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. Now with the addition of a sound card interface, the Timewave PK-232/PSK rolls it all into one! The PK-232/PSK brings a new level of performance to the legendary PK-232 with sharp, accurate DSP filters for all its internal data modes and dual transformer isolation for sound card data modes. Weak signals magically appear from the noise and QRM bounces off the new DSP filters for cleaner copy with fewer errors than the old analog filters.
The PK-232/PSK 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 an internal 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/PSK is compatible with all existing software terminal programs for the PK-232.
The sound card mode is software controlled. For example, when operating with PK-TERM’99, changing to PSK31 from Pactor is a simple menu click. To run programs like PSK31, SSTV, MT63, Hellschreiber and MFSK16, as well as new, yet-to-be invented modes, just run Timewave’s ModeSwitch® program or enter a few short keyboard commands prior to executing the sound card application.
The PK-232/PSK supports all the new sound card modes in addition to all of the existing PK-232 modes - Pactor, VHF/HF Packet, AMTOR/SITOR, Baudot, ASCII, Morse, HF Weather FAX, TDM, and NAVTEX. The PK-232/PSK comes with a complete cable and connector set, in addition to Timewave’s on-line and telephone support. The PK-232/PSK has all the same mailbox (MBX) facilities as the earlier PK-232/MBX. Power requirement: 12 to 16 VDC @ 590 mA (700 mA recommended).
