Hello, I'm discussing with a friend about the FT8 maximum power allowed in Canada (see below Industry Canada extract) .
Is FT8 a transmission of an audio 8-FSK signal that is then used to modulated the amplitude of a carrier (USB) or a "pure" 8-FSK rf signal? I suppose the later since documentation described a constant amplitude signal which then prescribed 750 W PEP max. Am I right? 73, Fred VE2WFB ----------------------------------------------------------------------- Industry Canada RBR-4 - Standards for the Operation of Radio Stations in the Amateur Radio Service 10. Restrictions on Capacity and Power Output The transmitting power of an amplifier installed at an amateur station shall not be capable of exceeding by more than 3 dB the transmitting power limits described in this section. 10.1 Amateur Radio Operator Certificate with Basic Qualification The holder of an Amateur Radio Operator Certificate with Basic Qualification is limited to a maximum transmitting power of: (a) where expressed as direct-current input power, 250 W to the anode or collector circuit of the transmitter stage that supplies radio frequency energy to the antenna; or (b) where expressed as radio frequency output power measured across an impedance-matched load, (i) 560 W peak envelope power for transmitters that produce any type of single sideband emission, or (ii) 190 W carrier power for transmitters that produce any other type of emission. 10.2 Amateur Radio Operator Certificate with Advanced Qualification The holder of an Amateur Radio Operator Certificate with Advanced Qualification is limited to a maximum transmitting power of: (a) where expressed as direct-current input power, 1,000 W to the anode or collector circuit of the transmitter stage that supplies radio frequency energy to the antenna; or (b) where expressed as radio frequency output power measured across an impedance-matched load, (i) 2,250 W peak envelope power for transmitters that produce any type of single sideband emission, or (ii) 750 W carrier power for transmitters that produce any other type of emission.
