The following interesting interview, partially quoted here, can be found on N6PSE’s blog.
Ultimately, I was QRV from the city of Rajin from a telecoms center, with a mobile utility container next to a huge telecoms tower as my base. North Korean telecoms people hoisted my dipoles. There are many fond memories associated with that visit, including a party at the home of the mayor of the city of Rajin after the casino people had painted his house as a matter of kindness. Happy occasions to remember!
