RSSI output to OSD
Each data received by receiver is confirmed by LED green blinking.
Regular, often blinking means good signal. Rare blinking = bad signal
The RC Filter converts the blinking into analog signal. RC filter output range is between 0V – 0,227 V as a max
signal. Such level is too low to be accepted by OSD. That’s why must be changed by operational amplifier from
0,1V to 2,71V
