I’ve been struggling with this problem for a few weeks now; I have run out of ideas and turn to you for help.
APM 2.6 + external compass/gps running plane 2.78b
-RFD 900 Telemetry Radios on both sides, running SiK 1.9. 3 DB antennas on the receiving side (tablet/PC size) and stock antennas on the plane.
-1.3ghz for video (800mw)
-ezuhf for control
I’ve checked the noise levels with all my gear turned on, and I get 20-30 noise readings on local & remote (with about 90-110 value for RSSI)
I cannot fly further than 150 meters without losing telemetry. I’ve tried changing my AIR_SPEED to 24 from 64, but does not help. I’ve also tried powering the local radio by USB and external BEC, same results. I have no issues with video or EZUHF; I can go as far as 35 minutes affords me without losing either.
I am using two antennas on both RFD900 radios. I see some people are only using one? I haven’t tried single antenna.
Attached are pictures of the RSSI values, my configuration parameters & the plane layout. Any help, input or suggestions would be greatly appreciated.
