Guys I have updated post 2 with detailed information on how to configure the NavView window to effectively monitor the system's performance.
If you could please send screen shots of your data with this formatting, it would certainly help the community and give more feedback to everyone.
Once again here is what I got so far:
Micro 12 receiver on JR 10x. PPM mode. World (besides France).
Antennas at 90 degrees on the horizontal plan.
Left antenna on the pitch axis, right antenna on the roll axis ( as seen from the front )
And the data analysis for the flight:
Lowest RSSI 1 rx: -85,5 dBm
Lowest RSSI 2 rx: -84,5 dBm
Lowest frame rx1: 20
Lowest frame rx2: 21
Average RSSI rx values: -70 dBm
No failsafe
4 losses of feedback communication ( 136/168 events ) for a total of 7 seconds
Lowest RSSI 1 tx: -99,5 dBm
Lowest RSSI 2 tx: -92 dBm
Lowest frame tx1: 9
Lowest frame tx2: 9
Average RSSI tx values: -87 dBm
So the Tx side is clearly weaker than the rx side, which makes sense: the data coming back to the Tx is less important than the data uplinking to the Rx ( flight orders ).
I will next experiment on the range warning slider to adjust it so that the margin before warning is optimal ( probably 20% margin ).
I have already increased it to 50% with no warning going on.
I will increase it by 10 % every flight until I get a warning in normal operation, then reduce it by 20%...
