Very poor band condition on 40m today morning. Most likely it is due to the recent coronal mass ejection from the Sun disrupting radio propagation through the ionosphere.
Yesterday VE3NEA shared the link for SkyRoof v.1.00 beta, an SDR-based satellite tracking program. It is a freeware and open source. Hardware requirement is any modern 64 bit
Raspberry Pi Pico is a powerful microcontroller from the Raspberry Pi Foundation. NEMA 17 stepper motor is widely used in robotics and 3D printing projects. Unlike the usual
Here I am going through the steps which I followed for setting up RTL-SDR for receiving APRS from International Space Station. I could not receive any signals, probably
VU7T Lakshadweep Islands Dxpedition 2025 is active from Agatti island using vertical antennas for 40-10m and on QO-100, in spite of the inclement weather due to early onset
Function of the BOOTSEL button in Raspberry Pi Pico is discussed first, followed by familiarizing with the pin numbers. Next step is to download and install Thonny, Python
There was a 49 degree maximum elevation pass of international space station here. Decided to track it with Gpredict, RTL-SDR and 40-10m inverted V fan dipole antenna. During
Raspberry Pi Pico is a microcontroller while Raspberry Pi 5 which I had shown earlier is a single board computer. Cost is much lesser than that of Raspberry
