A $1.29 FPV diversity controller (improvements)

Part 3 of this series shows how the uber-cheap FPV diversity controller system performs better with the addition of two extra components...
1 x 820K or 1M ohm resistor between pins 3 and 1 of the LM324
1 x 0.1mfd capacitor from pin 3 of the LM324 to ground
1 x 0.1mfd capacitor from pin 2 of the LM324 to ground
With this modification, the diversity controller switches more cleanly and isn't tricked into switching prematurely by very short-term changes in the RSSI levels.
