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. The PK-232/PSK daughter board brings a new
level of performance to the legendary PK-232 with transformer
isolation on both audio input and audio output connections to your
sound card. The PTT and audio I/O connections to your radio use your
existing AFSK cable set. The PK-232/PSK upgrade will add all of the
new sound card modes to your operating agenda, not just PSK31!
PK-232, The Standard in TNC design
The PK-232 was designed in 1985 before the advent of affordable DSP
technology. The filters in today’s analog TNCs 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.) After the success of the DSP filter upgrade
for the PK-232, Timewave has added the interface needed for the next
generation of radio data communications - sound card based operating
modes.
Sound Card Transformer Isolation - In and
Out
Timewave’s engineers examined the new sound card applications and
added the necessary sound card isolation and PTT control to keep
your PK-232 current with the newest operating advances. This upgrade
allows you to explore all of the new sound card applications as they
become available.
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 ModemSwitch® program or enter a few short keyboard
commands prior to executing the sound card application. (Most good
programs will integrate the new commands into a single mouse click
as quickly as possible.)
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.
Easy Installation
Installation in the PK-232, PK-232MBX and PK-232/DSP is easy. If you
have installed a PK-232MBX or DSP daughterboard, you already know
how to install the PK-232/PSK daughter-board. It’s as simple as
plugging in the daughterboard, soldering a few connections, and
clipping a couple of component leads. There are some variations of
the procedure, depending upon which version of the PK-232 you have.
The upgrade comes with complete instructions, in addition to
Timewave’s on-line and telephone support. Dealer and factory
installation and custom cables are also available. If you use your
existing PK-232-to-Radio AFSK cable set, you’ll have no cables to
build nor complicated plugboards to patch.
