A mini computer is enough to set up an SDR receiver


These micro computers are strong enough, no wonder radio hams make good use of them for DIY projects.
SDRplay have also compiled an image file with software needed for using your SDR. You just need to copy it to a Micro SD card and you can start listening on the radio bands.

RTLSDR through the eyes of an SWL observer over the past 8-10 years

SDR radio became popular in Hungary around 2012-2013 thanks to the RTL chip versions appearing among DVB-T Chinese USB TV receivers. Back then you couldn’t get these devices in Hungary, you had to order them from China. Since then the situation has changed a lot here, too.

Introducing the new 5W Dual Band Digital Transceiver – Yaesu FT3DE!

The new Yaesu FT3DE provides reliable 5W RF power output in compact design and light weight from factor - W62mm x H100mm x D32.5mm/ 282g. Battery power-saving settings are available for each frequency band with TX output power level (5W/ 2.5W/ 1W/ 0.3W) individually selectable. Even in a compact body, the user can enjoy loud and clear C4FM voice quality from 700mW of audio power. Real Dual Band Operation (V+V, U+U, V+U, U+V) are available with two independent receivers, and the FT3DR/E supports simultaneous C4FM digital monitoring for both the A and B bands (C4FM/C4FM standby).
