From time to time I may broadcast various activities around the station. For example, operation during a contest, tower work, etc.
About the broadcast: Video is provided by a Logitech QuickCam Pro 9000. When receiver audio is broacast, this is a hard wired connection from the transceiver to a sound card. Audio from the main receiver on the left channel and sub-receiver on the right channel. The advantages are no extraneous background noise is broadcast, viewers hear what I hear whether I am using one receiver or both, and I can use headphones without disrupting the broadcast audio streams. The disadvantage is this leaves me with no easy way to broadcast transmit audio. Until I come up with a solution for this, there will be no audio while I am transmitting. The broadcast is encoded and streamed to Justin.TV using Adobe Flash Media Live Encoder. For general purpose audio (broadcasts containing audio not from the station receiver) various microphones may be used.
Out of the box, many QuickCam Pro 9000's have focus problems. They will focus up close, but not at a distance. Mine would focus only to about one foot from the lens! After reading this page and this one, I took the camera apart and adjusted the lens. After turning the lens approximately three quarters of a turn clockwise, the camera will now focus from a couple of inches to at least 25 feet. I have not yet tested it beyond that range but I believe it should be OK to infinity. I was able to turn the lens using my fingernails, but it was not easy.
