Unable to decode E1P-U2

Today I again recorded the sound of E1P-U2 during the pass of 12:55 UTC. Decoding has failed again. The next time I will select USB and then try to follow the tracking tone of 1200Hz instead of 2200Hz when listening in LSB. Mike (DK3WN) was successful using MixW and the comm port bridge.
