I wonder if they really use a JRC 240 for surveillance or if that was just some stock footage.

The North Korean version of a one-time-pad (read message number 69 on page 823 of today's book, read message number 100 on page 957 of today's book") etc.

Considering how close these two countries are and the heavy use of radio and TV jamming by both sides...I'm surprised South Korea isn't just jamming the frequencies in question (or better yet, sending nonsensical messages to confuse the authenticity of the NK-based transmissions).  I'm going to go out on a limb here and say that North Korea, with its antique power grid, likely possesses considerable less potential (or actual) broadcast band transmitters, I'm talking mediumwave AM, shortwave AM and VHF FM broadcast bands in addition to VHF/UHF TV.  Since South Korea uses digital TV for over the air broadcasts on both VHF TV and UHF TV bands and North Korea uses PAL analog...jamming North Korean TV is probably not too difficult. North Korea apparently makes heavy use of the VHF TV frequencies to cover wider broadcast areas compared to the UHF bands.

I'll go one step further, and say these "secret message" broadcasts are pure disinformation - they're being sent to non-existant spies.

Why not? All we can do is speculate. However, it's interesting that these broadcasts, not heard for 15 or so years, start again just a couple of months before Kim Jong Nam was assassinated. It could be be pure coincidence, and more psy-ops than anything else. It could also be how they were told to go kill him. That's the mystery of numbers stations for you.

I've seen North Korean TV.  It's in the best interests of South Korea to let the world see it.  It's 100% propaganda straight out of Orwell's 1984.  The first time I saw it, I thought it was a parody or disinfo campaign.  :D
