N Basic transmit operation
Before transmitting, monitor your selected oper-
ating frequency to make sure transmitting won’t
cause interference to other stations on the same
frequency.
ating frequency to make sure transmitting won’t
cause interference to other stations on the same
frequency.
It’s good Amateur practice to listen first. On the
HF bands, even if nothing is heard, ask “is the
frequency in use” once or twice, before you begin
operating on that frequency.
