PK-232/PSK
Timewave
Multimode Data Controller
Timewave’s Sound Card Interface
Improves the PK-232/DSP!
Timewave’s customers swear by their DSP filters and PK232 owners love the flexibility and reliability of the most
popular data controller ever built. Now with the addition of
a sound card interface, the 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.
More Filters, Better Filters, Automatic selection
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.
Software controlled and mode independent
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

All the Proven Modes + All the Sound Card Modes
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.
