While shortwave may conjure up images of bulky metal boxes filled with vacuum tubes, manufacturers have co-opted microelectronics to greatly improve how their radios operate while reducing size.

Septentrio introduced the AsteRx SB3 ProBase, the latest generation of GPS/GNSS base station receivers, designed for the creation of top-quality measurements for RTK and differential corrections.

Unfortunately, analog shortwave radio transmissions are notorious for interference and signal dropouts. For listeners in other countries, the sound coming out of their shortwave radios lacks the ...

[Mikrowave1] had a Unelco shortwave receiver as a kid. This was a typical simple radio for the 1960s using germanium and silicon transistors. It also had plug-in coils you had to insert into socket… ...

Today’s shortwave numbers stations are very much a legacy of the Cold War. The fierce espionage battles between the West and the Soviet Bloc — and their mutual vigilance in ferreting out each other’s ...

As mentioned, knowing the exact location of your base station is crucial to this project. There are several ways to obtain it.

The integrated µModule receiver reduces board space and development time for wireless base stations implementing PA linearization with digital predistortion (DPD). DPD addresses the most significant ...

Despite the advent of satellite and internet broadcasting, shortwave radios still have an important role to play. The Yamata Transmitting Station is broadcasting NHK’s World Radio Japan program.

What also ended up in the museum is the shortwave. Anyone who wanted to listen to international radio in the past had to have a shortwave receiver. That is also a thing of the past today.

Like many car radios and stereo tuners, these have a display which reads a station’s exact frequency while the user turns a tuning knob or takes advantage of a “scan” feature (which locks ...
