Spanish speaking in real time, a series of phonetics followed by "preparacion", another series of characters and the anouncement "segundo grupo" and continues in this manner. The only reference I found is from a Twitter account claiming it is the Venezuelan Navy. I couldn't find anything on Priyom, as I thought it was a numbers/military/government station. Overheard on an IC7300, W6LVP loop from Richardson, TX.
