Example FEED 1: I have a Radio Shack Pro-2067 and a Uniden BC-796D, Digital and Trunking capable scanners on the system.
- The first, a Radio Shack Pro-2067 is connected to the RIGHT SPEAKER and is used to monitor Stamford's Trunking system. This scanner is connected to a
20 dB GaAs-FET Preamp then uses RG-11, 75 ohm cable to feed a, home-brew, 9 element beam which I made from a Radio Shack (15-2160) UHF-TV Corner Reflector antenna into a 860MHz duplexer cavity.
- The second scanner, a BC-796D, is connected to the LEFT SPEAKER with PL/DPL Decode and is used to monitor local conventional frequencies. PL/DPL Decode is needed to filter out other agencies using the same frequencies as well as to filter out the Morse Code Identifiers used on repeaters to transmit FCC call-signs. The antenna is fed by RG-6, 75 ohm cable to an all band, Discone antenna.
The Audio from each of these radios are fed to the "LINE-IN" jack of a Dell, Pentium II, 600MHz PC with 96MB of RAM.
For software, I am using SpacialAudio SimpleCast v2.3.7. The SimpleCast sends the (DUAL MONO) audio to ShoutCast DNAS server which is running on my Web/Audio Server located in Dulles, Virginia. The server Operating System is FreeBSD 4.7 Unix into a Gigabit internet backbone connection. From this we can support several hundred streaming audio connections at any one time!
The SimpleCAST software can be downloaded from SpacialAudio.com and DNAS ShoutCAST Server can be downloaded from ShoutCAST.com.
If you are interested in adding a scanner to this site I would be happy to help you set it up and host your scanner. Contact me.
