Video

We need to see how the output is made available and then probably just find a way to convert it to cursory on target.

My brain isn’t fully awake yet but it was one of those “cauliflower” or FPV cam antennas I had installed on the hackrf when viewing the feed.

@@cemaxecuter7783 thanks for the reply. I am having issues finding "ATV" on sigdigger, does it come loaded by default? Or does it have a different name. I have some FPV antennas i wanna try out and might even make a video to help the next guy.

@MrKaleidoscope it does have a ATV portion to it but you have to open an inspector and setup for it. I think I have another video dedicated to doing so with SigDigger.

Please do ​@@cemaxecuter7783

If you watching just the control channel I’d think you’d just see station info. You’d probably want a channel that someone is talking on, I’d think?

Sounds like you’re feeding dsd fme audio though to see some activtiy. I really need to do a more through review of DSDFME because it has so many features.

@@cemaxecuter7783 ok thanks

I’m trying to remember, I think I had it in place on 20.04 but I may not have. It’s been awhile. Link me the video and I’ll check when I’m back.

​@@cemaxecuter7783 This is the exact title of the Video DragonOS Focal Running a GSM network in minutes (osmo-bts, osmo-bsc, osmo-bts-trx, USRP b205mini-i) , and its URL is czcams.com/video/6EnASi9MvSI/video.html&pp=ygUlZHJhZ29uT1MgKyBvc21vLWhsciBvc21vLWJzYyBvc21vLWJ0cw%3D%3D

I’ll try tonight if I get a chance. I believe the 978 docker can be configured for use but I’ll double check.

@@cemaxecuter7783 Thank you!

@@cemaxecuter7783 It would be great to have both for a complete picture of the airspace.

I just checked and at least the docker 978 is setup for just an rtlsdr and stratuxv3.

But wait the actual dump978 says it can use soapy and so the Airspy r2 shoukd work.

Can you give me a few more details. When you say python. Are you trying to use something like gnruadio and gr-bladerf? Soapy and python? I’ll try on my end, just want to make sure I understand. It’s possible I missed something.

FYI>> #bladerf hopper ver1 2014-8-12 import numpy as np import bladeRF import time # Ask for frequency range start_freq = float(input("Enter start frequency (MHz): ")) * 1e6 end_freq = float(input("Enter end frequency (MHz): ")) * 1e6 # Ask for hopping rate hop_rate = float(input("Enter hopping rate (hops per second): ")) # Calculate hop interval hop_interval = 1 / hop_rate # Initialize BladeRF device = bladeRF.Device() # Generate frequency list freq_list = np.arange(start_freq, end_freq, 1e6) # Generate frequency hop pattern hop_pattern = np.random.permutation(freq_list) # Transmit frequency hop pattern for freq in hop_pattern: device.set_frequency(freq) device.transmit(np.random.bytes(100)) # Transmit random data time.sleep(hop_interval) # Clean up device.close()

FYI trying beta36 now, oh i did notice the bladerf install seemed to forget files in /usr/bin? -update beta does not boot -drops out to busybox (initramfs)

@zerobow9413 most likely not a clean download or burn. Check the hash of the download. I’ve seen this happen a few times now to different people.

@zerobow9413 I’ll run through again and try the blade tonight.

I think so, but I don’t have one to make sure that’s true.

@@cemaxecuter7783 you have try with x40/xa4/xa9?

I believe so, but don’t quote me on it. I don’t actually have that model to try it.

From memory you have to generate certs but I also recall default ones being available. Can you remind me and if you have time put a ticket on the DragonOS source forge. I’ll try on my end.

@@cemaxecuter7783 I already generate the certificate and key (The server running fine), but the mumble server keep rejecting a request from qradiolink. I check the mumble server use TLS as a backend when code compilation take place, which qradiolink can't accept it. BTW thanks for the reply, I will put a ticket on this issues

I brought a lot of stuff with me so over the next couple days. I hope to be able to try it on my end.

I’m trying to remember, but are you using the vape or whatever it’s called thing that I included in dragon West or did you download something else?

You’d probably either use sdrtrunk or feed audio from SDR++ to DSDFME. I’ll try and do that as I need to get the pi image rebuilt and updated.

@@cemaxecuter7783 plz make a video

I’m not completely understanding, but I believe if you have the key for the channel, you can probably set it to receive all traffic. I’m meaning to get back to this as soon as I get all caught up.

@@cemaxecuter7783 Yes. I have it now open on all types (longfast, long medium, etc...) but not receiving any messages, even if i am in a big city where i know meshtastic is really active. I want to know if i have to setup smth that i see public discussions. Or do you always need for that keys?

That is partially correct. I will be adding the docker containers like you see in this video but I’m also working on a model that has it SDR that could run it. Currently the WarDragon does have everything that dragonOS has, but it only has an AIrSpy SDR.

@@cemaxecuter7783 Thank you for your reply, let say tommorow the WarDragon arrive in my home, if i want to run srsLte with my own USRPB210, i just simply plug it and run the srsepc and srsenb without no need install anything in my side right ? (i dont need to install UHD and no need to build srslte) because if ever i buy my first goal to run that, im still think and considering to buy it (will check my budget etc)

Thanks for dropping in! Hopefully you find them helpful.

I thought I replied but it must not have sent. I was letting you know the hackrf is only half duplex and cannot send and receive at the same time. In the video the hackrf is sending the meshtastic and the Airspy SDR is receiving it.

@@cemaxecuter7783 Ah perfect. Thank you for that answer. I appreciate that you care here in the comments. Then i will maybe lookout for an airspy or dirctly get a meshtastic ready device. Your video is really cool - im thankful for the good explanations. Thanks Dude!

I keep meaning to do an update for that particular platform. I’m glad you got it running. Hopefully I can get an all new image together ASAP.

There’s a GR-AOA for angle of arrival and I think SDR Angel may have the same as well. I have to check. Would be a good subject.

DragonOS has dumpvdl2 included. That shouldn’t be a problem. I’ll look around for a video as I think I did one showing how I got mutiple things going at one time. But just dumpvdl2 on its own can run with an rtlsdr.

Ok thank you. When you say that DumpVdl2 can run directly with an rtlsdr, do you mean within Dragon OS?

@andrewlincoln9766 correct, but if you want to use it on say windows, you could use it within a docker. For example (this is from my Linux repo) github.com/alphafox02/flightview_gui/blob/main/docker-compose-dumpvdl2.yml But on DragonOS it’s just installed native and available at a command line prompt. You can also use sdrplay equipment. I need to check your original message, you’re intending to use DragonOS or something else?

@@cemaxecuter7783 I would like to run DumpVdl2 in Dragon OS using the RSP1A or RTL SDR, I just need the command line details to setup/run it. Also I would like to try running DumpVDL2 in Windows 10. How do I set that up and run it

@andrewlincoln9766 for DragonOS have a look here github.com/szpajder/dumpvdl2?tab=readme-ov-file#basic-usage You’ll find command line examples for rtlsdr an sdrplay. Just start it with dumpvdl2 and not ./dumpvdl2 and use the remaining part of each example, that’ll get you going. In windows I’m not familiar. A virtual machine of DragonOS, docker, or WSL is your best bet.

I probably overly complicated the video, essentially if you do the following git clone github.com/alphafox02/flightview_gui Follow the guide in the readme to install docker then just docker compose -f docker-compose-node-red.yml up It should start up node red. You’ll also notice I put the example flow json in the directory. You should be able to piece it together. I’m honestly trying to work out a way easier method asap!

​@@cemaxecuter7783Wow I got it, thank you! I see the new subscriber on Sniffle and NodeRed map is open. Now to wait for a drone to fly by... I still needed to remove the docker image and retry it, even though it was a fresh install, so glad you left that in there.

@ericks1979 was this on a WarDragon? I only ask cause I emailed out a new base image. If you’ve restored to that image it should’ve had the new node red and everything setup. Just curious.

@@cemaxecuter7783 no just FocalX R36 on a Toughpad

​@@cemaxecuter7783 no just FocalX R36 on a Toughpad

Glad it’s helpful. It’s been a blast along the way.

Can you shoot me the details on the screen? I never did get around to trying out screens besides a normal monitor but some people in the source forge discussion/ticket section got a few working. This also reminds me, I really need to get a chunk of time and update the DragonOS Pi image.

Interesting. So I’ve had dual boot with windows being installed first and then Dragon. I think at one time I had mutiple dragon installs (lubuntu) but I’ve not tried it with any other combo of Linux. I wonder if the already existing grub is getting messed up?

No idea. I watched another dual boot installation video where they guy did manual setup instead of guided and then selected the partition he had just set up to house the boot loader. I’ve got windows and Linux on two partirins, trying to create a new unallocated space to house dragonos, but struggling to understand what to do with grub/ bootloader.

So now I can get Ubuntu boot loader up also showing windows but im loosing my second Linux partition that previously worked with grub… 😬

@williambarnett7518 see I do remember somehow like this where the second instance of Linux wasn’t seen.

This was actually the one video that didn’t have audio, it was made in haste from what I remember. But thanks for reminding me of this because id like to redo it and try and come up with a better use case.

I do recall maybe getting it to work with the hackrf on 20mhz but the source block needed changed..I’ll have to take another look.

I’ve managed so far to detect the remote ID over 1km away when it’s the Bt5 Long Range type and that’s with only an 8db small Omni antenna. I suspect it can be received much much further making it likely more relevant.

Like you said though, it’s probably to have something in order to detect if a drone or drones are in unauthorized areas, but only if there’s some device locally there set up to receive. I just think I can extend that range way out for more of a protective measure of sorts.

Sorry for so many split replies. The last thing I was gonna say was I have a spot picked out that’s several miles line of sight which I was going to attempt having a directional antenna and see if I could pick up the remote ID.

@@cemaxecuter7783 More relevant to who and why is the question. If there is no ATC for drones why track them in such a limited fashion? . not a fan...will never comply as I fly alone quite often and have been doing so safely for 40 years now..I don't want local thieves or karens to even know I'm anywhere near them because they used a phone app to track me....All this has done so far is leave the big park I fly at that had 20 flyers at times empty...seems most took up the few available spots at the traitorous AMA clubs ...others flying in different places because they fear being fined for flying toys in such a large venue or given up the hobby altogether..I reckon the field was too crowded anyway..good job FAA/ AMA.. 👎🏼

Shoot me an email sometime. It’s up under the CZcams about section. I try to monitor it. I do plan on being there! If your outside the US I will have to coordinate some kind of shipping arrangement, but if your in the US you can grab it from the cemaxecuter.com site. I have a bunch of the full kits I’m working on now.

The person that did the fork is actively working on an SDR port. That’ll be super handy too!

Bt5 operates in 2.4ghz well outside range of the rtlsdr. However, the developer of the modified repo is working on porting things to an SDR (would need the freq range of course).

@@cemaxecuter7783 Oh I didn't know it was 2.4GHz, hopefully the developer you mention finish it soon for HackRF or BladeRf , thanks for the reply btw

@314Show no problem, I think the sniffle original developer is also pursuing a SDR version, so I think we will see some great stuff soon!

Not sure what you mean. You installed in virtual box or you’re running it live in virtual box ? If you’re running live the user has no password. Try and leave it blank.

SDRAngel can live decode a 5Ghz analog drone feed. But that’s what I cover in this video. I can’t think of anything else off the top of my head.

That is only for specific DJI drones that transmit DJI drone ID. Not all DJI models do and to make matters worse, in recent firmware releases DJI has started to encrypt DJI Drone ID, so the decoding process won’t work. I’m having help to make another way of decoding different ID info from Drones. Hopefully that will be available soon.

Either or should be fine

It’s often too low a signal you’re receiving, you can also try to move the slider a little left or little right on the GUI, but most likely you’ll need to reposition location or get a higher gain antenna for that frequency. Assuming you picked that freq cause of output from the scanner? I’ve often got results from the scanner only to find livemon produced no results till I upped the gain setting I was passing to livemon, moved my antenna around or changed position.

@@cemaxecuter7783thanks for your reply! I want to do is to capture the hex code of the USRP b205 mini receiver antenna via DragonOS. I would be happy if you could explain in sequence what I should do in this regard.

I don’t believe so, but you can try. There’s no GSM at that frequency though that I’m aware of, but if for some reason there is and it follows the gsm standard, maybe it’d work.

I’m not finding an easy method to have the sinks made on boot yet. I’ll keep looking. Using the manual method for now is best.

This script or the commands in the script could be used in a terminal to make the virtual sink(s). You could also setup the script to run on login.

@@cemaxecuter7783 Thanks. I*ll give it try.

🤦‍♂️😂 I’ll fix that.
