I received the following blog post as a submission.
Apparently there is a DMR war going on between several users of the VE3TWR Toronto Repeater. There have been spoofed radio ID’s and even jamming the repeater till the point that they were forced to change to C4FM (P25 Phase 1) mode to stop the jamming. Both YouTube videos are at the link below.

EDIT: We removed the youtube embeds as the post on the blog has had its youtube audio updated.
