My Edge 3d plane has a single band R9 900mhz rx, that I use with a frsky tandem tx. It has a 3S lipo. Measurements were taken at 0.5 sec intervals, and with frsky logging the RSSI is a percentage.
At 207 sec the valid frame rate fell to 64%, one measurement only, with a level below 70 considered an incident. The RSSI remained above 70%. I looked for any anomaly in the power supply. With frsky logging you can simultaneously monitor 3 lipo cells. At 207 sec there is nothing happening, the rx voltage remains at 5.0v for the entire flight, and the lipo cells are all together, in the expected range.
I conclude there is no problem here, the R9 rx has been without a glitch for many months, and others have found R9 rxs, either ACCST or ACCESS, work great at PRCAC.
I want to log the rx voltage on my planes with elrs rxs, but so far I can only monitor either the lipo voltage, or the rx voltage, but not both. I use the lipo voltage for deciding when to land, and am reluctant to give it up. So I need to find a way to monitor lipo and rx voltage simultaneously, and I do not want to add a flight controller to achieve this.
