Basic Definition of Simulcast
- Simulcast indicates that two or more transmitter sites are simultaneously transmitting the same signals on the same frequencies at the same time. This can be on either a Project 25 digital trunked system or conventional system.
- Often times these can be GPS locked oscillators so the frequency reference is within a narrow tolerance.
- Most scanners suffer from Simulcast Distortion. Please visit the Radio Reference Wiki Article . This is a somewhat technical article that presents what simulcast distortion is and how in some rare cases the issue can be mitigated when using non-compliant scanners. It also concludes that the best solution currently for mainstream scanners are the two below Uniden models. We include a list of potential alternatives as well, as outlined below.
