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+
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
NanoVNA for 400MHz/70cm BPF+LNA Testing
Introduction Last year I was successfully able to receive cubesats EIRSAT-1, Veronika and ENSO. A key element in their reception was a 433MHz BPF+LNA (Ref.1). Recently new cubesats have been launched, but working at a frequency closer to 400MHz. My existing LNA is broadband but the BPF cuts off above 400MHz so it can’t be… Continue reading NanoVNA for 400MHz/70cm BPF+LNA Testing
PlutoSDR for WSPR on 2m & 6m_a
Introduction In previous posts, I looked at WSPR & FT8 as part of the WSJT-X protocol suite (Ref.1/6). In Ref.1, I reviewed the WSPR protocol and simulated it in Scicos. I received the signal using the RTL-SDR with HamItUp converter on 30m at 10.1387MHz. In Ref.3 I tested the PlutoSDR for possible application as a… Continue reading PlutoSDR for WSPR on 2m & 6m_a
Yagi Antenna for 138MHz Satellite Weather
Introduction Receiving Satellite Weather signals at 136/138MHz has been very exciting over the past several years. NOAA15/18/19 are now deactivated, but Meteor M2-3 & M2-4 are still available. I was able to receive these signals at Toronto Harbourfront with an open sky view (Ref.1). However, at my home QTH, this proved to be difficult with… Continue reading Yagi Antenna for 138MHz Satellite Weather
