Its a well known fact that spreading a signal in frequency improves channel usage and assists weak signalling - go back to Shannon's eqn. Look at first GSM (which used frequency hopping to improve usage) then 3G with DSSS. Also all the WLAN modes use frequency spreading. Methinks you're behind the times thinking single carrier modulation. Amateurs should move with teh times, not be stuck in the 1960's Andy G4JNT www.g4jnt.com 2009/1/3 mal hamilton : > Tonight another episode of transmissions taking up about 1 khz of spectrum > in a 3 khz allocation. > I think the time has come to ask OFCOM for their opinion.
