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:

https://www.rcgroups.com/forums/atta...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.

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.
