Evaluate the security posture of legacy alphanumeric paging systems still in use today.
POCSAG (Post Office Code Standardisation Advisory Group)
Wide-band FM demodulation on known paging frequencies (typically 138-174 MHz or 450-470 MHz).
Pipe raw audio into a POCSAG decoder to translate Frequency Shift Keying (FSK) bursts into ASCII text.
Alphanumeric paging uses Frequency Shift Keying (FSK) to transmit data. This simulation captures a 1200 baud burst on 152.000 MHz and translates the raw audio tones into ASCII text via the PDW engine.

TUNE SDR TO 152.000 MHz
Most paging traffic remains unencrypted and unauthenticated, often broadcasting sensitive operational or personal data in the clear over a wide radius.
In many regions, receiving these signals is legal, but disseminating or acting upon the contents of private messages is a violation of privacy laws.
