S17c calling "777" plus X06

S17c changed their frequencies as a part of its seasonal changes. Usually 5301 kHz is noisy and weak in my QTH. Lately I dial my tuner on S17c try to see what surprise the mechanical YL have for us. Today she called "777" along with a X06 transmission which was stronger. Here it is a sound sample, 5301 USB 1250z. The message was "62027" (as usual a "0" is in the middle).
