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.
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
