To kill time on my commute, I take ham radio videos and convert them for my Blackberry. The software I use is Any Video Converter free version. I put on earphones and listen to the videos on my train rides in/out of the city.
The places I’m aware of for ham radio videos are the following, but I’d really be interested if there are other sites that have videos I could view.
K7AGE on YouTube or any YouTube video converted or direct on my Blackberry
There’s also videos to view at Ham Radio Tube but the site isn’t Blackberry friendly like YouTube though viewing on a computer is fine. You can download the original videos as a FLV (Flash Video) file on to your computer and then convert it using the above mentioned software
