Technical InformationThis radio scanner is located near the Rohnerville Airport in Fortuna, at approximately 200 feet of elevation. Meridian Hill is directly to the east but the locale provides line of sight to all of Fortuna and most of the Eel River delta. It has excellent reception of all North Coast mountaintop repeaters. The antenna is a vertical VHF collinear, about ten feet long, mounted at the top of a short mast. The scanner monitors about 70 local channels at 20 channels per second. The analog audio is fed into a computer sound card input. The computer processes the audio and converts it to the various requested formats. The digitized bits are then wrapped into packets which are served up using a SHOUTcast server. Each listener gets an individual 24 kbps (kilobit per second) stream. Overhead and switching adds a bit more. 300 kbps of upstream bandwidth allows the server to send up to ten streams at once. The processing adds a 30-second delay. By hustling to your computer after the fire siren sounds, you will still be able to hear the original dispatch! |
