Hey guys.

I'm new-ish to the RC world, and also a beginning electronics hobbyist. I'm better at the latter than the former right now, but I need a little help with both.

I'm working on an electronics project, and I really need to have access to some kind of signal strength indication from the receiver on an aircraft. I need to feed that data into a microcontroller.

I have seen a few scattered mentionings on the internet of a few old 72MHz JR receivers whose internal electronics had in them a pin which output an "RSSI (relative signal strength indicator)" indication. Obviously not made available to the normal purchaser of the product, you had to crack open the receiver to get at that pin I'm sure, but that's fine. It seems to have output a voltage corresponding to signal level... probably from 0 to 5V or something like that.

What I really need to know is, does anyone know what models had that? Or, even better, does anyone know any new (available now) receivers that have that in them? Especially 2.4GHz ones perhaps?

My electronics project needs to know when signal has been lost. An RSSI output would be great for that, but also if anyone has any ideas as to some signal that might be gleaned electronically from a receiver, to let the microcontroller know when signal has been lost, that'd be great too.

Thanks!

just search RCG and you'll come up with lots of hits, here's a thread on futaba receivers, both 72MHz and 2.4GHz: http://www.rcgroups.com/forums/showthread.php?t=923419
