For anyone asking for RSSI for unknown receivers:
- open it
- try to locate chips like 7761 or 31136, 99% of the FM receivers (35/40/72MHz) use such chip
- some pictures of the two chips below:

http://www.rcgroups.com/forums/attac...hmentid=770766
- RSSI is on pin 7 of 7761, or pin 12 of 31136

If the above fails, first search rcg archive using "rssi <your receiver>"
If fails again, try Google
Finally, ask here, but always post pictures !

I tried google and searching the forums. No luck!

I guess I will just have to have a probe around and see if I can find it.

R118 is 7761 based, so pin 7.
Search here for 7761 to see others pictures, and how they connected the pin 7 to their OSD.

Spektrum RX's dont have an analog rssi output. Since there 2.4 and use wifi chips for their systems.

Well, maybe something like this on the ar500 might be possible.

Needs a data output then something to convert it into a readable form. I'd like to have that feature also on my 6200.

Does anyone have any experience with a Futaba R608FS? I've searched the forums but can't find any info regarding this rx. I don't have a picture but the only info on the chip I can see is FP9067, 0747MP009 and 170KY. It's a double deck design with another chip between the layers that is unreadable. Any help would be greatly appreciated.
