RTL-SDR Dongle


RTL-SDR Dongle: LT-DT307/PK
Universal Serial Bus Devices - RTL2832U
Windows7 + RTL-SDR(USB) + SDR# Ver1.0.0.1327

       


I installed firstly "MixW3" and "MixW serial port bridge" in Windows7.
and I tried the experiment that input the signal directly to PC from
the radio, not SDR. And I installed "VSPM" in PC of Windows8.1(64bit).
For details, See my_HP: mix3win7 and mix3win8.

       

Secondly,
Copy "SDRSharp.FreqEntry.dll, SDRSharp.SatelliteTracker.dll, rtlsdr.dll" etc.
in the same SDRSharp folder. And copy all files in rtl-sdr-release folder to
SDRShrap folder. Add the following sentence in config_file and xml_file.
Then, it will recognize "RTL-SDR / USB" devise.

[SDRSharp.exe.Config]
 <add key="RTL-SDR / USB" value="SDRSharp.RTLSDR.RtlSdrIO,SDRSharp.RTLSDR" />
[Plugins.xml]
 <add key="Freq Entry" value="SDRSharp.FreqEntry.FreqEntryPlugin, SDRSharp.FreqEntry" />
 <add key="SatelliteTracker" value="SDRSharp.SatelliteTracker.SatelliteTrackerPlugin,SDRSharp.SatelliteTracker" />


PPM (Parts Per Million) calculation example:
  PPM=(1-(144.660/144.6623))*1000000=16

  Enter "-16" in the box of "Frequency correction (ppm)" in SDR# - Configure(gear),
  becauce you are un-check "Swap I&Q" in "Radio" of SDR# startup screen.

I received Perseus-M1 signal. PC/Win7 or RTL-SDR Dongle is a very nice reception
performance. The figure below is the data that has been received at 22:51 JST,
December 8, 2015, but it has become a display of the delayed date as December 7.
13:47-14:00 UTC, 8 Dec 2015, Ele 66 NE-E-S, 400.170MHz 9600bps GFSK

Primary Sever of DO-64(Delfi-C3) is now updated to "131.180.122.144".
00:16-00:28 UTC, 29 Dec 2015, Ele 60 NE-E-S, 145.867MHz 1200bps USB

I decoded AO-73(FUNcube-1) using RTL-SDR Dongle, not FUNcube Dongle.
23:56-00:08 UTC, 31 Dec 2015, Ele 42 NE-E-S, 145.935MHz 1200bps BPSK

       


I solved the overflow problem of UWE-3 Online Telemetry Decoder in setting
my PC to English mode from Japanese mode, 3 Jan 2016.

UWE-3 online test successfully

  UISS setting up with Interface
  NO-44, ISS Split QSO
  APRS (Automatic Packet Reporting System)
  Soft_TNC Reception and Transmission Test


[NOTE]
In subsequent experiments, I succeeded in replaying the sound source after
installing "MixW serial port bridge" or "VSPM" to Windows 7. However, SDR#
don't run with an error message after MixW run.  Then I can recover when I
connect or disconnect RTL-SDR (USB). I am currently investigating the cause.
The line of "RTLSDR-SDR#-Soundmodem-AGW" is nothing trouble, and I can receive
the signal from the all satellites in a very smooth status without any trouble.
