Some comments from the perspective of someone who has taken crossfire out to 121km on a 1.3kg FPV plane: 1) 900 MHz and 1.3ghz analog (still #1 for pure long range) really mess with each other. I run additional notch filters on the video receiver - which already have good filtration to begin with (rmrc brand). On top of that I relay my RC link and video link so I can have each on their own tripod spaced out by 20-100 meters. Even still I see the blips of 900 MHz interference in my video at extreme range. On the RC receiving end of things - I run Matek 1.3g vtx with selectable output power. I avoid the highest power setting when possible (800 mW) because in some cases you can watch SNR db drop on the RX link with increased video output power. This probably has more to do with fresnel zone interference which impacts both video and RC link, placing both on the edge of failure to begin with. Still, it isn’t fun to clear up static with increased vtx output - only to instantly Send your RC link into failsafe…. 2) Having the RC transmitter on a tripod - wirelessly linked to your transmitter is fantastic for long flights. It could in theory be done in the opposite order but you can run say…. Tracer on your radio. Then have the tx pad of your tracer receiver wired to the RX wire of the CRSF input on your 900mhz module. This obviously adds latency and you will never have telemetry - but for long range FPV - it’s fine. Then you don’t have to care how you hold the radio - you can go piss behind a sand dune with your goggles on your forehead, holding the radio by your side…. Just saying…. 3) As to how 1.3ghz video and 2.4 ghz RC play together? Idk.. never tried it - but I want to. As you pointed out, antenna size is massively different between 900 and 2.4. I only use a shapeshifter for my 900 long range setup - so not very directional…. For that same size - I could run a 9-12 db yagi on a 2.4 ghz module. This really would help close the range gap between the two frequencies. No free lunch of course - as the high gain yagi is very directional - but so is my Long range flying… I know what course I will fly within a few degrees days before I fly it - because I plan it that way. I set up my tripods with a compass - directional isn’t an issue for me. Maybe for others it is…. Idk… Cheers and thanks for the good vids as always.

And with the Tx16s I can later upgrade the ag01 gimbals and can upgrade the fatshark scout with rapid fire. Seems a good way to start and not have to upgrade for quite some time and still have a decent rig. And I’ve figured out I’m probably gonna own several quads and fixed wing fpv craft.

If you're interested why lower frequency have better range google "Friis transmission equation" (look at images where Pr = ...). It basically says that received power is proportional to wavelength squared, aka if you lower frequency by 2x the received power increases by 4x (if I understood it correctly)

[@icp-trek]

Good video Joshua. For the viewers and readers, if you got a radio link that works for you and how you fly, you don't have to change. There is no FOMO here. I'm a confident CRSF flyer and mostly do mountain crusing. But I confess, the huge antenna (900Mhz) is a hassle. Monst of my quads use the L-shaped style. Some the horizontal style (but I prefare the L-shape cause I can avoid the nulls. If it's working, don't try to fix it.

This is awesome. The range-vs-wattage-vs-frequency approximation testing at the end were really cool, however I am not so much interested flying long range...

If this test could be performed with signal PENETRATION in mind, it would answer more questions for my use case. Regardless, awesome video and cool to know where upcoming tech is headed.

Thanks, Mr Bardwell, this has kept me wondering for a while (900Mhz vs 2.4Ghz). What should we do with our old 40Mhz gear? The submarine-modellers still use it as well as some antique modellers... Perhaps give it to them. By the way... for ELRS I will probably stick to 150Hz Packet Rate, still feels very good and responsive.

There are folks playing with 144MHz ELRS, that'd probably work well for the submarine folks.

[@BooDevil65]

Great info, as always! I'd be curious if your results change if you moved the devices further or closer - in case one was benefitting from standing waves (ie at a node vs anti-node)

[@conorstewart2214]

For most people it seems like the 2.4 GHz will have more range than they will ever need anyway, even at the 100 mW limit in the UK and EU, it seems the main need to go to 900 MHz is if you fly extremely long range, 10s of kilometres or more (even though the 2.4 GHz ELRS can apparently reach into the low 10s of kilometres) but like you mentioned that is illegal in most places. It would probably be a lot more useful once it can be used with fully autonomous drones but again flying those long range is likely illegal. In a lot of cases pilots are already breaking the rules on LOS and transmission power, pushing for 10s to 100s of kilometres of range just seems like a way to definitely get noticed and caught out. It is one thing to fly behind some trees or a building or to fly FPV without a spotter, it is another thing entirely to be flying 10s of kilometres away from you. If your drone can still receive signals and send telemetry then anyone else in at least that range of you or the drone can pick up those signals too and the higher power you transmit at the more likely you are to interfere with others and hence the more likely you are to get caught. If your drone is 30 km away and sending telemetry then anyone else within 30 km of you or the drone could receive those signals too, ignoring obstacles. I know they probably won’t be able to decode or interfere with your signals but if it causes disruption then it could even lead to stricter laws. As is the current advice anyway, keep it away from others where possible or keep it legal. Also very long range drones are large or fixed wing and are therefore easier to spot. The 2.4 GHz advantages over 900 MHz are probably enough reason for most people to stick to 2.4 GHz, the lower latency, higher bandwidth, smaller antennas, etc. It would be interesting how the range and power of ELRS (both 900 MHz and 2.4 GHz) compares to the range of DJI drones or air units with controllers and which is best for penetration.

[@ZeroFPV]

They have a "Long Range Competition" site on the ELRS website. The record for 2.4GHz is 40,6Km @ 25mW. So at 100mW you could get over 80Km range (4x the transmit power = double the range). I can't imagine that any country which limits your transmit power to 100mW does legally allow you to fly such distances.

Joshua, Mavlink is a pretty verbose protocol; it doesn't use compression and always resends all the data (no incremental updates). So, it will be pretty challenging to make it work over 900MHz with its bandwidth limitations. 2.4G ELRS is a much more suitable candidate for a Mavlink bridge.

[@Vousie]

The SIK radios (and RFD900x etc) already do bidirectional telemetry on 900 MHz, so it definitely is possible and works very well. Though it still would be great if 2.4G ELRS could support bidirectional mavlink with the RC. Eg something like ELRS airport, but with RC still available. You usually don't need as much uplink bandwidth for mavlink anyway, so taking some of it out to use for RC would be fine.

the way I understand the relationship between power and range is to imagine a sphere. The volume of the sphere is the total output power, the radius of the sphere is the range (from centre point to any point on the surface of the sphere). for example the radius of a sphere with a volume of 10 is 1.34 double the volume to 20 and the radius only increases to 1.68 its not the perfect math for this, but it's a good way to picture in your mind that doubling the power doesn't double the range.

Unless you have directional antennas?
