It's desirable to use FCD or RTL-SDR in order to receive Meteor-M N2 signal. Meteor-M N2 heard ! 10:46-11:01 UTC, 7 Oct 2014, Ele 50 SE-E-N, 137.100MHz WFM SDR# settings: WFM, Filter bandwidth 130000Hz over, Step size 50kHz SDR# settings by DK3WN Meteor-M N2 heard by JE9PEL [Supplement] by I6IBE Hi, for those who have a DONGLE RTL2832 has the ability to capture and view images in high resolution LRPT of the new Russian satellite called METEOR-M2 frequency 137.100 MHz, broadcasts are received and recorded in DIGITAL BASEBAND so with the software SDRSHARP, the generated WAV audio files sampled at 90 KHz go 'converted with AUDACITY to 130 KHz and saved again, this WAV files will be processed by the software LRTPRX.exe that generates and saves the files in RAW format, the files will be processed as soon as decoded by softwarte LRPTOFFLINEDECODER.exe that restiuira' image color RGB format BITMAP. The decoding process sounds complicated, in reality once you're comfortable, operations will become simpler and faster, down the vital parameters and settings for the decoding of high resolution images. For test I used a dongle rtl2832 chip R820T, as the antenna QFH Paintings Spinning propeller with only 7 meters of cable H-155, good reception at all. (Italian Original) Salve , per chi dispone di un DONGLE RTL2832 ha la possibilita di catturare e visualizzare le immagini LRPT in alta risoluzione del nuovo satellite russo denominato METEOR-M2 sulla frequenza 137.100 MHz , le trasmissioni in DIGITALE vengono ricevute e registrate in modo BASEBAND con il software SDRSHARP, il files audio WAV generato campionato a 90 KHz andra' convertito con AUDACITY a 130 KHz e salvato nuovamente, questo files WAV verra elaborato da l software LRTPRX.exe che genera e salva lo stesso files in formato RAW, il files appena elaborato verra decodificato dal softwarte LRPTOFFLINEDECODER.exe che restiuira' una immagine a colori RGB formato BITMAP. Il procedimento di decodifica sembra complicato, in realta una volta presa confidenza , le operazioni diventeranno semplici e veloci, in basso i parametri vitali e i settaggi per la decodifica delle immagini alta risoluzione. Per le prove e test io ho utilizzato un dongle rtl2832 chip R820T, come antenna la QFH Quadri Filare Elica con soli 7 metri di cavo H-155, buone ricezioni a tutti.

Received by JA0CAW, Analyzed by JE9PEL, SDR#, USB 8 Bit PCM 00:09-00:24 UTC, 20 Oct 2014, Ele 79 N-W-WS, 137.100MHz USB [Update] 'LRPToffLineDecoder' was updated to '', and this file be able to download at the following Russian site. When you unzip it, two files of exe and ini files are generated. There are the need to modify two places in this ini file. You rewrite in the 7,8 line of the above in this ini file. Then you disable it with a semi-colon (;) at the beginning of this line. And you rewrite a line of 'path = .....' at the bottom in this file to suit your PC environment as the following example. path=c:\Program Files\meteor2\LRTPRX\z The received file from Meteor-M N2 is first converted by Audacity.exe and LrptRx.exe, and there is a need for cumbersome process of applying it to this LRPToffLineDecoder. This time, I tried to analyze test of 'LRPToffLineDecoder_2014.11.13.0014'. Sound source that was used to experiment is the raw file received by JA0CAW on 20 Oct, 2014. You can be downloaded from the following Dropbox site. Because it is the raw file after it has finished the conversion by Audacity and LrptRx software, you will be able to apply this raw file immediately to this LRPToffLineDecoder. Once LRPToffLineDecoder starts, you press the button 72K. After you select 'all(*.*)', the analysis will begin when you select this raw file. The result of the analysis is shown below. When you press Generate RGB- Save button at the end, it is taken as a BMP or JPG file in your PC. I could confirm that 'LRPToffLineDecoder_2014.11.13.0014' works correctly.

It's extremely simple to use and requires nothing more than an operational copy of SDR# Revision 1110 or newer. SDR Sharp Plugins v1.6.1 READ_ME.txt: I recommend you read the Installation section of the User Guide. If you don't do so, at least follow these instructions: Unzip the file to a convenient folder. * DO NOT unzip it to the SDR# folder for this will cause the plugin installation to fail. Please run program PluginsSetup.exe to install the plugins. * DO NOT install the documentation to the SDR# folder. If the installer has no Next, Back, or Cancel buttons displayed, this is often because the screen's DPI (screen dots per inch) is set higher than 100%. Temporarily reduce the DPI to 100% and run the installer. Thank you for using my plugins!
