If you are looking for a good and useful sound card digital decoding program, I would suggest you give Multipsk a look. It is a package we use here on the Btown radio ranch. And now Multipsk just got better. I just received the following release from our friend Patrick Lindecker regarding the latest software release of his popular Multipsk sound card decoding package.
Hello to all Ham and SWL,
The new releases of MultiPSK (4.21.1), Clock (1.9.1) and Multidem (2.4.1) are on my website (http://f6cte.free.fr). The main mirror site is Earl's, N8KBR: http://www.eqth.info/multipsk/index.html (click on "United States Download Site"). Another mirror site is Terry's: http://g90swl.co.uk/multipsk/
Multipsk associated to Clock are freeware programs but with functions submitted to a licence (by user key).
The possibility to export TCP/IP data at 48000 Hz has been added to Multidem 2.4.1.
The main improvements of MULTIPSK 4.21.1 are the following:
* In GMDSS, addition of a "Traffic" window: this function permits to display all the last received GMDSS messages, collected by a specific GMDSS WEB server.
The "Traffic" button permits to display all the last GMDSS received messages, collected by a specific GMSS WEB server. In that case, Multipsk will transmit all the messages received by the user (Ham or SWL) to a WEB server. Multipsk will fetch and display all the collected Lentus messages during minutes 0, 5, 10...55. This function permits to follow ships route, beyond one's own distance of reception, to cover large areas.
Note 1: To avoid broadcasting unreliable pieces of information, only messages with correct CRC will be sent to the GMDSS server.
Note 2: GMDSS server files can be supplied (through an exchange of mails with the author) to constitute private GMDSS listening nets.
* In ACARS and HFDL, addition of a "Traffic" window: this function permits to display all the plane position messages, collected by a specific WEB server (ACARS or HFDL).
Note: ACARS or HFDL server files can be supplied (through an exchange of mails with the author) to constitute private ACARS or HFDL listening nets.
* In Lentus, addition of a "Traffic" window: this function permits to display all the last received and transmitted Lentus messages, collected by a specific Lentus WEB server.
* In DGPS, addition of information about the Station number and possibility of automatic switching to the DGPS detected speed ("Automatic" button).
* in the QSO window, possibility to find a word in the text.
* Possibility to receive TCP/IP data at 48000 Hz (to interface SdR programs, for example).
* In APRS, GMDSS, ACARS and HFDL, there is a better display on Google Earth and local maps with dashes between dots, only if the "Display all" button is pushed.
Miscellaneous
The paper "Lentus easy with Multipsk.doc" has been updated and is available on my website: http://f6cte.free.fr/LENTUS_easy_with_Multipsk.doc.
Note about translation of Multipsk.exe and Clock .exe: the 4.21 version of Multipsk/Clock has been completly translated to Spanish by Joachin (EA4ZB), from French. The translation file is on my Web site (http://f6cte.free.fr/Translation_files.htm).

New Release of MultiPSK (4.18) Now Available
Multipsk is my absolute favorite digital decoder for the computer soundcard and the author, Patrick, F6CTE, just keeps making it better. This morning he has just announced the release of a new verson of MultiPSK (v4.18). His announcement is present below in its entirety
Hello to all Ham and SWL,
The new release of MultiPSK (4.18) is on my Web site (http://f6cte.free.fr/). It is not yet on Earl's and Terry's WEB sites.
The main modifications of MULTIPSK 4.18 are the following:
1) Decoding of the NWR SAME mode
NWR (National Weather Radio) SAME (Specific Area Message Encoding) is simply a method of identifying the local area to which an alert message applies. It utilizes a digital data stream that contains the alert message with information about the type of event expected, its timing, duration, and location. The NWR SAME system is used in USA and Canada, in VHF (162.400, 162.425, 162.450, 162.475, 162.500, 162.525, 162.550 MHz).
To listen NWR SAME messages: the NWS tests the NWR and SAME alerting technology weekly. These tests normally occur on Wednesday between 10 AM and Noon with some variations to accomodate local requirements.
This mode is available for licencied copies, only (otherwise, the decoding is stopped after 5 minutes). See specifications further on.
2) Transmission/reception of ARQ FAE QSP (indirect) mails through a "mails Server"
Differences between a direct mail and a QSP mail (indirect). A mail is direct if you can transmit it directly to the final addressee: A -->B.
If you can't transmit the mail directly because the final addressee can't be directly reached due to the link conditions, the mail can be forwarded by the connected station, which acts as a "mails Server": A-->C (mails Server)-->B.
For this, you must use a QSP mail.
A paper based on snapshots presents this new system:
http://f6cte.free.fr/QSP_mails_forwarding_easy_with_Multipsk_in_ALE_and_ALE400.doc
3) New macros:
-permits to ask to the other Ham or to the SWL monitoring your QSO to send you a reception report by e-mail. Your address must be specified in the "WEB ADDRESS" of your personal data ("Personal" button). It will be transmitted the following command "RPRT@LENemail addressCRC" which is the report demand. If correctly decoded, a reception report will be transmitted to the e-mail address that you specified, through Internet.
Examples of use of this macro
1) The main objective is to ask the other Ham with whom you are in QSO to send you a reception report by e-mail.
2) But it can be also done by a SWL monitoring your QSO.
3) This macro can be used in conjuction with a Multipsk beacon which mode can be controlled by a RS ID. For example, you can switch the beacon in BPSK31 and asks the beacon for a reception report. Afterwards, the beacon can be switched in Olivia by a new RS ID and a new reception report can be asked...
Note: this macro can be used for all digital modes (except JT65), CW included.
A paper based on snapshots presents this new system:
http://f6cte.free.fr/How_to_use_thehttp://f6cte.free.fr/How_to_use_the_«RPRT@»_email_reception_report_with_Multipsk.doc
The source code (in Pascal/Delphi and in English) to code/decode this command is available for the coding/decoding software developpers, by making the demand to F6CTE by e-mail.
-permits to send a Tune (non modulated carrier) with the command: . For example: (5% of power at 4000 Hz for 1 sec)
This function can be used for transmission tests or, perhaps, to create his/her personal "jingle" (short musical sequence).
- 's' gives the Signal to Noise ratio (in dB) obtained about 4 seconds before the switching to transmission.
- 'quality' for PSK modes only, gives the signal quality from 1/5 to 5/5 obtained about 4 seconds before the switching to transmission.
4) Improvements
Addition of a filter possibility in the SELCAL mode. Addition of 6 new memories of frequency and mode in the Transceiver window, for a total of 10 memories.
Some improvements for contesters: addition of a manual control of the QSO number, proposition of standard HF QRGs for the "Freq MHz" field, possibility to double the size of the "QSO->log" or "DXKeeper" buttons (in the "Logbook" window).
Note about translation of Multipsk.exe and Clock .exe: the 4.17 version of Multipsk/Clock has been completly translated to Spanish by Joachin (EA4ZB), from French. The translation file is on my Web site (http://f6cte.free.fr/Translation_files.htm).
NWR SAME (VHF)
The NWR (National Weather Radio) SAME (Specific Area Message Encoding) is a digital system for transmission in USA and Canada, in VHF, of warning messages. There are, in fact, other agencies that NWS (National Weather Service) which use the SAME system. There are also many other messages that warning or watch messages.
Description :
Baud rate: 580.83.
Modulation : Logic 0 at 1562.5 Hz and logic 1 at 2083.3 Hz
Reception mode: FM
Character set : ASCII characters (8 bits)
Shape of pulse : rectangular
Bandwidth : about 1 KHz
Demodulation : non coherent
Bit synchronization : automatic using the signal
Character synchronization : automatic using predefined strings of characters (« ZCZC » and « NNNN »)
Lowest S/N: +4 dB
Each NWR/SAME message contains:
* 3 same digital messages containing (on a coded form) the event, the concerned areas, duration and broadcast station (for example: ZCZC-WXR-TOW-039173-039051-139069+0030-1591829-KCLE/NWS-). These messages are decoded by Multipsk.
* possibly a 1050 Hz warning alarm tone for 8 to 10 seconds,
* possibly a verbal spoken oral text of message,
* 3 digital messages « NNNN » for end of message.

Attention European Radio Readers
Patrick Lindecker, the developer of the Multipsk digital decoding software package, has pasted along the following interesting info.
-------------------------------
Hello to all European testers,
I have had the information that an helicopter or airplane of the Tour de France could use "1382" frames with GPS ($GPRMC) positions inside.
So I have issued a test version of Multipsk, in which I have added a function to display GPS positions carried in the "1382" frames either on a local map or GoogleEarth. The "1382" professional mode is only available for licencied users.
The frequency is 164,6875 MHz. The Tour de France is tomorrow (Sunday) between France and Switzeland. It could be fun to follow their positions.
The test version contains the Multipsk test version and the help files: http://f6cte.free.fr/MULTIPSK_TEST_18_07_2009.ZIP
Paste this adress in your Internet Explorer or equivalent. Download the file. Create a tempory folder (C:\TEST, for example), unzip the file in it and start C:\TEST\Multipsk.exe (the auxiliary files will be created automatically). Add your user key and the Maps sub-directory in this temporary folder.
TKS for reports.
