.......... I placed the RID behind the gimbal, in front of the rear status light, there are no electronics there but all the wiring goes thru there. It has its own lipo battery so its not connected to anything. Im not sure if it had anything to do with it. I just dont know.
My RID module is mounted the same as you describe yours. I did a couple of checks. I see a little difference in the signal, but not much.
Here is how I set it up:
1. For a good comparison, ensure both drone and controller are in the same place, and facing the same direction for each "flight".
2.) There is no actual flight. This is done on the ground, motors off, no camera. I haven't done other variations.
3.) Remove props.
4.) Pick a location to place the drone. Probably distance is better than walls, but each has advantages. I did one pair of checks with the Drone/controller close but separated by a heavy wall. The second pair of checks was done with about 100 ft distance between drone and camera. Either way worked, but "distance" is easier to document as a variable.
5.) Turn on
Module, Drone and Controller.
6.) When GPS acquires, start motors in idle for a couple seconds (to initiate a new Flight Log), then turn motors off.
7.) Let is sit undisturbed about 15 or 20 minutes.
8.) Shut everything down.
9.) Turn the RID Module off.
10.) Restart
only Drone and Controller. Start motors again for a couple seconds. Let it sit undisturbed another 15 or 20 minutes.
11.) Shut everything down.
12.) Download your flight logs and compare the rsk_fssi column of each record. Ignore the first and last minutes when you were moving around the drone/controller. Or any period when anything else may have been moving around either of them. You can also upload the Flightlogs again and we can produce images to compare your results.
If the same problems exist both with and without the RID Module, it gives more reason to look harder at some of the other issues that could have produced the same gaps in your original logs.
