RSSI, yes. You know the green LED? It blinks about 100 times a second if it gets a good signal. You need a buffer for it and you get the RSSI.


No clue about PPM sorry.

Thanks to both of you, just the answers I was looking for...

Ordered that RX today, and am going to modify my v8 RX for RSSI...

I'm going to try it first with out the opamp, just the RC circuit...

If it doesn't work, then I'll add the opamp...

Using the Cyclops Storm OSD....

Here's another view of the buffer. Works very well. .03V (Off) to 2.41V (on) range for me.
