SC Upgrades for all PK-232 models
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 built-in sound
card, rig control, computer isolation and total USB connectivity, the PK-232SC rolls it all into
one! The PK-232SC 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-232SC 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-232SC is compatible with all
Windows XP, Vista, and Windows 7 software terminal programs for the PK-232.
Sound Card Interface and Rig Control
For maximum flexibility, Sound Card / TNC switching is both software and panel switch controlled.
The sound card mode selection is software controlled. For example, when operating with Radio
Operating Center software, changing to PSK31 from Pactor or MT63 is a simple menu click.
The single USB cable from your PC also moves your logic level Kenwood RX/TX/RTS/CTS, Yaesu
CAT, and Icom CIV, RS-232 and USB Rig Control interface to the back panel of your PK-232SC.
