Improving the signal on the R9M/R9M-lite and R9MM RX combo

I really appreciate your hard work testing and documenting. I can't justify the cost of Crossfire yet for my own use but I have snapped up an R9 starter kit.

[@marcind4795]

Thank you for tests. From my experience: 1. Be sure that your antenna module and antenna on receiver are the same frequency (EU or non-EU) 2. Stock antenna on module are weak - replace on super 8 3. Receiver's antenna in horizontal position On flex and 25mW (without telemetry) I got 4.1km without any problem (Tranis X9D + R9 + R9MM non-EU). Have FC+GPS , so lost of signal triggers return to home , theretofore I do not use telemetry in RX.

I think you are going to get the best range out of it on a wing. Stick your antenna way down the wing vertically polarized and get a half decent TX antenna and you are good. I'll have a play with flex though and let you know what I think

I know crossfire is the king of the game, but the R9M was 30quid i would much rather stick with the R9M and have to work the firmware game, than pay over the odds for a system i don't think i would use to its true potential.

[@CurryKitten]

I think lots of people have done the same and given it a go... because it's only £30, and the receivers are cheap and it's not too much more for a decent antenna. It's something you'll have to stick with a little bit until the bugs are ironed out, but it's certainly got some potential

[@jfree1074]

I appreciate your opinion sir and welcome it. Thank you.

[@chrisnoren777]

Now the R9m module comes with the super 8 antenna and the r9mm receiver comes with the T antenna. I use this set up. The module can ramp up to 1W. But that setting uses a lot of battery power and gets slightly hot.

[@CurryKitten]

Because FrSky left R9 out to stagnate, the best thing I can suggest you consider is flash both the module and the receivers with ExpressLRS - which is being actively developed at a very fast rate

Yes - of course we didn't know the stock antenna was crap until we tried a decent one.

[@CurryKitten]

Well, as per usual, it all depends. But I would always recommend a Crossfire over R9, it's just so better supported and TBS actually tell people what they are up to with it. You could go DJI, but you could do that at any point in the future, it doesn't stop you running Crossfire (or anything else)

[@valiant360420]

Thank you for this video!👍🏽

[@Grey390]

Hey CK, I think the RSSI values you are seeing in the OSD are not what your receiver is actually getting due to RSSI-scaling in Betaflight and/or your TX mixer weights. When doing these tests, you should also have a camera showing the RSSI value on your transmitter and you'll see a large discrepancy depending on how Betaflight is interpreting the RSSI input. The link between the TX and RX is scaled properly but betaflight most likely isnt and it changes whether you use F.port, S.port, Aux Channel, or using the RSSI ADC connector on the FC. Thats why you see a big difference when using the Aux Channel method compared to the rest in your video. Use S.port or F.port for the most accurate link between FC and RX then fly out and check the RSSI value on the OSD against the TX value and use the [set RSSI_SCALE = xxx] command in the CLI to tune it. This is true for all radio systems, even Crossfire where people might (incorrectly) be getting 99 db ALL the time.

If you want low level flights at a distance then TBS recommend their Diamond antenna over the stock one you were using. Try the stock Frsky antennas on a CF TX.

[@CurryKitten]

Hi Sean. The QX7 is a 2.4Ghz radio, so in order to use the R9 receivers (which works at 915/868Mhz) you'll always need to use the module in the back of the QX7

The FrSky T style Antenna's make a big difference too. But that along with the Super 8 Radio Antenna & the Nightly Build Firmware seems to be the winner. Having said all that, We did a few flights along side the TBS shod quads and the TBS STILL went further with a stronger RSSI on a low power setting. But I do think the the FrSky stuff is worth having and can only improve. Now there are so many units out there, I can't see FrSky being out done by TBS. On another note, isn't it about time you got some fixed wing stuff? I love your reviews, but I've got bored of the multirotor stuff now. Need an even balance of fixed wing and multi's.

[@CurryKitten]

Well, the T antennas finally came back in stock, so I have a few on order along with a Super-8 to test out. I love flying fixed wing, the reasons you don't see so much from me is that it's often a case of needing better weather or more room - and I don't tend to get offered my fixed wing stuff to review. That said, I've cleared my schedule a bit so hoping to do some more. I might put that 2nd r9mm I have in a wing and add iNav to mess around with

[@dj_dazzy]

RF side of CF and R9 are using very similar LORA modules, this shows the importance of tuned antennae and correct mounting. The wideband R9 whip antenna and monopole wire on the R9MM are only fit for the bin as they aren't tuned to either 868 or 915Mhz giving poor gain at both frequencies. Tuned Super 8 and T antennae are the way to go. I am still not convinced spliting the radiating elements of the antenna with RF conductive carbon is going to give the best results.

If you are on FCC I believe you only get the choice of 100mw. However, OpenTX 2.2.3 is now out, so this along with the flex firmware should give you some power options (I think - I've not tried it myself as yet)

[@flimunki114]

Hi Wayne, I'm surprized and sorry to hear you had such negative feedback to your original review, I anticipated similar signal strength from the R9 to the crossfire but other than that I have no misconceptions and can't argue that crossfire is a better system for various reasons. I've bought the R9 as a stop gap, I'm currently part way through installing it on a wing and 3 possibly 4 quads at less than half the price it would have cost for crossfire but will at some point be moving to the more superior TBS system. So far I'm finding it to be the usual Frsky fiddly firmware updates etc and a bit of messing around getting it working but no different to the Frsky 2.4 system. I anticipated the stock antenna for the module would not be great so ordered the super 8 antenna from the off and I'm due to test the Frsky 'T' antenna and TBS 'T' antenna on the receivers shortly so I'll let you know how I get on. It's not just about signal strength but from your tests it would seem that the Frsky system is more sensitive to antenna placement (I seem to remember Tom Smith running his crossfire antenna in 'V' configuration without too much detriment to signal strength) and as expected the stock antenna are not a patch on the TBS antenna. Great initial review and follow up.

[@CurryKitten]

It's more about people feeling a bit precious about what they've bought and then only seeing the good. I like to cast a critical eye over everything because nothing's perfect. I just saw the T antennas come back in stock, so I've gone and ordered a couple along with a Super-8 to test as well. I wasn't expecting such a dramatic improvement when using the crossfire antenna, so I'm hoping for great things with the Super-8/T antenna combo

[@bkmahaffey]

Forgive the newbee question, but what is the setup/connections differnce between channel 16 and telemetry?

[@CurryKitten]

On ch16 there's a signal that can be picked up directly by the flight controller and show on your OSD. The telemetry RSSI signal is sent from the RX to your radio, so if you want to show it on your OSD then you need to send it back to the RX as a regular RC channel which can then be interpreted as RSSI by the flight controller. A sort of round trip situation, so the setup is a bit more complicated

What do you have your RSSI audible warnings set to on your Taranis for the R9M? I thought that it was supposed to give audible warnings automatically and that you don't have to set them up using the logical switches and special function. But if not, and you have to do it manually, what are the thresholds you use when flying? 50% low and 45% critical? For mine, I've gone down to 45% and there was no audible alert.

[@CurryKitten]

I've left on default, so it's something like 45 & 42 I think. It does give an audible warning should the RSSI fall that low, but only if you are using the telemetry version, of course. It's one of the ways I figured out that there must be a difference in what ch16 RSSI was telling me vs the telemetry signal as I was getting single figure RSSI with no audible warnings (that's because the telemetry signal was still 50+). Did you discover the sensors ok to make sure your RSSI signal is there, and are you using the telemetry version of RSSI and not ch16?

[@strawhatsam]

@@CurryKitten So I did more range testing (drone indoors me running around town with a Tx like a mad man) and I found I finally did get the low alarm at ~40 and the critical at ~35. I was just using my Taranis for rssi reference so I believe that's the native telemetry rssi? When I was flying my quad for real though I set up my sbus rssi (R9 mini) through channel 12 (aux 8) and it did seem to align with the rssi on my Taranis, but I didn't push it far because I didn't want to dump my drone.

[@dinantdekruijff4735]

Hello Curry yes the problems with the R9 units are the Antenna's not the modules the Transmitter stock Antenna is way of its centerfrequentie and also the reciever does it have (bad antenna) I personally messured these antennas and they have a SWR of 1.4 which should be at least 1.2 because of the bad tuning you get these dips. I have modded the stock antennas by tuning them and I have now a SWR of 1.1 or less the Antenna's of Crossfire are better tuned so they work a lot better. When you have mismatch between the send/reciever unit and they antennas a lot of the power gets feedback in the R9 modules which gives a bad rssi. I can confirm that by change to a better tuned antenna the Frsky modules are exactly as powerful as the Crossfire system. So buy the Crossfire antennas and take a tuned dipool for flying around and not the special ones like Moxon because they have more gain and be very derectional and let be sure a drone at 1km from you could be everywhere so a directional antenna can cause more problems then better reception. Love your channel and keep up your way of bringing info. People needs to listen good so they know what you say. Greetings from the Netherlands with kind regards Dinant de Kruijff aka DroneMadnessRC

[@CurryKitten]

Interesting stuff - really handy when someone brings me some solid info like this about the SWR. So do the TX and RX antennas just have the problem of being the wrong length, or does the tune involve something else ?

[@FredoCorleone]

I have one quad which doesn't lose signal, not even 500m away doing rolls of any kind, and I have another quad which loses signal 50m away while doing rolls... One is fiber glass the other is carbon fiber... Do you think that could be the problem? Both quad are very similar after all.

What I have in this video was the first version of the antenna which is 900 on the basis it will work pretty well on both... and it does. If you are pushing the extremes of you limits then that's when a tuned 868 antenna will help more, but it's not a dramatic change, and if you are flying quads you may not notice the difference.

Hi Curry K. What about the TBS Crossfire Micro Module? Would you go with the Crossfire module or the R9M? I'm looking at a reliable RC link for long range fixed wing FPV, but willing to pay a little more for something that just works. Any thoughts?

[@CurryKitten]

I did a review of the Crossfire micro, you can find it here kzbin.info/www/bejne/e2m5hpewhtVjZtU The Crossfire is a better system quite simply - it works reliably out of the box, is better documented, and has far better software integration with OpenTX. I looked at it mostly in terms of flying a quad (as it has some really noticeable latency improvements) so whilst it'll work long range, I don't know quite how far the 250mw max on the micro module will give you, and depends what your definition of "long range" is. I think it would take you to at least 10km though

[@olivierhacking]

Very informative video, thank you. I have a Turnigy 9X with opentx so I am doubting between getting the R9 module for that or getting the new X-Lite controller with its R9 counterpart. And secondly, would you say the Frsky T-antenna is close to the TBS Crossfire T-antenna tested here? Thank you very much for your contribution to our hobby!

[@CurryKitten]

Are you talking about the new Xlite Pro... as that seems to need a bit more development before I would consider it at the moment... the fact right now that it only speaks ACCESS protocol and the original R9lite module won't work for it... should be fixable, but not yet. Yes on the antenna front though, in the range I was testing, which I would call "typical quad" flying, so out between 300-500m but down low there was no discernible difference between the TBS and FrSky antenna.

[@olivierhacking]

@@CurryKitten Good to know those antennas perform similarly. I was actually referring to the normal X-Lite. Is it worth switching to it now that I want to make the move to the R9 system, or is the R9 module in my upgraded 9X radio a better performer? Maybe it is impossible for you to answer...

[@CurryKitten]

There actually a difference in the modules. The R9M-Lite can only go up to 100mw, but the full-sized R9M that will fit in the 9X will go all the way up to 1W. Depends what you are flying and how far away you want to go.

Nice testing Wayne, the results were what I would have expected really, slight RSSI on telemetry vs channel 16, but by all means nothing out of the ordinary, I would say that channel 16 is perfectly acceptable to use, all be it a bit more jumpy. I wonder if that's more a sample rate or refresh time than anything else. So the conclusion is, rather predictably, FRSky dipoles are complete crap lol, but once you pull the heatshrink off and see how they soldered them up they are poorly built. TBS antennas and R9 module the clear winner. Also for your next test a Super 8 and True-Mox is the next logical testing step.

Just by adding a TBS Crossfire antenna it made the R9 system better. Can you do a video using crossfire micro tx flying that same field?

Ive found the best results on the Flex firmwares, i noticed they seem to be working only on the flex firmware and that may just become the only firmware for this system. I didn't use the beta open tx but updated the receiver and module for the xlite and the only thing is not having the option for 100mw with telemetry which is what the beta open tx allows. Thanks for this info!!!

So if you keep your radio on 2.2.2 and update to flex, presumably it just stays on 25mw with telelmetry (for the x-lite at least ?) I've got a Super-8 on order now, so I'll be having a compare to that stock TBS antenna - hopefully it'll come out at least as good and hopefull better !

I do - although depends a bit on what you want to do with it. But there's not much in the hobby you can get for that cheap, and all you need for the receivers to be at least as good as the 2.4Ghz equivalents and you've got potentially cheaper receivers !

[@pergius]

I am looking around the market for a new controller and I've found the QX7S with the r9 module included for the same price as without it.. guess it means that I can't justify to go TBS Crossfire when looking at the costs.. see if I'll regret that or not. :S

[@CurryKitten]

If you are getting free stuff, it would be silly to turn it down. Let's hope for some decent updates soon. I've been holding off doing more videos on the R9 as I'm waiting for the over the air updates FrSky mentioned to me a few months ago

[@pergius]

@@CurryKitten Yes, exactly my thought. And oh, nice to hear about the over the air update. In my opinion the strongest selling point for TBS.. Just hope that the wait isn't too long. Thank you for the heads up! :)

[@TidewaterAerialSolutions]

Do you have to update firmware when you get it to make it wirk

[@CurryKitten]

I didn't do a firmware update on this one, it was just a case of messing with the way I read the RSSI and trying different antennas. Since the time I filmed this, there has been new firmware that says it fixes some issues with the RSSI measurement (although it's a bit vague about what it fixes exactly) so it's probably worth updating to the latest.

[@TakeItToTheGround]

Your last review must have cursed me - reverse reviewers curse? Been flying using FCC and having rock solid rssi, 99% almost always. Watched your last review and suddenly I have failsafes left right & centre, No firmware changes, no hardware chnages, no nothing. Anyway just ordered an Frsky Super 8 Antenna from horusrc. Fingers crossed or it's TBS next (may need to save my pennies).

[@CurryKitten]

Haha, it's the first time I've managed to pass on bad vibes through the power of the Internet :) I've got a Super-8 coming now, so I can do a direct comparison to the basic TBS one - hopefully it'll do well

[@TakeItToTheGround]

@@CurryKitten Thinking about it the only thing I have changed is going from Inav 1.9.1 to 2.0.0. However it was suggested I upgrade to 2.0.0 as it has "improved" reliability for sbus and R9 in particular. ☺

[@arendmookhoek4314]

thats amazing, seems to me its just as good as crossfire just slightly more hassle to setup and you need your own antennas. HOWEVER THIS COSTS 25 DOLLARS FOR TX AND RX SO YEAH!

[@CurryKitten]

Yep - It's all good if you don't mind some more hassle and don't need that latency improvement that CRSF gives you. If the receivers stay that price it's cheaper than 2.4

[@arendmookhoek4314]

@@CurryKitten jup, I can definently not afford crossfire or a taranis, so I'm modding my flysky to work with r9m right now. The latency is unfortunate but can't be helped. For most mini quad stuff I'll use my 2.4 flysky anyways, and believe it or not that actually has even better latency than crossfire.

[@MrStevegibb]

Seems like the qx7 with the full size r9 module is the better option for long range flying.

Yes - you've more options for power settings, and the module seems to get a better signal even on the same power output ?!

[@hillbillyfpv1]

Great reviews.. enjoyed the content and yes, I watched it all.. lol!!

[@kenneths7984]

Your reseults seems to correspond with my own findings. The stock TX antenna is truly awful. I went with a Moxon antenna from TrueRC and it made a huge difference. Thanks for doing the tests. Looking forward to your test of the Super 8 antenna. Might want one of those as the Moxon is directional (but very good) Btw: I have one quad for more longer range which has the antenna vertical to reduce the risk of antenna nulls. For "close combat" I have the antennas horizontal as the antennas is better protected.

[@simong.8187]

Good video. Can you send me a link to the T-antenna you used?

[@CurryKitten]

Sure, it's the stock antenna that comes with the TBS Crossfire here www.team-blacksheep.com/products/prod:xf_stocktx_antv2 although if you watch the follow up video, I also test this against the Super-* antenna from FrSky which comes out about the same, and you don't need an SMA->RP-SMA adapter to use it

[@simong.8187]

Thanks a lot, that helps. Figured it was the tbs antenna but would have forgot about the adapter.

[@jeniferdiamond7723]

Wait what? I thought these low mghz Tx Rxs where supposed to give you "miles" of signal, this looks about the same as a basic 2.5 ghz

[@CurryKitten]

It will - but the circumstances have to be right. Not having crappy antennas is a useful one to fix, and an RSSI signal that's accurate is another handy one. That said, even with not great equipment, the signal holds up better in dodgy areas on 2.4

[@jeniferdiamond7723]

@@CurryKitten There have been 2 incidents where I lost signal at close range and it was from a 4 in 1 module for a T16. I still use the older D8 RX like the D8 2 plus and the smaller version " ripped the sticker off of it years ago so can't see its name" I had a line of sight disorientation issue with that smaller one back in 2016 it had to have got at least a half mile from me, it was tiny in the sky. I stayed calm and was able to turn it around. I have never flown that far away since. But I am wanting to try long range FPV, and now I'm not so sure.

[@CurryKitten]

Well long range isn't something you just "do" at once. It should be a carefully considered and slow progress - where you take into account where you are going to go, what's the recovery like if you went down, and would it be safe. Then you start to see what your equipment is capable of and if it goes well you try and push through that limit little by little. Sometimes you'll reach the limits of what is possible in your config and then you might have to reconfigure, or rearrange or replace - and then you go back several steps and start building up again. It can be a long process, but I always enjoyed finding the limitations and seeing what things I could do to mitigate the limits. The most important thing to remember is that nothing when dealing with longer range is simply plug and play and nothing is ever transformed to a long-range machine with just a single change

[@thirtythreeeyes8624]

You'd get another improvement if you mounted the antenna vertical, you want the feed line running next to the ground element of the antenna for the best radiation pattern with the active element inline with the feed line. Also putting it with the center feed point on carbon is a terrible idea it is massively detuning the antenna at best and at worst it will fry the rx if it's sending telemetry because of the carbon reflecting the power back into the antenna. With a decent set up on 25mw 900mhz you can literally go miles with 1w you could get 40-50 miles. It's all about good antenna's and good mounting of the antenna's. I'd suggest putting the antenna in a tube coming vertical off the front of the quad to try and get it away from the vtx antenna a little, you'd probably easily double the range with that alone. Great testing though I love any antenna testing video's.

[@CurryKitten]

Yes - there's a balance here between optimum setup for range vs what is "the norm" as far as mini quads go. As it stands, the practice of mounting horizontally polarised under a leg works on a mini quad as it's simple, you get decent range out of it, and it stands up to a lot of abuse. Sure, if I wanted to max the range or was flying fixed wing, then I'd be mounting vertically way away from other components. I've not heard of the idea of carbon reflecting the power back into the antenna. Obviously, we're not making contact between any antenna elements and the carbon, and the active elements are away from the arm - so I'm confused by the ability to reflect power here?

[@thirtythreeeyes8624]

​@@CurryKitten I should've said that the carbon will alter the antenna's swr causing more power to be radiated back down the co-ax, sorry I can see how that could be confusing an extreme way to think of it is putting a metal tube around the antenna, that will fry anything transmitting signal pretty quick. With the amount of power these are dealing with I wouldn't expect being up against a little carbon to alter it enough to fry anything that's why I said worst case like say you mounted length wise on the arm but, it's certainty not good for the rf link or the components transmitting telemetry. The way I like to mount my antenna's is with an rc car antenna tube the thicker the better just heat shrink it to the stand off and a drop of ca to keep it from sliding, much better than zip ties less flex more protection for the wire inside and and if you crack the tube they pull right off and are about $1 a piece at the LHS if those still exist in most parts of the world haha.

[@flighttherapybullisticfpv133]

Just remember the super 8 is a Moxon antenna so it will directional and you will failsafe very close behind yourself with a TRuRC 915 MOX or a Super 8 or the TBS Diamond

[@CurryKitten]

Is it though? Where are you getting your info. My info suggested this was omni, and seems to be backed up by the radiation patterns you'll find by doing a search on it... example: cdna1.zoeysite.com/Adzpo594RQGDpLcjBynL1z/cache=expiry:31536000/resize=fit:max,width:1200//compress/s3.amazonaws.com/zcom-media/sites/a0i0L00000QyvG7QAJ/media/catalog/product/s/u/super8_rad_pat_.jpg

[@flighttherapybullisticfpv133]

I am 90% sure yes.. personal experiments show that pointing the front edge toward your flying area it performs as a moxon should. I.E. it has good coverage in front of oneself but will drop off as soon as you fly to far behind the antenna. The only failsafes ive had on the system were from flying behind the antenna. Also when contscting TrueRc i was told that the super 8 was a directional antenna with a moxon-like shape modeled after the success of the TBS Diamond... whatever the truth may be I can tell you 100% that thr antenna is directional

[@MrJarrod]

Seems that frsky antenna quality is pretty cheap and nasty. Best use the tbs antennas like I do. But I use the tbs tuned antenna. With the immortal t on the quad.

Like to see all these antennas on an antenna analyzer. Great testing, bummer its not just working great to begin with. :) Kinda hard to come by, these analyzers aren't common even among Hams as there's not alot of folks that play in those freqs. though there may be someone on here that has one and has the adapters that could take a look at the vswr on these antennas. Lot of times these antennas are off frequency or poorly constructed and that may have a negative impact also.

[@CurryKitten]

Yes - it would be quite useful. There's not many people with the sort of kit that could test them... mainly antenna developers :)

[@RockTouching]

You could try a Moxon antenna if you want 99 rssi forever. I could send you one to test if you want when I receive my rg402 order :P

[@CurryKitten]

Yep - there's a Tru-Mox antenna that's tuned to 868. It's something I might like if I want to really push the range (probably more on a plane) but I've got a Super-8 on it's way now, so be useful to see if that holds up well

[@RockTouching]

@@CurryKitten The super 8 is a folded dipole design, it should help if you fly near the ground (like the diamond antenna does). But the ultimate range should be equal to the crossfire dipole.

I do not understand the various reviews described the frsky r9m hardware same as crossfire means theoretically should have a similar range :-)

Not so much about range for me, but FrSky is certainly missing some of the very lovely features that Crossfire has. More dev on firmware needed !

[@arendmookhoek4314]

The hardware is practically the same, but that doesn't mean they are similar! Tbs has put a lot of time into software and testing stuff, so naturally it will work better but you have to pay for it, it all works out in the end.

those antenna's arent good for horizontal orientation, if you turn that 90deg antenna it's flat against the radio and isn't that creating a small noise floor since it's hard up against metal etc. you're better of with the whip and just fly out to your side
