[Hackrf-dev] Air relay ADS-B to BTLE via single HACKRF in realtime

Sat Jul 11 16:43:55 EDT 2015

Actually I gree with Xianjun that he is absolutely right by not
disseminating source code. Since Chinese law called 中华人民共和国无线电管理条例 (Radio
Regulations of People's Republic of China) sets forth very explicitly what
cannot be done and what are penalties for doing so.

In case someone has forgotten, China has still prohibited You Tube and
China policy does not permit private installation of satellite TV
receivers, and I could continue the list. Before knowing all pros and cons
its better to keep it on the low.

Therefore I think code shouldn't be necessarily given around. In the West
we are more ot less accustomed to misdemeanors or felonies. China is not
the case and law there is still respected up to the utmost level (I won't
continue on this subject more). So I think no one should be asking for the
code. Anyway, Radio Regulations of People's Republic of China, particularly
clauses 37, 69, 73:

Google translation is limp, though, just to get the overall idea.
