It's worth noting, you'll very probably be in violation of whatever
country you belong to's laws if you mess with those codes without the
proper license.

In the US, for example, even amateur radio operators otherwise allowed
to do way more than the general public aren't necessarily allowed to
transmit spread spectrum outside certain spreading codes.
