[Spooks] Odd voice under RNZ National on 15720 KHZ

[Bruce Atchison]

Hi folks;

This isn't exactly a numbers station question but I hear a 
strange-sounding voice under RNZ National on 15720 KHZ at 04:00 UT. It 
seems to be repeating the same thing over and over. As best as I could 
tell with my Kenwood TS-440S, it seems to be on 15722 KHZ USB. I tried 
but I can't pick out what it's saying.

Does anybody know what this station is that's underneath the broadcast 
station?

Sincerely yours,
