why is my RSSI working without anything then?

for the last week the voltage range of 1.5 to 3 volts have clearly indicated signal strength. did i just get lucky? after calibration, my osd shows near 0% RSSI when transmitter is in microwave and 100% when next to the receiver. If i stand in between the two is dips to somewhere to 70-80%.

Good question, not sure how it works ! - maybe it is lowpass filtered a lot before it gets to the OSD?, maybe it samples fast enough and does max/min holding?

i connected my 9x rx to the cyclopes osd unit and i get 1.7 when in best signal and 0.8 when rc link tx is turned off.

i guess it correspondence to what others had come out with.

thank you for the info

Why not adding a LM358 to create a Voltage Follower / Buffer? Don't forget that when you connect the RSSI you take power that can false the data.
