The new releases of MultiPSK (4.21) and Multidem (2.4) 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://g90swl.co.uk/multipsk/
Multipsk associated to Clock are freeware programs but with functions submitted to a licence (by user key).

AM/FM modulation/demodulation has been added to Multidem 2.4.

The main improvements of MULTIPSK 4.21 are the following:

1) Coding / Decoding of the new mode LENTUS
This mode is used for QRP transmissions (down to a minimum S/N ratio of -34 dB) either in LF, MF and HF (14 MHz maximum) but not beyond.

The recommended frequencies (on the XCVR) are the following (with an AF frequency of 1000 Hz, in USB): 136.3, 1837.0, 3589.0, 7037.5, 10138.7, 14074.0, 14095.6 KHz.

The detailled specifications of this mode are given, in English, in the Word document “Specifications 1.0 of the Lentus mode” situated in the “Specifications” heading on my WEB site (English page).

See general specifications further on.

2) CALL_ID fixed
Due to the correction of a bug in the Call ID code source, the new CALL ID is not compatible with the old CALL ID (Multipsk versions <4.21).

3) New TCP/IP commands
To control the ARQ FAE sub-mode in 141A and ALE400

- CQ_ARQ_FAE: CQ call in ARQ FAE (for 141A or ALE400), to connect any Ham.

- STOP_CQ_ARQ_FAE: Stop of the CQ call in ARQ FAE (for 141A or ALE400) or disconnection.

- SELECTIVE_CALL_ARQ_FAE: Selective call in ARQ FAE (for 141A or ALE400), to connect a precise Ham.

- STOP_SELECTIVE_CALL_ARQ_FAE: Stop of the selective call in ARQ FAE (for 141A or ALE400) or disconnection.

- CALLSIGN_TO_CALL_ARQ_FAE CALLSIGN: Ham callsign of the selective call in ARQ FAE (for 141A or ALE400). This Ham will be, afterwards, called by the command SELECTIVE_CALL_ARQ_FAE,

- BEACON_ARQ_FAE: starting beacon in ARQ FAE (for 141A or ALE400),

- STOP_BEACON_ARQ_FAE: stop of the beacon in ARQ FAE (for 141A or ALE400).

Others
Each Lentus frequency is transmitted as a comment, for example: "1234.56 Hz". As there are 40 symbols by Lentus frame, 40 frequencies are transmitted.

- QSO_CALL: call of the callsign located in the "Call" QSO field".

4) Improvements:

- addition of the latitude/longitude in "Personal data" ("Configuration menu)

- addition of the two macros "LATITUDE" and "LONGITUDE" (taking information from the latitude/longitude in personal data)

- in SdR, addition of modulation/demodulation in AM and FM (narrow band one for Ham, not wide band one) which can be used to demodulate and then decode ACARS, PACKET, 1382, NWR with a Funcube as shown below.
About the use of AM and FM demodulation and decoding, using the FunCube Dongle:
· using the FCHid program, from the defauts adjustments, change the "IF gain 5" and the "IF gain 6" from "+3dB" to "+15 dB" so to have a sufficient AF level,
· adjust the microphone gain of the Funcube to 100% on the mixer.
Note: to change the FunCube frequency you can use either the FCid program or the FCD DF program. FCD DF is preferable due to the frequency memories.
· start Multipsk, push "Direct via the sound card" + "+Speaker" of the "I/Q interfaces for SdR transceivers" panel, then push "RX/TX screen". Possibly, push on the "QRGs" button to have some proposed frequencies for the selected mode.

· on the SdR panel, select LSB/USB/AM or FM according to the mode to decode. In all cases, click just on the central frequency of the transmission on the SdR waterfall.
To test AM: select "ACARS" on the Multipsk mode panel and 131725 KHz (for example) on the FCD DF program.
To test FM: select "PACKET" on the Multipsk mode panel and 144800 KHz in Europe (144390 KHz in North America) on the FCD DF program. 1382 (in Europe) and NWR (in USA and Canada) modes are also demodulated in FM before decoding.

5) Miscellaneous
Note about ALE400 frequency on 80 m
The area from 3581 to 3582 KHz seems preferably used in North America for QSO.
Note about translation of Multipsk.exe and Clock .exe: the 4.20.1 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).

LENTUS

LENTUS means " Slow " (but also indolent, nonchalant, quiet…) in latin.

Created by: Patrick Lindecker (F6CTE) in 2012

Description :

Baud rate : 0.1465 (4800/32768) or 6.827 seconds by 5 bits symbol

Messages: a message of 293.5 seconds duration (43 symbols) begins at t=4 sec of the UTC minute 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, or 55 (it is necessary that the PC may be synchronized on a “Standard” clock).
Note : in manual transmission, it can also start at 4+6.827=10.827 sec (42 symbols sent) or 10.827+6.827=17.654 sec (41 symbols sent) or 17.654+6.827=24.481 sec (40 symbols sent), to « pardon » the Ham operator for a delay to answer, but with reception probability a bit weaker.
The message is normally composed of 43 symbols (but can be reduced to 40 symbols, see above), each one with a length of 32768 audio samples (or or 6.827 seconds). The 9 first symbols carry a tone allowing the determination of the transmission central frequency. The 31 following "5 bits symbols" carry the message (allowing the Reed-Solomon coding of 75 bits). The last three symbols are transmission central frequency carriers.

Messages can be either plain text (13 characters, preceded by a bit “CQ de” and a bit “Beacon”) or formatted text according to different possibilities, listed below:
· A standard CQ call composed of a bit “CQ” + a bit “Beacon” + complete call (with 3 characters max in the mantissa, as for example “AZ2/FL5XYZ/MM”) + optionally, a 6 characters Locator (accuracy +/-2.31 km in latitude and +/- 4.63 km in longitude).
Note: without the “CQ”, it is an information transmitted by the Ham answering to the CQ call,

· A “Station description” type CQ call composed of a bit “CQ” + a bit “Beacon”, a 6 characters call + suffix (as for example “FL5XYZ/MM”), a “6 characters Locator” + Power level + “mW/W” bit + relative gain of HF antenna + directivity of the antenna.
Note: without the “CQ”, it is an information transmitted by the Ham answering to the CQ call,

· A “Meteorological” type CQ call composed of a bit “CQ” + a bit “Beacon”, a 6 characters call (as for example “FL5XYZ”), a “6 characters Locator” + Temperature + Wind force + Type of weather + Humidity.
Note: without the “CQ”, it is information transmitted by the Ham answering to the CQ call,

· A CQ call with precise geographical position composed of a bit “CQ” + a bit “Beacon”, a 6 characters call + a geographical position (latitude + longitude) in ° ‘ and 2 figures decimal (as for example “48-49.83N 002-22.02E”). The accuracy is equal to 9 m in latitude and in longitude (about 60000 times more precise than a Locator position).
Note: without the “CQ”, it is an information transmitted by the Ham answering to the CQ call,

· An answer to a CQ with Locator 4 characters composed of a 6 characters Call 1 ( as for example “FL5XYZ”) + 6 characters Call 2 (as for example “FL5XYZ”) + Locator 4 characters (accuracy +/-55 km in latitude and +/- 111 km in longitude), in answer of Call 1 to a CQ done by Call 2,

· An answer to a CQ with S/N ratio and drift composed of a 6 characters Call1 (as for example “FL5XYZ”) + 6 characters Call 2 + Suffix (as for example “FL5XYZ/MM”) + S/N ratio (12 to -37 dB) + drift (-4 to 4 by step of 0.1 Hz/mn), in answer of Call 1 to a CQ done by Call 2,

· An answer to finish a QSO composed of a 6 characters Call 1 (as for example “FL5XYZ”) + 6 characters Call 2 + Suffix (as for example “FL5XYZ/MM”) + “73 GB SK”.

Moments of decoding :
Reception start: the reception normally begins at t=4 sec and lasts 40 or 43 symbols (see below). In case of failure of the operator, the reception can also begin at t=24.481 sec and lasts 37 or 40 symbols (it’s a degraded working).
Decoding start: the main decoding takes place after reception of 40 symbols (i.e. 273 seconds), which normally leaves about 25 seconds to answer. However, there is still a margin of 20 seconds (to reach 25+20=45 sec), the message being, in that case, truncated but being able to be decoded.
In case of failure of the main decoding, other decoding attempts are done after 41 symbols (280 seconds), 42 symbols (287 seconds) and 43 symbols (294 seconds). In this last case, it remains 6 seconds to answer. However, there is still a margin of 20 seconds (to reach 6+20=26 sec), the message being, in that case, truncated but being able to be decoded.
Mode of transmission: Lentus can be used to do QSO (two_way communication) or as a beacon. In that last case, no answer is required:
· a beacon transmission could be done at minutes 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, or 55.
· for a QSO, by mutual agreement , the Ham calling CQ will transmit at minutes 0, 10, 20, 30, 40, 50 and the Ham answering to the CQ call will transmit at minutes 5, 15, 25, 35, 45, 55.
Repeater: Lentus can also be used, for very specific use, as a repeater. As a repeater, it simply transmits what it is received so as to forward the message to other stations or to broadcast a message (with several repeaters).
Speed : 75 bits (or 13 characters maximum in plain text) by 5 minutes period (with only one message by period) or 0,43 wpm
Modulation : MFSK 32 tones (for 5 bits) with a shift between tones of 0.7325 Hz (5 x baud rate).
The synchronization tone transmitted during the 9 first symbols corresponds to the central frequency of the transmission bandwidth. It permits to determine this frequency (with a precision of about +/- 0.1 Hz) and the drift speed (up to 3 Hz/mn). The 32 possible 10th symbol (first data) frequencies will be estimated from these two pieces of information. The synchronization frequency search bandwidth tolerance is variable from +/- 20 Hz to +/-80 Hz, counted from the frequency clicked, by the user, on the waterfall.
Receive mode: USB. Each transmitting or receive period of 300 sec must start at t=4 sec of the UTC minute 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, or 55 with a maximum tolerance of +/-0.1 sec of the PC clock. A margin of 20 seconds is given as indicated in “Messages” above.
It is possible to introduce an advance (from 0 to 0.1 second by 10 msec steps) to compensate from a possible transmission delay (due to a big distance to the zone to target or a delay due to a Wifi link, for example). Symmetrically, in reception, this advance will be taken into account as a delay to start decoding.
The time to switch the transceiver is supposed to be very short (definitely less than to 100 ms).
Characters set (46) : ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 / + – . ? ! @ % $
Shape of pulse : rectangular
Bandwidth: 23 Hz
Synchronization: using the very accurate time from an Internet Time Service as the NSIT, through a SNTP or NTP protocol (but not through the RFC-868 Time Protocol) so to have an accuracy widely better than 50 ms. The use of the “AboutTime” freeware is widely encouraged as the PC time error is determined by the soft, simply by setting time twice, the second time (and the followings) will give the PC time error.
Coding code: Reed Solomon (31, 15) or 31 symbols of 5 bits for 15 symbols of 5 information bits (so a yield of 0.48). The irreducible polynomial P(x) is equal to X^5+X^2+1.
The generator polynomial G(x) is equal to a product of (X+alpha^i) with i minimum=1.
Convolution code: no
Interleaving : no interleaving nor Gray coding is used.
Scrambling : each of the 31 Reed-Solomon symbols (which value is between V=0 and V=31), which order is defined by O=0 for the first transmitted symbol until O=30 for the last transmitted symbol, is associated with a XOR f(O). In other words, for each symbol, it is done the operation V = V XOR f(O). This is done to avoid that a carrier produces a suite of same symbols (suite which could be interpretable by the Reed Solomon coding as a correct code). At reception, the V initial is found again by doing Vinitial = Vreceived XOR f(O). The f(O) function is random.
Pmean/Ppeak: 1
Drift tolerance : 2 Hz/mn (note that the performance in S/N ratio term is degrading with drift)
Lowest S/N : -34 dB (without any drift, for more than 90 % of the frames), however some frames are decoded at -36.5 dB. At -37 dB and below, no frames are decoded.
Specifications of this mode will be found in the document “Specifications 1.0 of the Lentus mode” written the 10th of March 2012 (“Specifications” on my WEB site: http://f6cte.free.fr/).
