SOTA - Summits On The Air is a subsection of the
Ham Radio hobby.
It promotes
Amateur Radio Operation from the summits of hills and
mountains.
Radio hams who transmit from the summits are called
Activators.
And radio amateurs who contact the activators are known as
Chasers.
People who do not have a transmitting licence but enjoy listening
to
amateur radio transmissions are called
Short Wave Listeners - SWLs.
They may also take part in
SOTA by keeping a log of all the contacts
they hear between activators and chasers.
