Before transmitting, monitor your selected op-
erating 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 fre-
quency.
