Thought Provoking
Hello all,
TWF provoked me to giving some thought to this and on the few occaisions I have strayed from the 'Ham Bands' to listen on the Av band, I have heard transmitters definitely 'off freq' and wondered why. Now I know! Ashamed to admit as an Avionic Tech that I hadn't heard of this system before.
I wonder why this carrier offset technology is being persued however. Surely one would not hear hetrodyning if all of the transmitters' carriers were synchronised using a standard such as MSF or GPS? In much the same way as 7.5 Khz is outside the receivers' audio passband, so would close on zero beat be.
