CLOCK 1.8.1 (FRANCE-INTER, DCF77, HBG, RUGBY, WWVB, WWV, WWVH, CHU, JJY, GPS, Internet) MULTIDEM 2.1.2 Modulator/demodulator for DSB and SdR transceiver Pour les francophones: la version française de ce message se trouve sur mon site (http://f6cte.free.fr). Il suffit de cliquer sur le lien "Principales modifications (courriel avertissant de la sortie de la nouvelle version)". Hello to all Ham and SWL, The new releases of MultiPSK (4.9), Clock (1.8.1) and MultiDEM (2.1.2) are on my Web site (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 isTerry's: http://www.hamshack.co.uk/ Multispk associated to Clock are freeware programs but with functions submitted to a licence (by user key). The main modification of CLOCK 1.8.1 and MultiDEM 2.1.2 is the replacement of the old help system (based on .HLP files) by a new help system based on .CHM files, this to be Vista compatible. The main modifications of MULTIPSK 4.9 are the following: 1) Decoding of the professional mode DGPS (limited to 5 mn without Multipsk licence) Differential Global Positioning System (DGPS) permits to improve the GPS accuracy (down to several meters). It uses a network of fixed ground based reference stations to broadcast the difference between the positions indicated by the satellite systems and the known fixed positions. The DGPS stations frequencies are situated between 283.5 and 325 KHz. See specifications further on. 2) Addition of a "Packet repeater" function (limited to 10 mn without Multipsk licence) This "Digipeater" function works in 1200, 300 and 110 bauds. The repeater has a presence signalling function (one UI frame " F9XYZ IS READY TO REPEAT ANY PACKET FRAMES" per minute). It is reminded that Multipsk has also an APRS repeater in 1200, 300 and 110 bauds. 3) For ALE/ALE400, addition of ARQ DTM/DBM messages, non limited in length. This way to send and receive a message is available on PCAle, MARSAle and several transceivers. The DTM or DBM message can be transmitted either in non-ARQ or in ARQ mode. In ARQ (Automatic Repeat Request) mode, there is no error in the transmission of the message. Each frame is transmitted until being acknowledged by the other Ham program. However after 7 retries, the link is considered as broken and the transmission stopped. ARQ DBM is the advised way to send messages. Note: the new ALE frequencies are on http://www.hflink.com/channels Here are several among the proposed ones: 3596.0, 7040.5, 10145.5, 14109.0, 21116.0 Khz 4) For ALE/ALE400, in ARQ FAE, the new protocol 1.5 (in my WEB site) will allow the user to establish a fast link and to exchange with another Ham, still in linked state: * conversation (chat) error-free messages, * mails with ou without files (small compressed pictures, for example), * APRS positions, with automatic display on the APRS map on reception. 5) for ALE/ALE400 in ARQ FAE responder, possibility for the responder to automatically send a pre-defined file. This can permit, for example, by connection to the responder to receive an updated measurements file, the file being transmitted without error. 6) APRS and SYNOP/SHIP maps: a very easy and quick way to do maps matched to the user's needs is to use the WEB application http://www.sailwx.info/maps/shipplotter.phtml. After having prepared the map you want, you have no more that to download the image file (.JPG) and the calibration file (.CLB) in the sub-directory MAPS of the Multipsk directory. Of course the mantissa of both files must be the same (for example: "France.JPG" and "France.CLB"). The CLB files will be recognized and taken into account by Multipsk. 7) Replacement of the old help system (based on .HLP files) by a new help system based on .CHM files, this to be Windows Vista compatible. For the ones interested by APRS, I have written a small English paper called "APRS_easy_with_Multipsk". In this document it will be found 4 snapshots of Multipsk screen with indications to the " how to operate ", and which show the basic functions of APRS in Packet 1200 bauds mode (QRG : 144.800 Mhz in FM). Note about translation of Multipsk.exe and Clock .exe: the 4.7 version of Multipsk has been completly translated to Spanish by Joachin (EA4ZB), from French. The translation file is on my Web site (http://f6cte.free.fr). The modifications 1 and 2 are functions submitted to a licence. For information, for all the Multipsk exotic modes (PSKFEC31, PSK10, PSKAM, PSK63F, PSK220F (+DIGISSTV), CCW-FSK, MFSK8, THROBX, DominoF, DominoEX, PAX, CHIP, Voice, Packet 110 bauds...), I propose the QRP frequency: 14075 Khz USB (AF around 1000 Hz), at 17h00 UTC. 73 Patrick DGPS Differential Global Positioning System (DGPS) permits to improve the GPS accuracy (down to several meters). It uses a network of fixed ground based reference stations to broadcast the difference between the positions indicated by the satellite systems and the known fixed positions. These stations broadcast the difference between the measured satellite pseudoranges and actual (internally computed) pseudoranges, and receiver stations may correct their pseudoranges by the same amount. Description: Baud rate : 100 or 200 Modulation : MSK (can be decoded either as a FSK or as a PSK mode. Multipsk decodes it as a PSK mode) Reception mode: USB or LSB (but USB preferably) Character set : the symbols can be ASCII characters (8 bits) in Messages of type16 but, in general, they are data. Bandwidth : about 150 Hz at 100 bauds and 300 Hz at 200 bauds, Demodulation : coherent Synchronization: automatic using the signal Lowest S/N: about -6 dB at 100 bauds and -3 DB at 200 bauds (assessment) The mode is described in the recommendations ITU-R M 823 and RTCM SC 104.. There are different types of message. A message is composed of a header of two words and 0 to 31 of information words. There are 63 types of possible message. Multipsk decodes the main ones: * Message type 1: Differential GPS corrections * Message type 3: GPS reference station parameters * Message type 5: GPS constellation health * Message type 6: GPS null frame * Message type 7: DGPS radiobeacon almanac * Message type 9: GPS partial correction set * Message type 16: GPS special message (information text) The frequencies used are in LF: 283.5 to 325 KHz. The transmitters are located near major waterways and harbors.
