A few months ago I started looking at various options for omnidirectional antennas with circular polarization for satellite communications. I came across the TA-1 137 MHz turnstile antenna from Wimo, which looked like an interesting option for a reasonable price.

Two months ago I hooked up my VHF satellite receiver to the SatNOGS network. Since then, the receiver has been receiving many different satellites, including APT images from NOAA 15, 18 and 19.

Tonight I tested the turnstile antenna and Airspy on the Meteor-M N2 LRPT downlink signal. It was a good, high elevation pass and it looks like the signal is strong enough to decode the transmitted images.

Some time ago I got a 137 MHz turnstile antenna from Jørn OZ6TA. We decided to build an automated NOAA weather satellite image receiver using a modern SDR device. He also had an Airspy he wasn’t using and so it became the SDR radio we were going to use for this.

Today we have a guest post by Kirill Snezhko (@argrento) who describes how to get Gpredict working on Android tablets. Note that this is not about a native Android port of Gpredict, but how to get Linux installed as an Android app and run Linux applications like Gpredict.
