# FMTools # FMTools
FMTools is a repository of apps you can use to make your FM broadcast better, pirate or not this will help you if you don't have something, maybe you want a better stereo encoder? SCA? or even went crazy and decided to do quadrophonic? We have what you need, for RDS just use MiniRDS FMTools is a repository of apps you can use to make your FM broadcast better, pirate or not this will help you if you don't have something, maybe you want a better stereo encoder?

In the 1950-1960s the FCC had to decide between two stereo coding systems, we had the Zenith/GE system and the Crosby system, what was the diffrence? In the 1950-1960s the FCC had to decide between two stereo coding systems, we had the Zenith/GE system and the Crosby system, what was the diffrence?
The Zenith system had a 19 khz pilot and a 38 khz dsb-sc modulated stereo l-r signal, sounds familliar? yeah that's why you haven't heard of the crosby system The Zenith system had a 19 khz pilot and a 38 khz dsb-sc modulated stereo l-r signal, sounds familliar? yeah that's why you haven't heard of the crosby system
The crosby system on the other hand had a (better) decision of modulation the l-4 signal into 50 khz with FM, why was it rejected? becuase of SCA, 67 and 41 khz were used up by stereo, 41 khz was also used up on the Zenith system but who cares The crosby system on the other hand had a (better) decision of modulation the l-r signal into 50 khz with FM, why was it rejected? becuase of SCA, 67 and 41 khz were used up by stereo, 41 khz was also used up on the Zenith system but who cares
Also it doesnsn't sound bad, how may ask where did i find a decoder for it? Made it myself in GNU radio, it's even easier, if they chose 35 khz instead of 50, then we'd be using this, also i like this one because it has FM, not AM so if some idiot has a transmitter with hardware pre-emphasis then the stereo won't be affected by it Also it doesnsn't sound bad, how may ask where did i find a decoder for it?
