I remember Ray-W4BCX reported the same issue with the V2 version, of the random false signals, and the clip light coming on at times as well.
With the V3 update, this no longer happens for him.

Re the Clip/Error LED there is a user manual here: https://github.com/drowe67/codec2/blob/master/stm32/doc/sm1000_manual.md "Connection to your Radio" (8) has some guidelines for the level that will answer your question. I'll run a few tests here and get back to you! BTW Peter VK3RV is often talking to Jose LU5DKI about 1030 UTC 7.177 +/- QRM each 9South Australian) evening - you might be able to monitor Peter direct on your SM1000 if you're in the shack.
