ARLA/CLUSTER: Public Frequencies.

[João Costa > CT1FBF]

São os chamados canais FRS chineses ou Banda do Cidadão Chinesa.
China

A personal radio service similar to the American-style FRS in Hong Kong
<https://en.wikipedia.org/wiki/Hong_Kong>, Macau
<https://en.wikipedia.org/wiki/Macau>, and China
<https://en.wikipedia.org/wiki/China> is also approved by respective
organizations for legal "license-free" operation, with the name of "Public
Radio Service". However, different UHF
<https://en.wikipedia.org/wiki/Ultra_high_frequency> frequencies with 20
allocated channels near 409 MHz are used. Sometimes this is also being
referred as "Citizen Band" or CB in China,[8]
<https://en.wikipedia.org/wiki/Personal_radio_service#cite_note-8> but not
to be confused with the Citizens Band radio
<https://en.wikipedia.org/wiki/Citizens_Band_radio> within the 27 MHz band.
European, American, and Canadian residents are advised not to use FRS or
PMR446 radios for communication when traveling to the aforementioned areas.

There is big number of FRS band radios, being used in China "illegally",
started before the Chinese government opened the 409 MHz band to public.
Legal action against such usage is rare, because of the low power and short
range of FRS radios.
