Hi, this could either be an issue with the Frsky sending an occasional unexpected pulse due to temperature, or an issue with the OSD receiving one due to temperature. I don't believe we've received any reports of the latter, but I certainly don't want to rule it out (or suggest there's an issue with the Frsky, which also seems unlikely).

Yes, as long as the Frsky supports failsafes, you can just set the "no PCM pulse detection" to "yes" and as long as RTH still works when you trigger it, and you don't see any anomolies in your RC link, it should be ok.
