Introduction In previous posts I looked at receiving GMDSS/DSC HF & VHF signals using a Windows 10 laptop with SDRangel & Multipsk as well as a RaspberryPi4B with Gqrx & GNURadio (Ref.1/5). I also simulated the VHF DSC signal using Scicos (Ref.2). In this post I will make an initial pass at decoding the VHF… Continue reading Marine GMDSS/DSC VHF Decoder_a

Marine HF Weather Fax on SDR-IQ
Introduction Several years ago I looked at receiving Marine HF Weather Fax broadcasts using the RTL-SDR & HF Up-Converter (Ref.1/2). In this post I will use the SDR-IQ HF receiver. The SDR-IQ was one of the first SDRs on the market and covers the HF band exclusively. I like it because it has excellent performance,… Continue reading Marine HF Weather Fax on SDR-IQ
RTL-SDR for NOAA15/18/19 Satellite Weather_b
Introduction In previous posts several years ago, I looked at receiving NOAA15/18/19 satellite weather using various configurations with a Windows 10 laptop and a RaspberrPi4 (Ref.1/4). To bring in the new year, I thought I would check out the latest reception. In the last post I used SDR# with noaa_apt & wxtoimg (Ref.1). In this… Continue reading RTL-SDR for NOAA15/18/19 Satellite Weather_b
