Usually the biggest problem with getting things like this to work is figuring out all the dependencies. Many times you will find that dependencies either stock loaded or available to a full system install (laptop, desktop) are different for RPi. A lot of major dependencies have been made for the RPi you just have to manually install them. Usually you can get them working just have to do some digging into it.

Have done similar with RPi. Can use SSH and VNC to run it from about anything with SSH and VNC apps available.

I would do some serious digging around the web for more information about the drone. You are going to need to know the protocol and what commands are required to make certain functions of the drone work. If no one has done it before and the company will not respond/share information on the functioning, it will most likely require reverse engineering the drone to find all these thing out. If the drone has a FCCID on it that might help with information on the data communications part of it. It can be surprising sometimes the information found with an FCCID search. Also posting all known information, like FCCID, on the forum makes it easier for other interested people to help!

I think one of the funniest interference cases is when an ISP puts all the SAME WiFi routers on the SAME channel in the SAME town and a lot of people are mad about poor WiFi signal. Its bad enough when a low quality router is used, but simple channel delegation can help quite a bit.

Good site. If your looking to get started I would give it a try.

Part of the reason I got into it. One of the best things about HAM radio is there are endless things to do. Different bands, projects, hacks, tweaks, challenges, etc, etc, etc

I would put this project on your to-do list for raspberry pi projects!

With the setup you have Kismet would be the easiest to start with. There are other programs that can give more information but not really needed to monitor one ssid for signal strength only.

This is correct for RF with no interference. Like others have said, you must be getting off band interference. There are so many things that can cause it. Bad transforms, older cordless phones, older home wiring, harmonic interference, etc, etc Just have to start eliminating things and it will eventually show itself. Of course a RF spectrum analyzer would make it easier!

Sounds like you want to do something like a linear transponder or repeater? Some more info on what you are trying to accomplish would help give a more specific answer. There are ways to use two SDRs at once but again what exactly are you trying to accomplish?

I agree with what your saying. Just thought I would bring up that there are a few rare cases where it might actually be in the gray area. The black vans showing up would depend on how far and whose devices you ended up jamming. The even harder part to stay legal on "jamming" a drone is if it is using any sort of rolling code, encryption, frequency shift, etc. You aren't supposed to broadcast a signal with encryption except in some rare cases.

I can see this being a fair argument.

I suppose I should have went into more detail. "Jam" a device no. But there are documented situations were a a ham radio operator is not doing an illegal act if operating within a frequency range and power level of a band, with a "broadcast signal stronger that another device" that causes a "jamming" type situation. I know this just sounds like a wording game but its more of a technical matter in the radio world. One good example is the use of OpenBTS to make a cell tower. There is nothing illegal about it on the right frequency and power levels allowed to amateur radio operators. It becomes illegal when it has malicious intent to force users to a tower used for eavesdropping, etc .

Haven't used one myself but hear good thing about them. Been wanting to actually looking into setting something up similar. Use to do some HF WeatherFax. Fun to mess with sometimes if you have the right radio equipment.

Agreed.

There are some builds that can be found online for drone jammers in these ranges (mainly 5.8 GHz). Most of the time when it comes to jamming that's true. It might be possible with a ham radio license ? But hard to say for the linked devices since the specs aren't very in depth.

The AWUS036H has been a long time reliable adapter. I recommend the AWUS036NH with rt3070 chipset if you want N support and newer chipset than the rtl8187 (still been around a while). Some don't like the AWUS036NH due to no 5 GHz but that just depends on your needs really. I'd really like to give AWUS036ACH a go but haven't seen a reliable guide showing good support of the adapter.

I see this a lot, and several popular programs have issues with the rtl8812au chipset. I prefer the AWUS036NH if you don't need 5 GHz. Works right out of the box with kali and good support. Never have had to load a modified driver for it. But I know, it doesn't support 5 GHz....

I would do a google search to find some good info on updating the driver to hopefully resolve your problem with the adapter. Several good sources can be found.

What version of kali are you running? More than likely a driver issue. The AWUS036ACH supports monitor and injection but from reports on other forums there is a lot of driver issues. I personally have not used the adapter, but have seen people report the kali default driver does not work and requires updating.

Here are some version 2 photos. Let me know what you think! New features include: 30% reduction in overall size new CNC router cut mount plate External Ethernet port new thinner fan grilles (CNC router cut) removed almost 20ft of cabling with custom USB cables to all devices and shorting of power wires. There is additional room in the enclosure for some soon to come updates. Also going to cut the fan openings into the enclosure with CNC router for a sleeker look as well. Going to use a slimmer Ethernet port (just used the one I had). Still working out the battery pack but hope to finish up its design soon as well.

AWUS036NH has some of the best range wise of usb adapters for 2.4 GHz that I have tested. A lot of times it seems to have stronger signal than other adapters, not necessary more APs.

If you have a particular goal in mind for the adapter you may want to check that it is compatible. Like @Dave-ee Jones said, a google search can give you some helpful information from other peoples experiences.

Did you install the heat sink? Pretty sure none of the awus036h had heat sink on the chip from factory. Here you can see the two board revisions. https://wikidevi.com/wiki/ALFA_Network_AWUS036H

One feature you have to keep in mind is the dual radios. Info can be found on the Wiki https://wifipineapple.github.io/wifipineapple-wiki/#!hardware.md You might be able to load the firmware but without the compatible hardware features will be limited.
