What is the fine if you make an illegal short wave radio station on an already used frequency near where I want to start broadcasting on it without a broadcast license?
The exact fine for operating an illegal short wave radio station without a broadcast license will vary depending on the country you are in. In the US, you could face fines of up to $10,000 per day, as well as potential criminal penalties.
I'm in North Korea.
In that case. I cannot give you a definitive answer, but I can tell you some information that might be relevant.

First of all, it is illegal to operate a radio station in North Korea without a license from the government. The government tightly controls all media and broadcasting outlets, and only allows content that supports the ruling party and its leader.

Second, it is also illegal to tune into or publish frequencies of foreign broadcasts, such as those from South Korea, China, Japan or the US. The government routinely jams foreign radio signals and monitors the radio sets of its citizens.

Third, the penalties for violating these laws are very severe. Listening to foreign broadcasts is considered a crime against the state and can carry the death penalty or imprisonment in a concentration camp. Operating an illegal radio station could also be seen as an act of treason or espionage, and could result in harsh punishment or execution.

Therefore, I would strongly advise you not to attempt to make an illegal short wave radio station on an already used frequency near where you want to start broadcasting on it without a broadcast license in North Korea. It is very dangerous and risky, and you could face serious consequences if you are caught.
