PSATOR Beta version 0.05 - May 1994
-----------------------------------
This beta version replaces version 0.01.
Line version 0.01, this version of PCTOR is intended specifically for
use in conjunction with a PSA PC soundcard, such as the Cardinal Pro-16
and Pro-16 plus, Orchid Soundwave 32, Western Digital, Echo Speech,
Wearness etc. It will be called PSATOR.
PSATOR now contains DSP support to select and load appropiate HF DSP modem
code into the sound card's DSP memory. The DSP on the sound card implements
a high-performance HF modem and provides all critical timing -
the PC software takes care of AMTOR bit-assembly as well other user
interface duties.
Presently a full AMTOR implementation is included - PacTOR support
includes only read-only functionality.
A few notes on using the software.
----------------------------------
1. The software will ONLY work with PSA PC soundcard such as those
mentioned above.
2. Using the software will overwrite any DSP code that was installed
during system bootup. To restore SoundBlaster compatibility, please
reboot your system, or alternatively use dynamic device driver
installation of the sound card software.
3. The DSP software assumes that port 220h and 530h is available for
installing the plug-and-play hardware/software. Interrupt 7 (LPT1)
is also used, but is restored after PSATOR terminates. These port addressed
and interrupt number will be configurable in future versions.
4. Presently only FSK output is supported - an RS232 port is used for
interfacing to a tranceiver. Please use the enclosed PCTOR documentation
as a guideline to interfacing with your transceiver.
5. Please use the enclosed configuration file, however, please edit
call signs and selcals as required. Please note that the PCTOR V3.07
documentation should be used for reference purposes only. New documentation
will be available with the released version of the programs.
6. PSATOR derives its master clock timing from the sound card's DSP.
A special parameter is included in the configuration file, i.e.
timing:16000
Please adjust this parameter to suit your card's clock speed after using the
clock adjustment procedure in PSATOR's main menu ("T" option).
7. The speaker sound level may also adjusted using the "B" option in the
main menu - it may then set in the configuration file for future useage.
olvl:50 (valid values 0 - 64)
8. Presently support for only two modems are included, i.e. AMTOR and
PacTOR. PSATOR automatically switches modems when the operating mode
is changed, i.e. when ALT-P is used to activate PacTOR. To associate
these different modems with this functionality, two additional parameters
are included in the configuration file, i.e.
amtormdm:2 (selects modem2.cde for AMTOR)
pactormdm:3 (selects modem3.cde for PacTOR)
Further modems will be available that will include phase continuous
FSK (AFSK) as well as alternate low-tone pairs.
9. Please check that a COM port is selected, and that IRQ 3, 5, or 7
have been selected. The default is 7 (LPT1).
6. To run the software:
-----------------------
a) Verify that the following files are in the same subdirectory where
PSATOR will be loaded from:
mon.ld
modem2.cde
modem3.cde
b) PSATOR ----- this will run the user interface and load the
DSP modem as specified in the .CNF file
PSATOR will boot in AMTOR mode.
c) The sound that you hear though the sound card's speakers is the signal
after passing through the pre-filter bandpass filter of the demodulator.
d) Use the tuning bars on the upper left-hand of the screen for tuning
accurately to the signal. Use the least amount of audio to saturate the
displays.
e) To use PacTOR use ALT-P function after PSATOR have been started. Please
do not run PACTOR as a stand-alone program
Good luck and enjoy.
