Station Summary

DP01 is a unique station that uses both polytones and a digital mode, which is how it gets the name Digital Pseudo-Polytone. It was first heard in April of 2008.  The digital mode used is a QPSK modem with two channels at the baud rate of 62.5 bd. There is a possibility that DP01 is not an actual numbers station though, and it is rarely heard.
