Yes, virtually all commercial-grade two-way radios require the user to
be licensed. In the US there are a few VHF and UHF channels that don't
require one but these are low power. You probably have a similar
setup where you live, though it wouldn't be the same as in the US.
The HT1000 is a professional-grade radio and is used by police and
fire agencies in many locations. You might wish to investigate an
area where you can run your radios which is the field of amateur, or
ham, radio. The site to look up the general subject would be
http://www.ARRL.org. In the meantime I would suggest that you not try
to use your HT1000s because there's a fairly good chance that do
so would interfere with a licensed user and that would mean
big
trouble.
