I have a Roku streaming video box at home and was browsing some of the channels the other day and came across Ham Nation on the Twit TV channel. It's a weekly web show hosted by Bob Heil with Gordon West and others. They demo new equipment & modes, how-to technical advice, & promote the hobby. It's a well done show and here's a link to watch:
