Thanks guys.
@mdwa - The first draft of the video was without the music, but I had some music tracks that I liked laying around that I found in the youtube's music library and I thought that maybe I should finally use them in some video. And that's how they ended up in there. I'm glad someone liked them.
@Ice - Thanks for the tips. Regarding the radio, indeed I could contact the Kunsan tower but I made one mistake which I could have easily rectified if my DED was operational. I set the CNI switch on the AUX COMM panel to BACKUP, I've entered correct frequency for Kunsan tower (292.3), left MODE knob was set to MAIN, but I didn't set the right MODE knob to MNL - it was set to PRESET, so instead of broadcasting on manually selected frequency I was speaking to someone whose frequency I had set on currently selected channel. If the DED was working I would see that frequency but because it was dead I wasn't aware of what's going on. I realized all that on my next flight when I was trying to figure out what I did wrong before.
edit: Also for my defense I rarely have to deal with such situations as I'm usually either bring the bird back 100% operational or ride a silk elevator. So for me it's one of the two extremes most of the time
