Introduction When working with SDR# on Windows, I can save reception data using either the ‘Baseband: Simple Recorder’ or ‘Audio: Simple Recorder’. In either case the files can be opened and manipulated in Audacity because they have a .wav file extension. The Baseband files have a sample rate equal to the Rx samp_rate and the… Continue reading Trimming SDR IQ Raw Data

Introduction Every six months or so I like to reload the RPi4B OS to see what changes have occurred. Recently I installed the Debian Trixie 64bit version and am very impressed. All the software that I commonly use installed well with no glitches. I did notice that when using the RTL-SDR and GNSS receiver I… Continue reading Raspberry Pi4B for Air & Marine

Introduction Last week I revisited receiving GOES16 which I had initially done several years ago (Ref.1/7). GOES16 has now been replaced by GOES19 and is also called GOES EAST (Ref.8). I saved the received signal as a baseband IQ file and later decoded with SatDump. In this video I will synchronously receive/decode the signal with… Continue reading RTL-SDR for Satellite Weather – GOES EAST

Introduction In a previous post I looked at a simple receiver for VHF Air Band AM (Ref.1). In this post I add several new features in order to select from a stored set of local frequencies and a choice between source blocks. GNU Radio Schematic VHF Air Band AM Receiver Figure 1 shows the GNURC… Continue reading RTL-SDR for VHF Air Band AM Receiver on GNU Radio

Introduction Four years ago I was able to receive signals from GOES16, a geostationary weather satellite located at 75.2degW (Ref.1/6). I used goestools on RaspberryPi4B. In the last post I decoded signals from Meteor M2-3/4 using SatDump. I noticed that this program also handled GOES. So I setup my dish again and was able to… Continue reading RTL-SDR for Satellite Weather – GOES16
