I still enter them in mine. If I know there is a very slim chance of the TG not using encryption, I may avoid it. If it's a TG I don't hear very often or can't personally verify they use encryption 100% of the time, I leave it on. It's easy enough to temporary avoid if the TG starts holding my scanner up on a regular basis. The database is not always accurate on who is 100% E and who is not.
Good points. Digital Trunking is NOT like scanning frequencies. The most commonly used receivers for P25 Trunking are quite capable of ignoring ENC. As a result, including them in a favorites list has practically zero impact on the efficiency of the monitoring.

Correct. In fact, I don't believe any program will decode (not decrypt) encrypted audio. If a program does, it's usually a result of a bug, and sounds like a robot having a stroke.

Some programs used to decode them and play the scrambled audio, but since have been updated not to.

I use SDRTrunk, this will decode the encrypted channel and log, but not playback any audio. (There's a GitHub branch for ignoring ENC)
I don't think Unitrunker tunes to ENC.
DSDPlus has options to ignore ENC, but doesn't do it by default.
My SDS100 ignores encrypted, but sometimes it will briefly tune to it and immediately start scanning again, so quick that I barely see it show up on screen. But a reboot fixes that.
