I found this thread through a Google search, as I heard something a few times that I didn't know was possible.
Complete beginner here, so what do I know?
It sounded like a group of people having a conversation simultaneously on Channels 14 through 22.
I heard it this morning on the 5 through LA/Commerce. And last night on the 605 through Pico Rivera/Whittier/South El Monte.
I didn't check the lower channels, but they were on all the 50w channels.
Am I imagining things? Or have others heard that?
