Introduction This past year I was able to successfully receive CubeSats ENSO, Veronika and EIRSAT-1 (Ref.1/3). All three CubeSats have since decayed from orbit according to the SatNOGS database. Doing a search, I found a recent CubeSat launch CANVAS (Ref.4). So I thought I would try reception using my 2m/70cm yagi. I previously used an… Continue reading CubeSat CANVAS on GNURadio

Introduction In the previous post I was able to receive MSK144 meteor scatter transmissions on 6m using the RTL-SDR (Ref.1). I thought it would be worthwhile to see how robust this protocol is using a simple GNURadio channel model. In the QEX design paper the following performance figures are given (Ref.2):SNR>0dB, almost all frames decoded… Continue reading Meteor Scatter MSK144 Channel on GNURadio

Introduction I first learned of Meteor Scatter communications during the late 1980s in connection with sending meteorological data from remote locations. The principle made a lot of sense, using natural occurring phenomena to aid in transmission of signals with simple and minimum equipment. Weather sensor data could be collected and sent back using a solar… Continue reading RTL-SDR for Meteor Scatter

Introduction Last Saturday I was able to receive Meteor M2-3 down at Toronto Harbourfront (Ref.1). So I thought it would be interesting to try and receive it from my home location. At Harbourfront, there was some signal loss due to QRM. At my home QTH there was no QRM, but some multipath and obstruction. A… Continue reading RTL-SDR for Satellite Weather – Meteor M2-3+

Introduction Last October 2025 I was able to Receive Satellite Weather from Meteor M2-3 down at Toronto Harbourfront using a Vee dipole. This spring I thought I would try the same thing but using a 2m/70cm Yagi antenna instead (Ref.1). Equipment Setup Figure 1 shows the equipment setup. I initially tested the Yagi earlier this… Continue reading RTL-SDR for Satellite Weather – Meteor M2-3
