You're pretty much correct. The benefit of the record out jack is that you have an audio output at a constant volume regardless of what you have the volume set at on the actual scanner. So, for instance, you could recording something overnight without disturbing yourself while you sleep.Speaking of this Record Out port on the back of the BCT15, is it really any different than just using the headphone jack?
Also, how would it be if someone decided to use the External Speaker port? Though I believe that mutes the scanner.
EDIT: I just realized something as I was writing this post. Is the main reason to do this, because it will not mute the scanner, so you can hear it as normal but also record? Something you can't do, with the headphone port.
May I ask, where you got your cable?Thank you. You are absolutely correct on the page numbers. That explains why I was only recording on one channel from the sound card. I will try a stereo patch cord instead of the mono one I was using, and hope to get both channels to record.
