So I did the mod on my Corona RP8D1 to see RSSI on Cyclops OSD.Has anyone else done this with Cyclops yet?I cant find the info on what parameter should display so I dont know if I got it right.Here is info on mod.I just soldered 10k resister to junction on purple line.

Here is what my OSD looks like with mod.Strongest signal is 2.1 top left.Doesnt look right to me.My rc range is <300m before I lose throttle channel.Other channels still working.

So I answered my own question.RSSI displays 0.1-3.3V. My issue now is why am I losing throttle channel and why dont I have a strong 3.3V to start?I will check antenna wire when I get home...at work right now

Supposedly the problem with the RSSi mod on coronas is that it shares some circuitry with coronas built in failsafe device. It was not recommended to do this mod from the reading I saw, as it could cause premature FS problems. Is this possibly a problem you are having?

Hi Derek_S, I was actually having range issues before I did the mod so I did it to see what my RSSI was doing when throttle cuts out.The mod looks to have worked but my signal strength is not what it should be.
