Yup, it transmitting at 152.840 and the paging idea makes sense. It's still transmitting loud and clear today at noon. It also seems busier. Also my loacation is: CM97as if that helps.

edit: Also, it seems that the paging Modes have "noisy" data encased between beeps. At the moment, POCSAG 512 baud looks the most promising.

edit again: i got an application that decodes POCSAG and it works intermittently. I have recieved some interesting text. The morse also came again and said: WPVQ32E22
