track everything about everyone, so absolutely no privacy there. Perverts also hack security cameras and baby cams in houses to spy on families. 80% of the port cranes in the US were make in China. It was recently disclosed that those cranes have back doors for surveillance and possible remote control. I would assume everything electronic made in China has a back door until proven otherwise.

                Legally, which means what is found can only be used as sirect evidence in that case.
                But I wouldn't presume that means it is not done illegaly for intelligence, and they just cannot use it as evidence.

                Many smart tvs even have cameras some behind the screen. The official reason is to adjust the screen based on viewing angle and similar things. Many smart remotes have microphones.
                Well the CIA was using them over a decade ago to watch people. Whether a company says they patched them or not the hacking is only better now.
                Anything that can send a signal wirelessly or is plugged into the net should be presumed compromised until you know a lot about it.
                Even many things with 0 internet access communicate passively with things that do have internet access.
                Alexa and ciri microphones were found to always passively listen whether called or not and the gathered data was used to improve ai according to the companies. That is just what they admit to.
                Teslas and many modern vehicles have multiple cameras, and then are plugged in for charging and updates regularly. On star and similar services even when not subscibed to can passively spy and even enable remote access. Presume they send data of everything and everywhere and everyone they have been around when connected for updates.
                Every phone has both cameras, mics, and various sensors that can detect ambient light, motion, orientation, and all this info is remotely obtainable.

                Many house appliances, and electronics, household security systems, etc also spy. Even when not online many talk to things that are note thier presence and report it home.

                Then facial recognition and license plate reader caneras all all over in society, with ai increasingly added to track and generate data on movements of everyone.

                Is a lot more.

    no it won't. it's slow at scanning and you will have to program the channels, which you don't know beforehand, if you want any chance of catching something
    better get an SDR so you have nice visualisation, long term monitoring capability and a nice interface on your computer screen
    the rtl-sdr will outperform the hackrf. just not in total bandwidth

    Common commercial SDRs have something between 1MHz - 50MHz instantaneous bandwidth, you only need a few MHz bandwidth to monitor any one common VHF band. My opinion is that you should get a handful of cheap SDRs to cover all common VHF speech bands that people are likely to use, wouldn't even be particularly difficult to program really. In the future (10-20 years from now) you can probably get cheap-ish real-time spectrum analyzers that have the capabilities 50k$+ signals intelligence receivers have now, which is DC to microwave instantaneous bandwidth

    Thanks to S2 underground, I recently got into comms as well. Got myself a couple friends some baofengs. I went through and programmed all of them for some basic channels, NOAA weather channels, and all the repeaters in our area. It's a good start, but I work in police dispatch, so I well aware how outclassed we are in radio to radio communications. That being said, they're fun to frick around with in the mountains when we're larping.

      Yeah,handhelds are a great starting point.There's a lot of cool shit you can with radios.Anyone with a computer should pick up a SDR and see whats out there.I do police scanning,pocsag pager decoding,slow scan tv,wefax weather,plane tracking,etc. I always have mine running because there's always weird shit being broadcasted,and reception conditions are always changing,so you never know what you'll find.
