Radioberry - a HF Transceiver Radio PiHat for the Raspberry Pi
The Radioberry is actual a radio card (Raspberry Pi 4 Hat) installed with the latest hardware V.Beta5, which can be plugged into a Raspberry Pi 4, forming a Software Defined Radio (SDR). RPI4 is the target for running the Radioberry.
The radio card uses an Analogue Devices AD9866, which is a 12-bit broadband modem mixed signal front end that has been repurposed as a direct down conversion (DDC) and direct up conversion (DUC) SDR transceiver covering 0-30 MHz. So this covers the HF frequency range (not VHF/UHF out of the box), and can transmit up to 100 mW power.

The sBITX is a fully open source hackable self-built (and repairable) SDR Ham Radio transceiver based on a Raspberry Pi
Cheap, easy to use SDR dongles are an immensely powerful tool for learning about radio technology. However, building your own SDR is not something too many hackers are confident to tackle. [Ashhar Farhan, VU2ESE] hopes to change this with the sBITX, a hackable HF SDR transceiver designed around the Raspberry Pi.
This project is not for the faint of heart, but the downstream benefits are amazing: It can be easily extended through software updates, you can hack the software to experiment on your own, parts are all replaceable, and it potentially costs under $100 to build vs paying $2,000 or more for a commercial radio. The downside is the PDF does explain it better, but there is still no easy 1-2-3 step guide available, but I'm sure someone will come to the fore to also produce that.
Ashhar has also produced an open source buildable antenna tester.

An Overview of How to Use the Open Source OpenWebRx Web-Based Radio Receiver to Listen to Remote Radio Transmissions
OpenWebRx allows anyone worldwide with Internet browser access to listen to radio transmissions at the location of the receiver. Depending on the OpenWebRx configuration this could be broadcast FM stations, ham radio stations (various modes), two-way radios, APRS, etc. For ham radio digital modes it can decode the signal into audio and text.
My video explains what it can be used for, and I give a tour of the interface showing you how to operate it.

Home but never alone: Celebrating World Amateur Radio Day 18 April
On this day in 1925, the IARU was formed in Paris. Since then, on 18 April every year, radio amateurs worldwide have taken to the airwaves to celebrate World Amateur Radio Day. Today, the hobby is more popular than ever, with more than 3 million licensed operators worldwide, according to the International Amateur Radio Union (IARU).
We often hear about amateur radio assisting during disasters when cellphone networks and the Internet is down for extended periods, but not many know that amateurs also regularly assist with coordinating communications for large scale public events where there are areas with no cellphone coverage (car rallies, cycling tours, etc), as well as during mountain and wilderness rescue where again vital emergency communications must be coordinated between the rescue teams and emergency services. Here in Cape Town we have HAMNET who perform these services almost weekly.
The International Space Station also has amateur radio operators on board and amateurs also conduct a lot of experiments and pioneering around the use of radio still today. With just a few Watts of power an amateur can communicate to the opposite side of Earth using digital modes, and even bounce their signals off the Moon.

ITU News caught up with Lisa Leenders to learn what amateur or "ham" radio means to her as a young operator, and its role - and revival - amid the COVID-19 pandemic.

OpenWebRX is a Swiss Army Knife for SDR receivers on all bands and all modes including DMS, DSTAR, FT8, APRS, C4FM and many more
This is truly amazing software covering so many modes all-in-one including also the normal FM, AM, SSB. It actually decodes those various digital modes even identifying the caller identity and locations on a map.
There is more though... apart from just receiving it can also be configured for remote access listening, not only for yourself, but by sharing access over the Internet for others anywhere in the world. So you can test drive it by accessing some of these other stations and seeing how it operates (Receiverbook link on their website).
All it needs to run is a Raspberry Pi/Linux with a SDR (Software Defined Radio) dongle and the OpenWebRX software installed.
