Astron Corporation Step-Down DC/DC Converters offer high-efficiency DC conversion. These down-converters change an input voltage of 22-32 Volt DC to a highly regulated output voltage of 13.8 Volts DC. These converters provide no isolation between their input and output negative terminals and are meant for use in negative-ground systems. (I.E. Vehicles)
Features include overvoltage and short-circuit protection, input-side overvoltage/transient protection, and input-side reverse polarity protection. Some possible applications include industrial equipment, heavy trucks, buses, marine vehicles, mobile radio equipment, and conversion from 24 volt aircraft systems.
If you have a need to convert your high-voltage DC to 13.8 volts, these Astron Corporation Step-Down DC/DC Converters are designed to handle all of your most demanding applications!
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.
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.
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).
SDRplay is pleased to announce the release of SDRuno v1.3. This is a major upgrade to SDRuno, which adds a number of important new features and is intended for all RSP models (RSP1, RSP1A, RSP2, RSP2pro and RSPduo)
We are excited to inform that the PDN (Portable Digital Node) function for the FTM-400 and FTM-100 series is now available. This firmware is now available at Yaesu official website: http://www.yaesu.com.
