🔗 Ham radio over the internet

Some of these you can try in the next five minutes, with no licence and nothing installed. Others put you on the air worldwide and want proof of your licence first. Here is what each one actually asks of you.

👂 Listen now — no licence, nothing to install

Receive only. You cannot transmit through any of these, which is exactly why anyone can use them.

WebSDR

Listen only

Tune a real receiver in the Netherlands from your browser and hear HF as it sounds there right now. Several people listen on different frequencies at once.

You need:
Nothing. No licence, no account, no install.
Use it via:
Web browser
Worth knowing:
You are hearing what that antenna hears, not what is audible from India.
Open WebSDR ↗ Checked at websdr.ewi.utwente.nl

KiwiSDR network

Listen only

Hundreds of public receivers around the world, each openable in a browser. Pick one near a station you want to hear.

You need:
Nothing.
Use it via:
Web browser
Worth knowing:
Receivers are run by individuals, so any one of them may be busy or off.
Open KiwiSDR network ↗ Checked at kiwisdr.com/public

BrandMeister Hoseline

Listen only

Listen to DMR talkgroups live in a browser as people key up. Useful for hearing what a talkgroup is actually like before you join it.

You need:
Nothing to listen.
Use it via:
Web browser, Phone app
Worth knowing:
Listening only - Hoseline has no transmit side.

🎙️ Talk — licensed operators

Each of these wants proof of your licence before your first transmission. That step takes time, so start it before the net you want to join, not during it.

EchoLink

Phone app Computer software Web browser Radio or hotspot

Talk through a repeater somewhere else in the world, from a computer, a phone, or by sending DTMF from your own radio through a local node.

You need:
A licence, validated by EchoLink before you can transmit. Free.
Reaches:
EchoLink nodes and conferences worldwide
Worth knowing:
EchoLink publishes no turnaround time for validation, so start it before the net you want to join rather than during it. Anyone quoting you a number of days is guessing.

Peanut

Phone app Computer software

Digital voice rooms over the internet with no radio at all. Good for hearing D-STAR, Fusion and DMR without buying a set for each.

You need:
A licence and a Peanut code, requested at register.peanut.network. Free; that page says the request can take up to 48 hours.
Reaches:
D-STAR, Fusion (YSF), DMR, NXDN and M17 rooms, plus rooms for SSTV images
Worth knowing:
Android, Windows, macOS and Linux. The author’s own page still carries a November 2024 note saying there is no iPhone or iPad version and a beta is in progress - check before planning around an iPhone.

AllStarLink

Radio or hotspot Web browser

Links whole repeaters and hotspots to each other over the internet. You normally reach it through a radio rather than an app.

You need:
A licence, uploaded during registration, and a node - typically a Raspberry Pi or a ready-made appliance.
Reaches:
AllStarLink nodes; also reachable from EchoLink and other VoIP clients
Worth knowing:
The most work of anything here: it expects you to run a node, not just install an app.

Whichever you pick, operate within your licence conditions — see the VU band plan.

Why there are no node numbers here

EchoLink's directory needs a validated account, so there is no public source this site can read. A node number is the thing you key into a radio, so a guessed one would send you to whatever station happens to hold it. Look the number up in the EchoLink app or at echolink.org, searching for the callsign above.

The same goes for whether a node is on the air right now. This page cannot know, so it does not say.

9999*ECHOTEST*. The network's own test server. Connect, speak, and it plays your audio back so you can hear how you sound before joining a net. It is the one number worth memorising, and the only one on this page, because it is published and the same for everyone.

Where to start

Not licensed yet

Open a WebSDR and listen to 40m in the evening. Nothing to install, nothing to break. Then see the licence steps.

Licensed, no HF rig

EchoLink on a phone gets you into nets on other continents through a local node. Get validated first — that is the slow part.

Curious about digital voice

Peanut lets you hear D-STAR, Fusion and DMR rooms without buying a radio for each one — a cheaper way to find out which you like.
