Basically, or use a fiber optic drone

How many 20 MHz bands are there? One would have to turn on a powerful jammer to jam them all. But then it would become an easy target for anti-radiation drones.

@@eugenedsky3264 there’s only one… hence the name 20Mhz band.. did you really just ask this question? And yes the Russians have a vehicle mounted drone jamming system equipped with battery backup it’s strong enough to jam American airplanes out of the sky if you read the news articles. Just need high power, with enough amperage theoretically you can create a jammer that jams every single frequency in the spectrum

​@@Antonnn1111 The so called S band (frequencies from 2000 MHz to 4000 MHz) contains 100 (one hundred) 20 MHz bands. Not all of them can be used by a single radioelectronic chip in a tranceiver, but you get the idea... Не пиши чушь... Also you can use not only frequency-hopping spread spectrum (FHSS), but time-hopping (THSS) too! I.e. you can make your RF pulses much shorter and give them more peak power with the same electrical power source (battery, generators, etc.). Thus you make such a link even harder to jam. Also don't forget about autonomous and semi-autonomous drones (guided artillery shells), which can bomb an enemy location with its coordinates given in a 3D map or in a local positioning system (LPS) based on ground hyperbolic radio-beacons synchronized with compact atomic clocks and corrected every 1-2 minutes by a test drone... Questions?

@ I thought by 20Mhz you referred to the single frequency

Second that!❤❤❤

This is what the Ukrainians are using, some of them. Saw a video where they send out different drones on diff frequencies to prevent the Russians from jamming them

most likely a fork with a closed source firmware bootloader, id hope they’d encrypt telemetry

Yes, but they break in the process.

Completely different roles

Is dji drones immune to jamming? Can they operate in a GPS denied battle field?

​@@pandibbarman they return to source when jammed. Pretty much blind.

@@beginnereasy No they can't a lot of videos of them just falling out of the sky after being jammed

@@pandibbarman mm makes sense no gps data

We can make our own

Probably like the MPU5 systems. Those are about $30,000 + depending on options. That's for just one radio. The Internet gateway/bridge is probably 3X that given what I have seen from other similar systems.

@@jordani3015 Meshtastic + Reticulum is the best you can do right now.

These seem to have US military applications, so fat chance that will ever happen and will be restricted for export. The strategic implications are too great.

You can find the internal boards on Mouser (part no. 332-RM-1700-22M3) if you want to build your own. It operates on 902-928Mhz and 2400-2482Mhz, which are unlicensed frequencies. Get your local machinist to mill you an aluminum housing. Install control buttons, a battery, and antennae. Get at least one friend to do the same, and you're all set.

@@waylonk2453 Or, just buy the Lima boards these are built on

​,if you don't have access to machine shop or printer it's not that hard to laminate materials into a even more suitable container with a little skill and a few hand tools.

right, they don't have prices so maybe not to the public

Great q! It does not, rather: - DJI sends video feed down to GCS on the ground - GCS is connected to Wearable Mesh Rider Radio via Wi-fi hotspot backhaul - TAK UAS plug-in grabs and sends video as a broadcast across TAK, which can be viewed by everyone on the Mesh Rider network. Additionally, since we also backhauled the network into Starlink unit that was mounted on the response vehicle at the base of the foothills, that TAK broadcast could be seen by anyone logged into the TAK server anywhere in the world. If Corona *had* been operating a drone with an integrated Doodle Labs radio (there are many great options out there!), that video stream could be routed even more directly, and the drone itself could act as an aerial antenna and increase the reach and resiliency of the network for folks on the ground.

@@doodlelabs yes that makes sense, in would be strange to have a radio integrated into the Dji. Also as I got your attention it would be great if you could upload a tutorial video on how to run 3rd party scripts in the radios.
