telecaster said:I have 53 flights with GoPro Hero3BE on my Phantom. ( Yes I keep a log of all my flights)
I have always turned the WiFi on the camera off, no issues so far.
Its really hard to figure out the reason for flyaways, wifi?, too much signal noise in the neighborhood?
The Phantom TX seems pretty weak, and the RX inside the Phantom is maybe an issue too?
Anyway in a week or two I will be replacing the TX/RX chain with a new Jeti DS-16 TX and a Jeti RX.
Even if the Phantom is more or less a toy for me, it would be nice to keep control :idea: :arrow:![]()
k8xd said:Having a substantial electronics background, and working on many different types of TX and RX over the years both commercially and as a hobbyist I have a bit of knowledge on this topic. For those that believe they have a problem, has anyone tried RF shielding and grounding for the receiver, repositioning antenna, and a few other basic radio techniques? (The Phantom has little if any RF shielding as is, and they position the antenna near the camera mount) Its rather hard to believe that with both devices operating in totally different bands segments there is a problem. Transmitter/receiver coupling, while even in close proximity with devices which is not close frequency is near impossible, but saturation may be. Additionally, these devices being digitally bound to common TX/RX combinations, not being in close frequency, on multiple harmonics makes it even more unlikely. Not having a GoPro3 I can not investigate with Station Monitor or Spectrum Analyzer. From specs on both TX in GoPro and RX/TX combo with NAZA, I see little possibility unless antenna or Phantom RX is being saturated with signal from camera, but again, the mismatch in frequency or harmonics makes it unlikely. In any case, repositioning the RX antenna an odd fraction of the wave length, and adding RF shielding and common ground for receiver would add an element of security.
If there are distributers that monitor this forum, has any one requested they contact NAZA-DJI or GoPro product development, engineering, or electronic service for assistance or determination. Just curious with the number of devices from both products out there and being used in tandem with even commercial operators all over the world using the Phantom and other DJI products/devices as well as GoPro why there hasn't been service bulletins coming from NAZA-DJI or GoPro if there was a problem.
While all these products are a FCC Type 15 product and must accept any and all electromagnetic interference in the 1.2 and 5.8 gig segment of the band just like garage door openers and other bluetooth devices. There are numerous techniques that can be employed to make interference rejection more substantial. The greatest we have available is the spread spectrum digitally bound technology and good basic electronics radio engineering techniques.
