Re: Decoding Meteor Satellites with RSP Receivers and SDR Sharp via RTL_TCP server

There is a nice article here on the forum for building a QFH: viewtopic.php?f=5&t=2529 You can also find references online for other QFH antennas.

Es'hail 2 QO100 DVB-S2 and SDRplay RSP1A/2/duo

Just checking to see if anyone on the forum in Europe has had a chance to receive video images from Es'hail 2 using an SDRplay RSP. There is an article here where this has been reported to be done using PC decoding software for DVB-S2 developed by Marcel Kroner here https://forum.amsat-dl.org/index....

Re: HRIT and LRIT Geostationary Weather Satellite Image Reception

Hi David, The link for the original e-Bay source for the 50ft USB extender cables that were found to work well is no longer valid. Finding 50ft USB 2.0 extension cables that work flawlessly is not easy, but most that have a large ferrite choke at each end of the cable and an active repeater circuit ...

Re: HRIT and LRIT Low-Cost System

Here are the results using the described modification: GOES 16 Before: Quality 95.1%, VT 76 EB/No 5.55dB (based on improvements described in the August 12, 2018 Post - the out-of-the-box figure without any modification was around Quality 69.7 VT 455) After Mod: Quality 98.4%, VT 26, Eb/No 6.83dB G16...

Re: HRIT and LRIT Low-Cost System

Update: simple modification significantly improves GOES 16 and 17 HRIT signal reception using Premiertek ANT-GRID-24DBI antenna. [This modification is solely meant for the Premiertek ANT-GRID-24DBI antenna. Application of this modification to other similar antennas may not have the desired results a...

Re: HRIT and LRIT Low-Cost System

Jaapyse, If you are located in Africa, a 1m grid parabolic antenna such as the ANT-GRID-24DBI may work for Meteosat 11 signal reception. If you are in Europe (particularly Northern European locations), you will likely need a larger parabolic antenna. If there are others in your area receiving the Me...

Re: HRIT and LRIT Low-Cost System

Jaapyse, The tripod was an old, inexpensive camera tripod that was stored in the garage. If you search the Internet for "camera tripod low cost" you will find similar tripods. The Premiertech ANT-GRID-24DBI comes with mounting hardware that will allow for adjustment of elevation and azimut...

Re: HRIT and LRIT Low-Cost System

Please review the discussion at the top of p. 3 of this set of posts. If you are using a Premiertek ANT-GRID-24DBI antenna, then simply flipping over the secondary reflector provides significant improvement at 1.69GHz (closely review images of the setup as well). There have been other discussions on...

Re: HRIT and LRIT Low-Cost System

The advantage to extending the signal the distance from the antenna to the PC using a USB2.0 extender cable and locating the SDR at the antenna is that it can usually be done at a comparatively low cost and there is less signal loss before the RF signal to digital conversion and with the right USB 2...
