Receive first
Listen to an available conversation or use the server audio test. Check device volume, the received-audio playback controls in Settings, and whether the selected room actually has activity.
Getting started
Set up your audio.
Make your first contact.
Begin with an approved account, a stable internet connection, a compatible browser and an available microphone. The secure application address is the same on phones and computers.
On the application sign-in page, choose Register new account. Administrator approval is required.
Android phone
- Open radio.digihamlink.com in a compatible browser, such as Chrome, using the full HTTPS address.
- Sign in after your account is approved. Allow the microphone permission when asked.
- Use Install app if available, or the browser’s install/add-to-home-screen option in a normal browsing window.
- Launch the installed app from its icon. Check the assigned-room connection status.
- Use a headset when practical, keep the screen awake while operating, and release PTT before changing apps.
Private/incognito browsing may not offer installation. Android system navigation and power management cannot be completely controlled by a web app.
Desktop computer
- Open the secure application address in a compatible browser.
- Connect a microphone or headset before starting a radio call. A computer without an audio input may fail to start a microphone-based session.
- Sign in and allow microphone access for the application’s domain.
- Check your operating system’s input selection and browser site permissions.
- Use Settings to adjust microphone gain and run the available audio tests. Return to Radio to operate PTT.
A wired or USB headset can reduce speaker feedback. Device labels and permission menus differ by operating system and browser.
A short audio check goes a long way.
Set your microphone level
Start with normal gain and speak naturally at a consistent distance. Reduce gain if the meter reaches the top or speech sounds distorted. A moving meter confirms local input, not end-to-end reception.
Test your voice privately
Use the available private echo test before a live conversation. End the test using its stop/disconnect control, then reconnect to normal radio operation as needed.
Good habits on a linked network.
- Listen for a clear channel before pressing PTT.
- Identify with your callsign and speak clearly.
- Release PTT after each transmission.
- Leave pauses so other operators can join.
- Stay within the configured 120-second transmission limit.
- Avoid a second audio path that creates a loop.
- Respect operating practices on every linked system.
- Use Reconnect audio with PTT released if your session fails.
If something does not work.
Cannot sign in?
Confirm approval, callsign and app password. Try a fresh normal-browser session if an old installed app is stale. Verify the secure application address resolves on your network.
Microphone not found?
Connect an input device, choose it in the operating system, and recheck browser microphone permissions. A successful login does not guarantee an audio device exists.
Connected but silent?
Check playback and device volume, then test server audio. Confirm room activity. If a bridge is involved, ask the owner to inspect its connection and audio path.
Start with your callsign
Your next conversation starts here.
Request an account, wait for approval, and explore the systems linked to your assigned room. Shared access does not require your own AllStar node credentials.
