On a @raspberrypi.com where I had Pi-Star installed for DMR, I thought I could install radiosonde_auto_rx as a service to track radiosondes and use of SDR & antenna. Encouraged by the success, I installed @direwolfdigital.com to APRS, and now I installed rtl-ais to track AIS signals from vessels
Dado que hay costelaciones de satélites (p.e. Starlink 10.000) de baja órbita (unos 500 km) que permiten que desde un mismo punto del planeta se vean simultáneamente varios de ellos (hasta unos 15) es posible que los satelites pueda monitorizar (espiar) en tiempo real un punto concreto.

Un año mas los radioaficionados de todo el mundo celebramos nuestro día

Temtem: Pioneers sees the light of day!
A new adventure in the Temtem universe is blooming, a blend of creature collection, survival, and fast-paced combat action set in the mysterious Downbelow.
Will you answer the call, Tamers?

Yesterday ... Temtem Pioneers @temtem.gg
For both kids and adults, Morse Invaders (www.morseinvaders.com) and Morsle (morsle.fun) are brilliant and addictive tools for learning Morse code (CW).
I copied today's #Morsle at 40 WPM on hard mode! morsle.fun
The USB2RIG dongle is a compact interface that connects the Xiegu X6200 to a Windows computer for digital modes (FT8, FT4, etc.).
Now, audio & PTT work fine, CAT is the next station.
Hoy me he almorzado con que la nave Artemisa II disponer de un sistema de comunicación de alta velocidad que hace uso de tecnología láser.
Ayer me enteré que China disponía de un sistema de comunicación vía satélite lunar que da cobertura a toda la luna.

Easter Sunday
Radiosonde running in a Raspberry Pi with a SDR dondle (green clone).
Hoping the Easter Rabbit leaves me a radiosonde.
FT8CN & FT8TW opens up new ways of making QSOs.
FT8TW for Android is more advanced than FT8CN, but neither of them is a stable version, and both require debugging work to be 100% operational.

The LWA will be a low-frequency radio telescope designed to produce high-sensitivity, high-resolution images in the frequency range of 10-88 MHz. This will be accomplished with large collecting area spread over an interferometric array at least 400 km, in New Mexico
