[@michaelreyes8670]

Great very informative video. For a FPV noob, there is more to it than just powering your FPV quad. There are sometimes an FPV race going on the other end of the field I'm flying on. Thanks for sharing.

[@rcwck]

This stuff was the BIGGEST pain the arse when first starting our FPV group. Most didn't know what channel they are on or how to change to a specific channel. We are trying to put everyone on Raceband and that seems to work the best. People with that 600mw VTx is a continuous problem and mostly have to fly pretty much alone. A couple people have been testing the $12US Eachine VTx03 with good results. It continuously blinks out powa, band and frequency. It only has a dipole antenna but seems to matter not. The best tip before powering up is too turn on your goggles first to see if anyone is on or near your channel.

[@TheDriss567]

Great vid, great info. Thanks Joshua. happy flying

[@lukegodeassi7352]

Thanks for making this video, I'm going to point EVERY new pilot to it from now on. We've all done it when we were new, but there really is nothing worse than being knocked out of the sky by someone powering up 2 feet away from you on 600mw.

[@brimmlessyankee6980]

You mean mv?

[@FINShotguN]

We have a terminal for the transmitters to be able power up and change channels while others are flying. Only negative side of that is you have to take out your antenna. Some have them directly soldered so they just gotta wait untill everyone has landed.

[@PerchEagle]

I hope you do a video about RF fundamentals, what is the shape of a basic RF signal, carrier signal, encoding and decoding for different applications, radio stations, mobile phone transmission and of course a hobbyist who use RF for the quadcopter ... etc.

[@alfredosaugus705]

i holler power up/down even flying by myself. just makes it sound official. respect the drone.

[@G6EJD]

The problem your describing is due to poor co-channel performance of the FPV receiver. The effect your trying to describe is not due to the diversity algorithm it is due to automatic frequency control of the FPV receiver. The advice to reduce RF power is good and your command link cannot be affected in the way that FPV is as the modulation is different and the link is typically frequency agile.

[@1grizzlyrizzo]

Thanks for another great video.

[@gonzobanjax8857]

Hi Joshua, can you please explain the purpose of the Taranis EU version advertised on at least one website. Also, a tutorial on the different FrSky receivers and their applications would be a fine thing. Thank you for producing this wonderful channel. Regards, Andrew.

[@lukegodeassi7352]

As for your teaser about LaForge vs True-D in terms of rejecting interference, I'm going to put it out there in advance that I think the LaForge will be superior in this regard. We race 8 in the air regularly in my local group and those using the LaForge have noticeably less issues than the True-D users with a densely packed RF field.

[@taterchipfpv9162]

I would agree, I consistently can fly in spots others without LaForge cannot....

[@christianmoreton9326]

Laforge and liking it. I am a huge fan of the youkits antenna analyzer for HF antenna tuning, I'm wondering if there is a way to do the same kind of sweep across 5.8ghz, to find the most resonant frequency of an antenna. I'm curious how much the frame and surroundings affects impedance, but can't seem to locate any gear to make that sweep in 5.8ghz. I might want to try an antennas with a very high Q.

[@JohnFHendry]

8:28... yes, your video power level should be as low as possible for the best signal reception to avoid adverse reflections and swamping your 2.4gHz RC link with interference reducing your RC range. I recorded my DX9 that has always exceeded it's range tests lose it's connection with a UMX Radian also range tested while a goggle mounted non-diversity Fat Shark 5.8 VRX using a (genuine) IBC Mad Mushroom antenna received a clear signal from an FCC stamped 25mw 5.8gHz TX transmitting from a few hundred ft up to almost half a mile out in lift OVER and past the same building affecting my 2.4gHz signal distance! And before that I watched the same thing happen with another well tested 2.4gHz RC TX at very close range when a building blocked my ground stationed 2.4 transmission but the same type of 5.8 25mw VTX/cam with clover L antenna showed me even while out of line of sight by a few feet where it was landing. The DX9s antenna has both vertical and horizontal polarization in the form of a half wave center fed dipole antenna system but it still could not communicate with the UMX Radian dispute having the advantage of being a lower frequency and having over double the transmitting range distance on paper. Ever since that seeing the advantage of transmitting higher up and having circular polarization I don't think in terms of adding more VTX power to increase my 5.8 range flying on 2.4gHz as much as paying attention to more important considerations because I want the video to go out before the RC link as I fly mostly downwind where I'm at and fail safe won't help much to bring me back in range on a good day.

[@joe8663]

Hi. So, I have a ham license, but got it a few years ago, and maybe a bit rusty. I'm thinking of getting into fpv, though for rc trucks not drone (at least not right now, maybe in the future though). Anyway, my question is regarding what the actual requirements are for fpv? Searching for "fpv staying fcc compliant" gets me page after page of people saying "yes you need a ham license". Im assuming the only real requirements are use minimum power required to operate, and verify you're allowed to transmit on that frequency. But, its a black box to me, and the last thing I need is an fcc fine, or to put my license in jeopardy. Is there some resource for making sure my ducks are in a row? Also, I remember reading something about being required to transmit your call sign periodically, or having it embedded in the broadcast. Is that something I need to do?

[@alienfleet3702]

One other point is power output not being the same on all VTXs. 200mw VTX that actually puts out 600mw, for example

[@JoshuaBardwell]

Both of these were TBS Unify FWIW.

[@DutchRC]

I was hoping this video would be about that momentairy glitch on power up.. I suspect there is a difference in amount of that glitch between VTX's.. Have you ever looked into that? (say between the Boscam's and Fatsharks etc...)

[@SuperG316]

Today just watching race. I commented in a regular forum that wenn fetch yourt quad pull power off before you come in pilot zone. etc. But at that race a pilot landed in the pilot zone where other racer saw his feet instead his signal.

[@leitmanr]

Thank you for this one.. we have been trying to figure this out for last week.. I have one question.. does it make a difference to have ie. TBS Unify or random cheapo BG VTX, considering only the "width" or "frequency footprint" Is TBS more accurate when transmitting on certain freq? We have found out that those bg vtxs are blasting on almost half the spectrum and had trouble to get 3 people flying together.. now we are considering buying UNIFY RACE vtxs but they are sold out everywhere :( But trying all your tips here (distance related) will help for sure.. we had our lounch pad like 5 feet from us :D everyday we learn something new from you.. thank you for all the effort you do for us newcomers to the hobby :) is there any chance of Part2 of this video? more on the harmonics for example. Thank you..

[@kawsper]

Hopefully when the OSDs and SmartAudio gets more widespread, the vTx can boot up in pit-mode as default, which will let you configure frequency and power before you arm, and then when you arm it will go to the selected power.

[@JoshuaBardwell]

You can boot to pit mode now, but getting out of pit mode requires you to go into the menu. I am begging the BF devs to implement a Pit-Mode Flight Mode so you can switch pit mode on and off with an Aux channel.

[@kawsper]

Oh that is clever thinking to make it switchable with flight modes.

[@bohan9957]

I'm new to FPV, but have been flying R/C planes for 15 years. I'm a bit surprised to see all the video noise issues with the VTX these days. It seems to rival the old days when we fly on 72Mhz frequency, where servo glitching is a constant occurrence if you're not careful with receiver placement and not using motor capacitors. Why can't the VTX use some kind of frequency hopping technology like the 2.4Ghz radio system that we use to fly? I guess you'll first need to convert the analog video signal into digital and then send packets of data to the goggle. Just curious.

[@CgitEinsteins]

buset,,, om josua bawel keliatan lebih muda di video ini. berambut pula, haha

[@jamesgreenler8225]

Hello Josh from the future 😅 how do the controls work on a UAP ?

[@true911m]

Hi Joshua, In still pretty new and have been thinking about this topic. First, while dip switches are a pain, they allow you to change frequencies with the VTX powered down. The pushbutton options need to be powered up first, so if you're on an interfering channel you're going to do some damage. Adding a transmit switch is an option, but for now, what's the right way to deal with this? How do race organizers handle it? Thanks, man.

[@JoshuaBardwell]

Pit mode is the answer. Pit mode powers up the vTX at a very, very low output power, like < 1 mW, so you can only see the signal if nobody else is on it, and if you are within like 10 feet. You can also power up on an un-used frequency, at a super low transmit power, if you want additional protection.

[@rotovicious1156]

very informative thanks

[@kerjs02]

I am using TrueD 3.5 and have a question on frequency setting. If I use the search feature I assumed it would lock onto the correct frequency set on my TBS unify. I have been having a lot of trouble lately with my quad blacking out after flying for a while. Sometimes the video looks great on the ground but once I get 30 or 40 yards away the video drops where I just see black. So more info if you choose to help I have tried different cameras antenna flashing the trued 3.6 replacing the VTX. I have been finding changing the camera works best but I also found that the frequency is not matching the VTX. I would just use the find feature and let it lock on. I would think I should be matching the freq exactly for best performance. Can you expand on this a bit. The other things I have done is direct bat direct fc capacitor and all these things work to clear the video but my problem is total loss of video not quality. Areas I fly vary from open field to parking lot little to now objects to interfere with signal. The other thing is I can fly a few days with no problem at all then others I black out as soon as I take off. So is this something expected or should I expect the video to be more consistent until it is not ie broken parts.

[@DangerDavefpv]

i fly alone but im curious is there difference in vtx output power when on a certain channel? i most time have idk why i have them setup on 5740 but can i get better vtx power on different channel? like change my quad and goggles to 5645? weird question and im not sure if most vtx output more on certain channels

[@cJhudanich]

do you have a video on blackbox and failsafe, signal loss or rssi. had my first I gusse brownout with taranis and xsr from maybe 75 feet away.

[@imacracker515]

This video is the story of my life. Friends dont listen to this advice and I get knocked out of the sky. I understand forgetting, it happens, but it is really annoying when one doesn't want to head the warning like a 5 year old that doesn't want to listen. But flying alone isn't quite as fun.

[@JasperTielen]

Joshua, does LHCP and RHCP help when being close to each other?

[@BBFPV]

good question!

[@ArneGlodde]

in some German competitions we used this LHCP RHCP method to get a fair amount more separation in-between pilots, so I would say yes it works but if you are only using RaceBand its not necessary, if you want to get more dense (~12-16 pilots) it's a definite got to

[@BBFPV]

Komisch wir schaffen auf raceband nicht mehr als 4 Leute, liegt aber vielleicht auch daran das alle mit 600 mW senden und die nicht richtig trennen und kein CE. Ich geh auf LHCP und gut ist, soll 20 db bringen.

[@dooddrones6521]

As far as frequency bleed is concerned: Is there any sort of electronic filtering we can do, on the transmitter,to help minimize this? Would it be s matter if having antennas highly tuned for each specific frequency? Also, do you think a 2 piece carbon fiber shell that can quickly be put around a transmitter's antenna during power up could help fight this problem?

[@dooddrones6521]

Edit: (Hate typing on this phone) Would it be a matter of having antennas highly tuned for each specific frequency?

[@JoshuaBardwell]

+Abc Xyz no, it would be a matter of redesigning the RF circuit to use a different spectral mask.

[@dooddrones6521]

Gotcha. Too much added complexity for the size we're working with I guess.

[@Lawzy]

Josh, on a related matter, how real is interference between the quad based 5.8g VTX and the 2.4g RX (with diversity)? I’ve read a lot about the need for separation.

[@JoshuaBardwell]

Many people fly with little separation and no issue.

[@Mannedavid]

I can't use 25mW... there are just way to many WiFi networks around my "go to" fly spot.. sometimes I even get interferences on 600mW...

[@Mattwonga]

Using the tramp vtx and Bf f3 fc, i guess i have to use the white wire, but where should i solder it to get access to vtx setting from the osd?

[@JoshuaBardwell]

kzbin.info/www/bejne/sHfFZnyApbJkjrc

[@omatheusfortunato]

Hey Joshua, does 2g4 interfere in 5g8 fpv system? I've seem that using UHF 433/915MHz modules, the range of the fpv 5g8 @600mW increases very well. The same range is not reachable using stock 2g4 radio tx. What do you say?

[@JoshuaBardwell]

If you have a very high powered 2.4G system yeah it can interfere with 5.8G. Generally, though, no.

[@DarrelMartinez]

There a way to use the band scanner to analyze RF in the area i'm flying in? If so, can you do a overview on how to understand it? FPV please answer my call.

[@JoshuaBardwell]

Well yes, but it's of limited usefulness because it's a very simple band scanner. If there are peaks when your vTX is turned off, it's best to avoid those frequencies.

[@timan2039]

What are your thoughts on the efficacy of cleanswitchs on video transmitters?

[@JoshuaBardwell]

I haven't really tested it much, but it seems at a casual glance like it works.

[@VdubSPAZ]

[@JoshuaBardwell]

How do you propose to install the Faraday cage?

[@AngryPepper1964]

Joshua you mentioned that your favorite channel is 5740, could you please help me understand why?, and what the difference is between a good and not so good channel is. Thanks.

[@JoshuaBardwell]

It's completely arbitrary. I have since moved to r8 since it voids wifi interference.

[@AngryPepper1964]

Ok, thanks.

[@makinaliving]

HI! Anytime I increase the VTX to 1W, I have like blips / weird things with my drone, which are eliminated if I decrease the power to 500mW or less. Does anyone eventually had this kid of issue? Any tip? I've been fighting this for a very long time and can't seem to find the root cause...

[@makinaliving]

[@alphapapa77]

Any way to default the power out to the lowest setting? Using the Matek and Smart Audio.

[@JoshuaBardwell]

In BF 3.3 there will be a feature that automatically sets output power to 25 mW when you are disarmed.

[@BrockLeeFPV]

I know this isn't the right video but I'm having trouble with my lux v2 fc. My dsmx is bound to my dx18 but when I go into the receiver part of betaflight and move my controls nothing is responding. My motors fire up just fine and my gyro works too. I'm new to building quads I need help please

[@JoshuaBardwell]

In the Ports tab, enable "serial RX" for the UART that the receiver is wired to. Nothing else on that UART. Wire the receiver to the RX pad on the UART in question. In the Configuration tab, set the receiver type to "serial receiver" and then set the serial receiver provider to one of the Spektrum types, I think spektrum 2048 is probably right.

[@BrockLeeFPV]

I did all the those settings and still nothing. Does it make a difference by selecting the uart tab first then solder the dsmx or not. I can get some of the controls to show up but they move with the controller

[@BrockLeeFPV]

Also the receiver has power with the battery and USB

[@MrCineris]

Hey Joshua, can you make a video about the main reasons we get random failsafes? I've been getting those a lot indoors lately and no idea why...

[@JoshuaBardwell]

+MrCineris your receiver, antenna, or transmitter is probably damaged.

[@MrCineris]

Joshua Bardwell Even if outdoor it is all good?

[@JoshuaBardwell]

That's pretty weird. Indoor problems usually relate to multipath, but I don't think that should be an issue with 2.4 GHz control.

[@MrCineris]

Joshua Bardwell Is strong wifi signal capable of causing those? It's a large concrete building with a closed atrium in the center where I was trying to fly

[@JoshuaBardwell]

+MrCineris yes it's possible I suppose.

[@PowerScissor]

Is it possible for VTX's to "watermark" the image for each channel & then the RX rejects anything without that watermark, thereby eliminating ever getting a different channel than yours? I feel like processors are fast enough these days to do that with little latency.

[@rajgunaseelan44]

PowerScissor It is possible in digital transmission, not sure in analog.

[@PowerScissor]

I was thinking something like a QR Code that has built in error-correcting, and can stand up to a fair amount of missing data. And only needing to distinguish between 40 or so frequencies could be relatively simple.

[@JoshuaBardwell]

You're inventing spread-spectrum, which is a digital technology. Personally, I wish somebody would put some work into digital standard-definition for FPV. Digital HD for FPV is expensive and hard, but digital SD ought to be much easier. I wish we lived in a world where we could have 40 channels of digital SD that didn't interfere, and I think we could have it, if people weren't so focused on HD. Granted, HD is the future, and anybody who put the work into digital SD would be left behind in a few years, but I can wish.

[@ziggyzbeak]

Joshua I have a problem that I hope you will help me with, my wizard X220 got the receiver pulled out and two of the pins in the flight controller got pulled out. The pins are very small so I want to use the other side and I was wondering do I have to use a spectrum receiver if so can you give me a link for it. Can I use the same receiver ? Can I use my Flysky transmitter i6, I cant afford a taranis right now is there a setup that I can buy under 200$. Please help. CHEERS and thank you.

[@JoshuaBardwell]

+ziggyzbeak if the pins got pulled out then you probably have to replace the FC. At least if you're using those pins. If you have an i6 transmitter then you should be using the ia6b receiver.

[@ziggyzbeak]

Thank you for your reply I just ordered a taranis radio and the Frsky x4rsb reciever I think this will work Thanks again. CHEERS

[@gamerpaddy]

i recently got one of those quanum auto scan 5.8 receivers. when i power on my 25mW TX it finds it on Channel A4 or B5 or even C5. The TX is set to Band A, Channel 4 and its not the usual skyzone/boscam cheapbrick. those channels are all within a +-5mhz range.

[@racefacefpv7294]

If someone is running a LHCP and another person is runny RHCP on the same channel. What happens? I ask because I fly with a group of people where newer people will show up which is great but sometimes they just power up with out asking questions. Everyone runs right hand so I'm hoping left hand will keep me away from everyone.

[@JoshuaBardwell]

+RaceFace FPV it'll significantly reduce the interference but it will still interfere if you are close enough to them.

[@ephektz]

It's also maybe important to point out that 200mW isn't massively better than 25mW. With 25mW you are getting 13.98dBm while at 200mW you are fetching 23.01dBm. So you're getting around an S Unit and a half increase, which when taken in the real world isn't a huge amount of change. Also for reference, 800mW would be 29.03dBm.

[@elementaryfpv5666]

When I fly, I always fly QRP.

[@ephektz]

[@mistery79]

Is it true that you need a HAM license for 200mw and above?

[@josinaldoweb]

HAM license is not for frequency 5.8ghz

[@JoshuaBardwell]

+Josinaldo Barbosa yes it is. There is a 5 GHz ham band and those are the rules (part 97 I think) that FPV usually operates under.

[@JoshuaBardwell]

@mistery79 you do need a ham license to operate almost all FPV transmitters, but 200 mW is not the requirement. The rule can be summed up like this: if the transmitter is certified, then the operator does not have to be certified; if the transmitter is not certified, then the operator has to be certified. There are only a very few Part 15 certified vTX on the market, but if you are flying an "FCC Certified" vTX then you do not need to have a ham license. Since you are probably not flying an "FCC certified vTX", you probably are required to have a ham license to operate legally. FCC certified vTX do have output power restrictions. A vTX that transmits over a certain power cannot be FCC certified. This is why you hear people say that transmitters over a certain power require a ham license. But output power is NOT the only requirement of an FCC certified vTX, and it is false that all transmitters under a certain output power are legal to use without a license. (In the United States. Other countries are different.) It is also absolutely false that, as Josinaldo suggests, 5 GHz requires no licensing at all. 5 GHz is not a wide-open field, do as you like. There are rules and regulations that apply there. You are allowed to do things in 5 GHz ISM, U-NII, and ham bands, that you can't do elsewhere, but there are still rules.

Hey Josh, im having a problem with my fpv feed. When i power on my radio (2.4Ghz) it seems to interfere with my googles (white horizontal lines scan across the screen). Could i come down with the connections to my betaflight F3? Id appreciate any help.

[@JoshuaBardwell]

That's pretty weird. Are you using a 2.4 GHz video transmitter?

[@bwanabizz]

yes, Im using a TBS unify and a TGY-iA6C receiver. This interference increases if I increase the power of the unify.

[@JoshuaBardwell]

I don't think the issue has to do with your quad. Also, it's really backwards that the problem should get worse if the Unify power is increased. I think you should find that if you move your controller further away from your goggles, the problem goes away. If that's the case, then the problem is probably in your goggles or your video receiver.

[@bwanabizz]

The problem doesn't seem to improve, if I move the goggles away from the controller, that's why I'm assuming the problem originates from the drone.

However if you are all flying at low power, there is more tolerance for mistakes. 25 mW is very capable of flying in many environments. I definitely think people should start at 25 mW when they are new to a field or club, and only go higher if they are sure everyone knows how to do it safely.

Jesse Peacock yeah I do remember Steele saying that he keeps his unify on 800 without it burning out but if I'm on 200 and somebody else's on 600 it doesn't matter where he powered it up it's going to blast me out of the sky maybe I just need to keep mine on 800 then LOL

That's right, MOAR POWER! Get them before they can get you. A good defense is a good offense, right? As Joshua said, good practices are everything when running high power. Do it for the penetration, everyone loves penetration.
