Timewave's customers swear by their DSP filters and PK-232 owners love the flexibility and reliability of the most popular data controller ever built. The PK-232/DSP rolls it all into one! The PK-232/DSP brings a new level of performance to
the legendary PK-232 with sharp, accurate filters for all the data modes. Weak signals magically appear from the noise and QRM bounces off the new filters for cleaner copy with fewer errors than the old analog filters.
More Filters, Better Filters, Automatic selection The PK-232 was designed in 1985 before the advent of affordable DSP technology. The filters in today's analog TNC's were state-of-the art in 1985, but they pale beside the performance of DSP
filters. (We know a bit about RTTY/data filters - old and new. Timewave built a DSP Terminal Unit for the U.S. Navy in 1988, before most amateur radio companies could even spell DSP! Unfortunately, $3000 for a TU was a little high for the
average ham, so we put DSP on hold for the ham market until 1993.)

The PK-232/DSP brickwall filters have tighter bandwidth and steeper skirts for improved noise and QRM rejection. New PK-232 firmware (Ver. 7.2) allows a wider selection of filters than the original PK-232, so the filter can match the mode.
The correct DSP filter is automatically selected when you choose a new mode. In RTTY, Timewave's proven Twin Peak Filters pluck the mark and space tones from the noise and QRM for great copy. In PACTOR, the filter bandwidth
automatically changes when the baud rate shifts in response to the error rate of the link. In Morse (CW), the operator can preset either 100 Hz or 200 Hz bandwidth. The PK-232/DSP is completely compatible with all existing software
terminal programs for the PK--232.

The PK-232/DSP comes with a complete cable and connector set, in addition to Timewave's on-line and telephone support.

All the Proven Modes
The PK-232/DSP supports all the PK-232 modes - PACTOR, VHF/HF Packet, AMTOR/SITOR, Baudot, ASCII, Morse, HF Weather FAX, TDM, and NAVTEX.
