Skyper1 / 2 pager pocsag messages

Did anyone had successfully decoded pocsag messages from skyper1 or skyper2 pagers with the the help of the pocsag pager app? The frequency is about 466 mHz.

When i use the spectrum analyzer app, i am missing some strong signal peaks within this range, which can be seen with any sdr or hackrf device. The internal antenna should detect this signals.

Thank you.
