Timewave's Powerful DSP Technology
Improves the PK-232!
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 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 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.
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.
