    If you are having trouble getting the 1000mw and 1200mw options unlocked, be sure you are running the latest firmware (v01.00.01.00) and if you are not in the US, you need to have the 700mw option in your menu. If you only have 25mw as an option, you will need to do the "FCC hack" first.

    Another great video Dan! As usual, your thorough approach provided lots of data and I agree with your conclusions. This test appears to be great for 700mw, so more power doesn't improve any metric. As you said, potentially long distance would be a good test. I wouldn't want to try that unless you had a GPS and a proven RTM capability. Thanks for the video!

    When we put the file on the sd card and put it in the goggles, do we need to keep the sd card in the goggles with the file on every time we want the 1200mw mode or does it write the file to the goggles firmware and then we can remove the sd card?

    What antennas are you using? I have noticed dramatic difference between stock and aftermarket antennas on the DJI system. Could stock antennas be a bottleneck as far as seeing a difference in range with higher power settings? I also wonder if the system is variable? Kinda like cross fire? Maybe aftermarket antennas would in essence open up the system to reach full power? Just a thought. - thanks for your help on Bardwell’s live streams!

      I have heard others that saw a bigger improvement. But they were either testing maximum range or were using better antennas.

    I tested it too and the air unit stays at less than 25 degrees after flight too and so, it don't become hot like before at 700mW. It seems clear that 1200mW is the max Power but during flight the air unit reduces power under 700mW maybe to avoid damage the air unit in time. No temperature = no hight power. The good news is that we can place the air unit where we want into the frame, no need air flow to cool it.

      Have you tried connecting the DJI system to a different UART on your flight controller? I don't think it can be connected to an inverted sbus pad if I remember correctly. Double check which UART you are using and make sure it is set up for your radio. Make sure betaflight is set up to use sbus. Try toggling the sbus fast option in the DJI goggles. Is there a wiring diagram out there for your flight controller that shows the suggested way to connect it to a DJI system?

  • @checkeredflagfilms
    @checkeredflagfilms 5 років тому

    Do a test behind solid building obstructions. perhaps it's not so much the 'range' but more the 'penetrating' power that makes the difference. if that's true, then you could make a case that it's not particularly good for the health of the pilot.

    • @5zero7RC
      @5zero7RC  5 років тому

      I was hoping the additional "penetrating power" would help with the image quality when going behind a tree at a distance, but I really didn't see a noticeable improvement.
      The additional power is a non issue as far as the operators health is concerned.

    Forget about how many milliWatts it is, RF is best measured in dBm. 700mW to 1200mW is not even a 3dB increase. That would equate to roughly 1s point on a signal strength meter. To improve range and signal quality it’s best to improve on the antenna. Higher gain antennas; improved signal capture area....

  • @rcrdps8144
    @rcrdps8144 5 років тому

    I don't have a HAM license either, but I'm pretty sure it doesn't let you bend the rules. It just makes it legal for you to use stuff that isn't FCC licensed, but still follows regs.
    But on the note of DJI's 1000mw,... or 1200mw, and the legality... I recently re-read the FCC testing for the 700mw. As far as I can tell, 700mw is not the actual output power. The actual power is more like 160mw per antenna connector. The FCC testing shows ~22dbm. Then you add the 2.84dbi antennas, and you're at 24.84dbm, which is 305mw. Then you double that because it's MIMO and transmitting on two antennas at once. So that's gets you close to what they claim is 700mw, or 25dbm total. So with a 7db patch antenna, you'd still be within regs( 30dbm), though you would now need a HAM license because it is no longer a certified setup. I don't think the FPV community even knows how to spell HAM, so I'm not real concerned there. But using the 700mw as an example, the 1000mw setting is likely not outputting 1000mw at the connector, and is probably completely legal with stock antennas,...which btw, are just dipoles on the goggles. Only the air unit is LHCP. Assuming the math above is correct, at the 1000mw setting, an upgrade to the antennas needs to stay under 2.84dbi. So how is it an upgrade? Well, with the stock antennas being linear polarization, and your air unit on circular polarization, you are losing 3dbm, which is half of your power. So upgrading to a good set of antennas with a high axial ratio, but still under 2.84dbi, should net you a huge signal improvement while adhering to regs. I assume this is why TrueRC labels their antennas as a 50% improvement.
    But knowing how DJI is doing their math, that means the 1200mw is not legal. Of course neither are the regular 1 and 1.2w analog VTX's unless your pigtail is really lossy. The FCC regs allow 1watt, and 6dbi antennas, but you have to stay under 30dbm total(1watt), so that means your cabling would have to lose 6db to run that 6db antenna.
    Sorry for how long that was. Just been enjoying the research,... Feel free to correct me,...with data of course. :D

      @5zero7 I think this one's second to last paragraph is what you were referring to on JB's video that did not contain that area. So I guess I'm wrong on that particular interpretation of the regs. Seems the rest of the internet agrees with you on the 36db total allowed. :D And using the DJI math, and the 36db with antennas,... the 1200w may very well be legal.

      @@thierry01500 Not sure of what you're asking or what your objective is. If the goggle is outputting 22dbm, add your antenna gain to that, then run it through a conversion to mw like this site: www.rapidtables.com/convert/power/dBm_to_mW.html
      Then, in theory you would double it because it's MIMO,....except you're running two different sets of antennas, and you have no clue which two it decided to talk on and in which direction. In my opinion, your best bet with this system is to use all of the same antennas pointed in the same general direction. You then select the type of antenna for how wide your flying area is.

    • @5zero7RC
      @5zero7RC  5 років тому

      sbus baud fast is for the DJI radio control link and allows it to be 7ms. The 25-28ms you see in the goggles osd is for the video link.
      The channel you are using can have a small impact on range, especially if you are using a channel that has other interference on it. Also some antennas are better tuned to specific frequencies so you might see a slight improvement using a channel that is as close to that tuned frequency as possible. However that does not usually make a significant difference.
