Tips on how to use GPredict can be found online at the developer’s site. There are other ways to do this as well, just be sure what method you use has the most recent prediction data. Knowing when a satellite is passing overhead is also important. This device connects in between the antenna and the DVB-T device.įinally, I used SMA cables with the appropriate male/female connectors to link up all of the hardware, these are easy to find on Amazon. I use a 12 volt source from an ATX power supply at my work bench or a 9 volt battery when outside. The amplifier is powered by a 7-13vdc source. Amazon sells them, do a search for “WideBand Amplifier”. This is inexpensive and I can use if for other RF related tasks. These are available on Amazon, search for “SMA female PCB panel edge mount plug”Īnother item that I used was a radio frequency wide band amplifier that boosted the signal. I used a SMA female PCB panel edge mount plug for my antenna. I adjusted the length of the antenna based on the operating frequency of 138Mhz. The antenna shipped with the DVB-T USB device isn’t well suited for receiving NOAA satellite signals, so I made one based off of the instructions from NWS. I’ve found that the GQRX release under Ubuntu doesn’t work as expected, so I refer to this link. I have used 2 different programs, GQRX on linux and SDRSharp on windows. I won’t go into further detail about it here, there are plenty of details about it online, for example. It’s the typical DVB-T USB device most commonly used for SDR. These were the pieces used in my setup and some description about each. There are several items needed before having a finished image. This post will be about my experiences and ideas on how to improve the process I used.
There are plenty of examples online ( ) on how to receive images from NOAA satellites using SDR.
