One of the most popular amateur Digital Mobile Radio (DMR) nets is the Brandmeister network.

The Def Con Proxy Ham talk was abruptly canceled by its presenter. No one provided any clear reason for the cancellation. However, I believe there is a relatively simple explanation for why the talk was canceled.
