- PSATOR Beta version 0.10 - July 1994
- ------------------------------------
-
- This beta version replaces version 0.09A. Version 0.09A had a bug
- that made alternate input source selcetion impossible. First decide
- which input to use, i.e. line or mike. Then try the various settings,
- 0,1 or 2. Since different PSA boards have their inputs labelled diffently,
- your setting may differ from the setting in the sample CNF file.
-
- This provides AFSK output tones. The mark/space sense of the tones may
- be reversed using the OUTMASK configuration parameter. The AFSK tone
- frequencies are the same as that the demodulator use. When the low
- tone pair modems become available, the AFSK tones will also be the low
- tone pair. Please note that new modems and DSP monitor is REQUIRED
- (mon.ld, modem2.cde, modem4.cde). Older DSP code will not work with
- version 0.10.
-
- Program history ---------------
-
- Version 09/A provided a user-definable input signal source. If your
- transceiver output a higher output signal level, i.e. 2V p-p, use the
- "LINE IN". For lower levels of transceiver audio levels, use "MIKE IN".
- Experiment with the "SOURCE" input of the the AMTOR and PACTOR
- configuration file to find the appropiate input source (must be
- set in both CNF files).
-
- This version contains an overhauled tuning display module. This should be
- an improvement over the previous version. It is based on a peak detector
- that is optimised especially for either AMTOR or PacTOR. Optimal tuning
- is achieved when both channels are showing equal signal strengths - the
- audio level should be set such that the red segments just come on
- occasionally.
-
- MODEM4.CDE contains a new, better balanced, PacTOR modem.
-
- An additional status indicator, associated with ALT-I (reverse input
- signal polarity) is provided. Look for a flashing "i".
-
- Version 0.08 included user-specified PTT and data out
- logic sense. It also includes separate AMTOR and Pactor audio
- output levels.
-
- 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. It is recommended that the DSP16.SYS device driver not be included
- in your CONFIG.SYS as suggested by the Cardinal's documentation. Instead
- use a dynamic device driver loader such as PC-Mag's "DRVLOAD". The
- device driver, "DSP16.SYS" is not the usual device driver - it does
- not reside in the PC's memory, but only downloads DSP code to the
- DSP that allows it to emulate different industry standard sound formats.
- It may thus be reloaded at any time.
-
- Using the PSATOR software will overwrite any DSP code presently loaded
- in the DSP. To restore SoundBlaster compatibility, please reload
- DSP16.SYS using the dynamic device driver.
-
- 3. The Cardinal card may be jumpered to use either port 220h/240h,
- please indicate the proper setting in the configuration file:
-
- pssbase: 544 (220H) or pssbase: 576 (240H)
-
- The Windows sound port, however, is assumed to be at
- (530h) for the moment. The user is also requested to specify an IRQ -
- this interrupt will be restored after PSATOR terminates.
-
- 4. FSK (AFSK will be in version 10) output is supported - an RS232 port
- is used for interfacing to the PTT and FSK to a tranceiver. PSATOR uses
- RTS (pin 4 DB-25 .... pin 7 DB-9)
- DTR (pin 20 DB-25 .... pin 4 DB-9).
-
- 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:8000 <---- for Cardinal (and other PSA cards)
- 10000 for the Orchid Soundwave 32
-
- 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)
-
- Similarly, the line-in level may be adjusted using the "E" option in the
- main menu and subsequently set up in the configuration file.
-
- ilvl:7 (valid values 0 - 15)
-
- The trick is to set the audio level (some tranceivers have an audio output
- taken before the audio amplifier - the AF control thus do not affect
- this level) to a confortable level as monitored through the transceiver's
- speaker. Then, while tuned to some signals, adjust the line in level such
- that that the red bars in the tuning display occasionally lights up. This
- is the level to use in your configuration file. The speaker output level
- can then be set for a comfortable listening level through the computer's
- speakers or monitor headphones.
-
- Please note that PSA-PACTOR also has similar settings.
-
- 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:4 (selects modem4.cde for PacTOR)
-
- 9. Please check that a COM port is selected, and that IRQ 3, 5, 7, 9,
- 10, 11, or 12 have been selected. The default is 7 (LPT1). This not
- a permanent assignment. PSATOR will release and restore this interrupt
- when it terminates.
-
- 10. Should there be a need to invert logic levels for either the receive,
- PTT, or transmit data, please adjust the MASKIN and MASKOUT configuration
- according to the values below:
-
- MASKIN:1 --- normal mark/space
- MASKIN:0 --- inverted mark/space
-
- MASKOUT:1 --- normal PTT, normal DTR
- MASKOUT:0 --- normal PTT, inverted DTR
- MASKOUT:3 --- inverted PTT, normal DTR
- MASKOUT:2 --- inverted PTT, inverted DTR
-
- 11) You may also toggle the receive logic sense using ALT-I. Note a
- flashing "i" appears on the status line to indicate a reversed Rx state.
-
- 12) Now contains user-definable input signal source. If your transceiver
- output a higher output signal level, i.e. 2V p-p, use the "LINE IN".
- For lower levels of transceiver audio levels, use "MIKE IN".
- Experiment with the "SOURCE" input of the the AMTOR and PACTOR
- configuration file to find the appropiate input source (must be
- set in both CNF files).
-
-
- 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 ..... (AMTOR 2125/2295 100 baud)
- modem4.cde ..... (PacTOR 2110/2310 200 baud)
-
- 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.
