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

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. Equipment Setup Figure 1 shows the equipment setup for receiving NOAA15/18/19 satellite weather. In… Continue reading RTL-SDR for NOAA15/18/19 Satellite Weather_a
RTL-SDR for HF Marine GMDSS/DSC on SDRAngel
Introduction In previous posts I looked at decoding GMDSS/DSC HF & VHF signals using Multipsk on a Windows 10 Laptop & RaspberryPi4 (Refs.1/5). In this post I decode HF DSC signals using SDRAngel on a Windows 10 laptop. GMDSS/DSC HF Reception Parameter MF/HF VHF Frequency 2187.5, 4207.5, 6312.0, 8414.5, 12577.0, 16804.5 KHz 156.525MHz Baud Rate… Continue reading RTL-SDR for HF Marine GMDSS/DSC on SDRAngel
CelNav Sept Full Moon Lunar Distance
Introduction I am reading a fascinating book about the ocean depths by Susan Casey (Ref.1). She describes an ancient chart by Olaus Magnus of Sweden, depicting in graphic detail the oceans around Scandinavia and the monsters hiding in the depths, waiting to devour unsuspecting sailors (Ref.2)! I immediately thought of Joshua Slocum sailing alone around… Continue reading CelNav Sept Full Moon Lunar Distance
VHF Marine GMDSS/DSC Decode & Scicos Simulation
Introduction In previous posts I looked at decoding GMDSS/DSC signals using Multipsk (Refs.1/4). Recently I have been able to use my balcony again to receive HF & VHF signals. I noticed that I was able to decode VHF DSC using the USB mode, which I had previously set for HF, instead of NBFM. So I… Continue reading VHF Marine GMDSS/DSC Decode & Scicos Simulation
