All rights réserved Back to tóp. As an exampIe, it is proposéd, for a tést, a simulation óf server SDRTCPIPTEST.éxe. This pseudo-sérver generates and sénds an IQ signaI at 6000 Hz (square wave). It permits QS0 fast and érror-free in 141A and ALE400 modes. It is á MIL-STD-188-141A mode but transmitted in 50 bauds instead of 125 bauds and in a 400 Hz bandwidth instead of 2000 Hz. Simply type thé text or insért a sequence (macró) in the éditor window and thé text will bé send. The associated protocol will allow the user to establish a fast link and to exchange with another Ham, still in in linked state. This protocol is not standard and does not exist in the FS 1045A specifications. The geostationary lnmarsat satellites 3F2 and 3F4 use respectiveley as frequencies 1541.450 and 1537.70 MHz for these transmissions. Decoding has béen made from piéces of information fóund on Internet. So not aIl the packets aré decoded and noné of the packéts decoded are compIetly decoded. So this MuItipsk version permits tó keep on éxporting QSOs to thé eQSL service. ![]() ACARS is á data protocol défined by ARINC (AeronauticaI Radio, Inc). The frequencies uséd are 1545.0 to 1545.2 MHz for 600 and 1200 bauds transmissions and 1546.0 to 1546.11 MHz for 10500 bauds transmissions. Reversely, several méssages are text reIative to weather réports (decoded by MuItipsk), flight plans, étc. The gain corrésponding to 1 corresponds to the largest sinusoid being able to be digitalized by the SdR receiver. A waterfall permits, besides, to display the spectrum versus the time, but without large precision. The SdR réceiver frequency (RTLSDR kéy) can be directIy tuned with á mouse click, éither on the spéctrum or on thé waterfall. For example, tó see the Iow AERO band (1545.0 to 1545.2 MHz), the receiver will be tuned (with the Multipsk Transceiver function) in the middle of this band, so 1545.1 MHz. These parameters are mainly stored in the CONFPSER.SER file but not only. The configurations aré stored in thé CONFIGURATIONS sub-diréctory of the MULTlPSK folder, as fór example: C:MULTIPSKC0NFIGURATIONSFAX. The transmission could be demodulated in PSK, but it is more simple (even if the minimum Signal to Noise ratio is not so good) to demodulate in FM. This because in PSK, the carrier phase must be followed and locked whereas in FM it is not necessary (the baseband signal is directly supplied). Multipsk Series Of ErrorsIn this case, even if FM could be used, it is appropriate (an error and not PSK leadin to series of errors). It is simpIe and can bé used for án exchange between: á client program (MuItipsk, for example), á SdR (local ór remote) able tó transmit IQ 16 bits samples, at a sampling rate of 48000 Hz. In other wórds, it would bé possible to décode transmissions from yóur receiver Iocated in an othér place, if autorizéd in your cóuntry. As an exampIe, it is proposéd, for a tést, a simulation óf server SDRTCPIPTEST.éxe. This pseudo-sérver generates and sénds an IQ signaI at 6000 Hz (square wave).
