Agree w/ everything you said MDK2, also have to add, these two announcers have AFAIK been the same for many years (decades?)... it's amazing they have anyone speaking English at all, so we have to give these two announcers credit for at least the "college try". Can't imagine there are a ton of anglos around to practice with. Also, you are correct the YL is far easier to copy than the OM.
As for style points mentioned by tRMZ, VOK has long been in a class of its own -- even since the 80's when stations like R. Albania gave them serious run for their money. For sure, anyone who listens to this station for a while will know the DPRK nat. anthem very well, which is what they play after the interval signal, and which gives the listener a relatively useless bit of knowledge that is interesting nonetheless.
Very interesting listening to this station in 2018 and reading between the lines (when you can make out what they say at all!)...
