thank you for this video. I'm new to the RM TX16s Tx family, so this is very valuable.
Glad it was helpful!
Very well explained From my own experience it is really necessary. With D8 protocol I lost signal at 150 m with one airplane. Never before with FrSky. So highly recommended.
Yes, if the option presents itself, you should do it.
What is d8?
@@ryanlemons3255 Hi receivers with telemetry "D" and 8 channels . Normaly they have allready A 1and A 2 analog inputs already in the receiver. Note that this tunning is necessary for any receiver,the problem it is in the module not in the receiver. The FrSky receivers a all tunned from factory.
I have a bunch of R168's and have been fine tuning them one by one, each 'mysteriously' ending up at -11. I had no idea that it only had to be done once per protocol. Also didn't know about not in low power mode. Many thanks.
You're very welcome. Glad to help.
With Edge tx v2.9.4 the fine tuning is automatic. You tell it to do it, about 30 seconds later, it's done. And if you think about it, programming this would be quite easy, just run it up and down, to exhaustion on each side, note the exit points, and then enter the median. We won't have to do this much more.
Not true. Fine tuning isn't an EdgeTX feature. It's part of the MPM code. If Fine Tuning appears with the protocol you select, you should perform it.
Awesome Very well explained Cheers 👍👍
Glad it was helpful!
as usual very well explained / demonstrated - Thanks now no worries about this subject ... climbing the mountain step by step, thanks to you
Glad it was helpful!
Thank you. Great vid.
Thank you.
Nice informational video. This makes it perfectly clear on tuning frequency. Keep up the good work John.
Thanks Bill--will do.
To the point - thanks
Thank you so much for making this video!
You're welcome.
Thanks for sharing.
Sure thing Jeff.
Me: How much did you frequency fine tuned your radio today.. ?!
RC Video Reviews: YES...
"Like tuning your TV back in the day" I am sure a good amount of your audience has no idea what that means, like rotary phones HAHA.
I bought one of the new Radiomaster SBUS receivers. I have a TX16 without the multi module, only ELRS. Is there anyway I can bind to the SBUS receiver or am I screwed?
You need ELRS receivers to bind with ELRS transmitters.
You could buy a Radiomaster External 4in1 module. That will bind with the RM non-ELRS receivers. PS It helps if you use model numbers i.e. R168.
Hi .
I try bind with futaba reciver .sfhss.
Servo eleron elevator throttle rudder function .but rssi just 0db.
How can I do
easy like a walk in the park😊😊
Worth performing too...
What is the range option next to the bind option?
Thanks for explaining! I've done the finetuning since the start. Every time I forget to set it, I get lots of 'Telemetry lost' warnings. So it's very important. But my question is, why finetuning has to be done only once. Can't the sweet spot differ between different receivers of the same protocol? I've a friend telling me that he did it with different RX of the HOTT protocol and hat difference in finetuning up to 50 points on the scale. This is much. Maybe we should do it with every single receiver?
1) The MPM developer probably knows more about RF than most, and here are the exact words from the manual: "Once the Fine Tuning value is known, it can be used for all models which use the same protocol."
2) Other TX's don't even have a fine tune option. The reason is because the manufacturers of TX and RX specify the frequencies to use--precisely, and they tune the TX/RX to those frequencies which is why the fine tune option didn't really exist until we had an MPM. So if stock TXs don't have a fine tune option, doesn't that imply the RX using a given protocol will always use the same frequency? I mean for a lot of years I've bound FrSky Xx, Dx, Sx, Lx receivers without ever adjusting the frequency on any radio--until the MPM.
3) Sounds like HOTT has a QA problem.
At the end of the day, it's your money, your hobby--do what you think is best. I'll trust the actual developer of the code who specifically wrote it's not necessary until my radio gives me a reason to believe something else.
Another great informative video. I didn't know about the fine tuning. I am having trouble binding, but as you requested this is not a bind question. My current module status is T-E-A-R. Is there a way to change it to A-E-T-R?
The MPM download page has options for channel order in the firmware.
Ever since I switched my tx16s from Opentx to Edgetx the Fine Tune option is missing for me. Any ideas on what could have happened?
Fine tune option is protocol dependent. If the protocol doesn't support it, it won't show on the radio. Select a known protocol like D16 and see if it pops up. It should.
@@RCVideoReviews I am using D8....shouldnt that support it? Im pretty sure it did before on Opentx on my tinyhawks and they dont use d16 right?
What if the negative side is higher than the positive side and your getting a negative number. Do I set the fine tune at negative 12?
Yes. Average them and use the sign.
i just bought e-flite turbo timber wich use spectrum protocol. Can i bind it to my muli protocol transmitter? and how ? Thanks in advance!
Use DSM Auto on the 4-in-1 MPM for protocol.
Hi. can u make a video on signal flooding? many RM receiver users are facing this issue.
could this be the reason I am haveing issues binding my FrSky Sr6 reciever?
If you set frequency fine tune to 0, you should be able to bind any rx. This is just a fine tune step to ensure the Tx and Rx are tuned as close as possible.
Does a specktrum or a lemon needs this tunning? What are tthe signs that your radio is not using correct tuning, los of signal and crash? thanks
If frequency fine tuning appears when you select a protocol, it's suggested to do it.
It's not quite as clear cut as "loss of signal and crash". It's more like listening to the radio in your car when you start getting farther away from the source--it kind of starts to fade and you hear interference, eventually you can't hear it at all. Better example is tuning in UHF channels on an OTA Analog TV. The closer you get to the center freq, the better the picture.
@@RCVideoReviews ok thanks i understand the example but since i crashed yesterday just after changing the settings for the telemetry so i stop listening that annoying warning. I thought the problem was that i lost reception because the plane started to turn to the left without any control until end up on a tree. locally it is a small apprentice Stoll 700m. no mayor damage but rider remained tunes to the left without any reason.
thanks for answering my questions!!!
Turn on logging and look at the RF telemetry. Take the guesswork out with data the radio can record.
Thanks for showing this. I’m using edgetx on my TX16S. My RSSI doesn’t change from zero but my rx will change to indicate signal loss. Is there a way to activate the RSSI?
If RSSI is sent from Rx to Tx it will be presented on the calibration screen. There is no need or option to add it. You can discover sensors on the telemetry screen to use RSSI elsewhere in your setup but the RSSI value shown in the fine tune section is sensor independent. i.e. It is displayed if it is sent/supported.
Is this including external 4-1 module? And how about Elrs? And how about those receivers like flysky receiver with no telemetry? Do we fine tune those? Ty so much love you're video.
Frequency fine tune is only conducted when the selected protocol offers it as an option on the screen. So bottom line, if you see Frequency Fine Tune as an option, conduct the process.
@@RCVideoReviews Ic so if there no option im good. But if there is option system want's me to do fine tuning. Why cant it do it automatically? By the way ty so much.
Ultimately, I believe that's where the developers would like to be--automatic fine tuning. Just not there yet.
Ahh SEND IT!!!!!!!
Weird how some models just drop from the sky sometimes eh? :)
I always wondered what this setting meant 🤣 I dabbled with it but gave up
Hopefully this cleared things up a little.
On my specktrum reciver I can not find it the fine tuning
If fine tuning isn't presented after you've selected the protocol, it's not supported by that receiver.
Does DSMX need to be fine tuned as well?
If the protocol does not show a fine tune option, it doesn't need to be done. If it does show a fine tune option, it does need to be done.
It has been said there are no dumb questions, but after I ask the following you may feel differently. Why did you devide by 2? Was it because of the 2 extremes of the frequency tune? How you arrived at 8 made sense, why you divided by 2 escaped me, but then leaded gas was still a thing when i was young so I may not have the capacity to understand
You are looking for the center of the range.
That's what the software developer prescribes: Calculate the median between the two values (TUNE_MIN + TUNE_MAX) / 2 = TUNE_MEDIAN
@@RCVideoReviews This shows the difference between the SW engineer and the mathematician - this is actually the mean - not the median. :-)
Question, I had a plane go down due to signal shadowing would doing the fine tuning help my frequency issues?
No. Fine tuning just more closely aligns the tx/rx transmit frequency. It wouldn't resolve legitimate obstruction issues.
I was told not to have the RX close too the TX when tuning as it effects the results.
And what do you see when you try it both ways?
I agree that having the RX too close affects the results - RSSI just doesn't appear stable at less than 3-4 feet. The same problem can occur when binding - being too close swamps the RX and the bind becomes a real struggle.
I just ran the same exact test at 1' and 10' and came up with the same value. So I'm not seeing it that way. But, your money, your hobby, do it whatever way suits you best.
@@RCVideoReviews I tend to put the rx in a different room so i can still see the bind light then tune it until the light goes out and the RSSI drops out ( + & -). You don't get a great deal of difference in the tuning numbers and like you say do what works for you.
PaulG is right in that you can get swamping if the Rx is too close. I usually fix that with a little space and by pointing the active element away from the Rx. If RSSI is unstable to start, then the tune won't be right.
Good Video. I have a question about the fine tune with Sfhhs protocolé. I just open my radio master tx16s MarkII elrs but could find the option for fine tune?? What i can do to get these option on my radio? Thanks
One problem:
If you have a Radiomaster ELRS you don't have SFHHS protocol.
I just looked on my MPM and with Futaba selected, RF Protocol SFHSS, Frequency Fine Tune is sitting right there where it's supposed to be.
@@RCVideoReviews i order the wrong radio. Just i order the multiprocolo module 4:1 thanks
partner I'm not able to do this configuration using an external module of ExpressLrs in my case it keeps giving warning of RX Lost and does not connect to the radio.
There is no frequency fine tune for ELRS as far as I know.
@@RCVideoReviews OK thank you
Great video. one question when i did mine i can up with -4.5. Do i set it to 5 or 4 since I can't do 1/2 input?
Thanks
It doesn’t matter that much. You’re .5 off either way.
@@RCVideoReviews Thank you
Is it still a good idea to tune a receiver if I have an XJT module and am not using the onboard Multi chip? Thanks
No. This is an MPM (Multi Protocol Module) process.
Is there no menu in EdgeTX?
Hi buddy. :) I have another question. So I ended up getting a og Tx16s. I did went to you're channel via discord. Under Jimster. But I'll copy and paste. Ty a lot. :) Hi guy's. I have a few issue. I have bought Tx16s original one 4-1. Anyway's. I calibrated the gimble couple time but channel four which is ailerons right stick I'm on mode 2. When I don't touch it. Channel monitor shows stick jumping 1539 to 1540. Even if i have trim center. And Left stick rudder. jump as well by one point. So is this normal because i know there issue on these first original tx16s. Another thing is Multi set on SLT because I am using Tactic slt receiver. It showes rf freq problem is this isn't a telemetry that detect rssi. How I rf tune it? Oh and sometime it looses settings that i have to go add multi and slt. Odd behavior. i paid 85 for it and came with two tactic receiver. But disapointed these issue which I have no issue with mk2.
One of the developers on Edge responded to your gimbal question on discord. Regarding RF tuning: czcams.com/video/08W8usnP0dA/video.html
@@RCVideoReviews Ty but there no RSSI on none telemetry receiver right? Because my receiver only receive command from transmitter. Tactic TR625 according to product page and pdf it isn't receiver that send information back to radio. I'm so confuse :(
Do you need to rebind after fine tuning? Thanks
I would
dear i have TURNIGY 9x8c v2 , 8 ch full range receiver and also hobbyking , HK- TR 6A V2 , 6 CH , digital receiver system , pls can i use them with radio master t 16 ? and how i can use them , which protcol ? and if these work , so can i also need to fine tune FERQUENCY . pls guide , because i have more then 14 receiver of these
If you look on the product link at Hobbyking, the protocol is specified in the description:
hobbyking.com/en_us/turnigy-9x-2-4ghz-8ch-receiver-v2.html
Protocol: AFHDS
Then look at the MPM protocol page here: github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/Protocols_Details.md
And you can see it supports AFHDS2A.
I'm not sure if AFHDS2A is backward compatible with AFHDS, so the only thing to do is try. It is a FlySky protocol on the MPM.
Ali ti ti sprejemniki sedaj delajo, na katero ime ste jih nastavil, številko ?
Hi please help me I'm facing an issue with tx 16s it's says low rssi after 50 meters idk why I'm a beginner and buy a new radio so don't even know that much please help me in this problem.
You need to bring this question to discord. Far too many things need to be unpacked to get to the bottom of this. I can't offer the help you need on CZcams.
@@RCVideoReviews okay bro give me the discord link and btw thanks for answering :)
Hello, how is this done in the Edge TX?
The radio in this video was/is running EdgeTX.
Radiolink as well you have to fine tune
Simply put, if frequency fine tune appears when a protocol is selected, you're advised to perform the tune.
Didn't know to divide by 2 , was in the formula.
Yup--you're looking for the median value: Calculate the median between the two values (TUNE_MIN + TUNE_MAX) / 2 = TUNE_MEDIAN
