The Raspberry Pi has become an indispensable tool in the amateur radio shack in recent years. Whether as a digital modem controller, APRS iGate, Winlink gateway or fully-fledged WebSDR receiver — the small single-board computer…

Satellites have fascinated radio amateurs since the early days of OSCAR 1 in 1961. Today, getting started with satellite reception and even satellite communication is easier than ever before. With affordable SDR receivers, powerful tracking…

There are radio amateurs who operate. And there are radio amateurs who build, measure, solder, mill, program and repair. Karl from Tretram, OE8JHK, does both – and documents his projects properly on top. Auf seiner…

Do you want to know how far your radio signal actually reaches from your location? Whether the new repeater site on the local mountain provides optimal coverage? Or which frequency and antenna height are best…

If you’re into Software Defined Radio, you know the problem: most SDR devices are powerful but need a computer to work. Not so with the HackRF One and its PortaPack extension — a combination that…

Who wouldn’t want to make contact with an astronaut orbiting Earth at 28,000 km/h? The International Space Station ISS makes exactly that possible – and you probably already have the equipment for it in your…

“What are the conditions like today?” – every amateur radio operator asks themselves this question before going on the bands. The answer lies in a handful of key indicators: SFI, K-Index, A-Index, and sunspot number.…

A 10 cm cube racing across the sky at 27,000 km/h – and you can transmit through it. CubeSats have democratized amateur radio satellite communication: Where once huge budgets and years of development were necessary,…

Let’s be honest: who among us hasn’t asked ChatGPT how long a half-wave dipole for 20 meters needs to be? Or asked Claude to write an Arduino sketch for a CW keyer? Artificial intelligence has…

Let’s be honest: who hasn’t spent an entire evening typing repeater data into a new radio? Frequency, offset, CTCSS tone, name… channel by channel. Fifty repeaters later, your eyes are tired, your fingers are stiff,…

A real-time map for the Meshtastic network in Austria and Europe – open, live, and without tracking. We’ve all been there: your Meshtastic node is running, happily transmitting away – and then you wonder: can…

How we connect Meshtastic nodes via the internet – and how you can join in. Meshtastic is brilliant. Small LoRa nodes that communicate without internet, without a provider, and without monthly costs. Locally via radio,…

Hello everyone! Hermann here, OE8HSF, from Knappenberg near Hüttenberg – at a good 1,000 metres above sea level. You probably know the feeling: you stumble across a topic on the internet, think “I’ll just have…

You know the feeling? Standing in the garden, 42 metres of wire in one hand, coffee in the other, wondering: where is all this supposed to go? That is exactly how my adventure with the…

He knows no boundaries. No mountains. No rivers. No lakes. The OE8RADIO dog is on the move in Carinthia, spreading the good word – at a solid 80 km/h, straight across the landscape, through forests,…

BandWacht is a new open-source tool for automatic band monitoring for radio amateurs. The software connects to any WebRX receiver on the internet, analyses the spectrum in real time, and notifies you immediately when activity…
