    Noise is being picked up at the ceramic antenna, not the wires.

      That is my opinion. Everyone is addressing the wires. Which I did because it doesn't hurt or take much time to do so. I did wait until I had a secondary reason to open it. I guess one could put a bit of a shield around the GPS on some of the sides. I have not seen that addressed. I just think it is located in the wrong place on these quads. Love to find a better mount/mounting location. Won't be a BIG problem on the 7-inch because I just plan on using it for LR flights. It should never be upside down for any reason. However, I really would love to freestyle the 5-inch. It will work perfectly for that. But I also want to fly it for autonomous flight beyond simple RTL. And I sure do want RTL to work 100%. That seems to be a hard task on these small frames without a mast. I do think I have the 7-inch fixed well enough. Testing and flights will tell. But the 5-inch really has me worried for anything except a Betaflight freestyle drone without a GPS.
      I also think the quality of the GPS module has a lot to do with all of this. Filtering circuits and such. I have been trying to buy a decent GPS module because I can't change them much.
      IMHO because Betaflight has just gotten their rescue mode working, more and more of the smaller frames will be trying to use a GPS and hopefully some new tech will come from that. I as I stated in my video and as you stated, I think the majority of the problem is in the module, not the wires. Because everything is so mashed together on these, I think induced noise into the wires is a problem. It may be a 10th of the problem that the module itself is, but I can address it fairly easily.
      And it gives me something to do with my time. 😊

      @@nighthawkvs Its not the antenna that has to be shielded, the things that need to be shielded are sources of noise. Power wires, Gopro or action cameras, fpv cameras, esc.

      @@cdog3257 Those two battery wires running through that area is also a thing I hated during the build. Was thinking of doing the 5-inch differently.

    vern youre even better at making up new handles for me than I am ;-) fyi I got the copper shielded wire and its really just too much to fit into the small channel I am using.. may go with tape...

      I am so sorry about that. Very embarrassed by that mistake.
      It was pretty easy to apply the tape. Not sure it will do much, but I feel one must try. Hopefully several small fixes will make a bigger overall difference.

      @@nighthawkvs No worries about the handle it just makes me chuckle...In all candor my handle of choice is A-Bit. As in "a single bit of data" That was not allowed by googles algorithm so this is what I came up with... If I remember from my machine coding days a byte of bits could be upto 40 characters.... which leaves me with the question... Does this handle make me look fat? ;-)
      It would be interesting to apply an O'scope to the rx and tx lines ... now that I think about it a ferrite core might do the job nicely... I will continue to look into this.
