An amateur-radio digital-modes operating app. Feed your radio's receive audio into your phone — through its microphone near the speaker, or a cable — and it decodes the open digital modes on a live waterfall. Type a message and it plays the tones back to your radio to transmit. It logs your contacts and exports them as ADIF, straight into Ham Logging or any other logger.
Fourteen: FT8, FT4 and JS8 for weak-signal work; a WSPR transmit beacon; the RTTY, PSK31, PSK63, PSK125, Olivia and Contestia keyboard modes; Hellschreiber's painted text; APRS and AX.25 packet at 1200 baud; and Messaging, which carries short text in any language. Every mode has its own on/off switch in Settings and a built-in tutorial. Picture modes such as SSTV live in our separate Ham Imaging app.
No — in Ham Signaling WSPR is a transmit-only beacon. It sends your callsign, grid and power on the 2-minute even-UTC slots; look your callsign up on wsprnet.org to see which stations heard you.
A valid amateur radio licence is required to transmit, and you operate within your own privileges. To receive you only need your radio's audio at the phone — acoustically or by cable. A cable gives cleaner audio and several decibels more on the weak-signal modes. Rig control (CAT) is optional.
Three things first. Sideband: the digital modes use USB; on LSB the tones are mirrored and nothing will ever decode. Frequency: FT8 on 20 m is 14.074 MHz. Clock: FT8 and FT4 need your phone's time within about a second of UTC — keep automatic time on. Each decode shows DT; when every station shows the same offset the app says so under the status line.
Yes. Settings → Your Details → Operating mode offers Manual (the default), Auto Hunt and Auto CQ. The automatic modes work one station at a time, carry the exchange to the end, log the contact, and stop rather than calling on and on. You remain the control operator.
Never. With rig control on, it reads your dial frequency and mode so logged contacts carry the true frequency — over your local network (Hamlib rigctld, Icom WLAN, Kenwood KNS, Elecraft K4, TCI or a serial-over-TCP bridge), over Bluetooth, or on Android over a USB cable. It does not touch your frequency, mode or split. The only thing it can write is PTT, and only if you choose CAT keying on a rigctld connection — the default is VOX or your own hand. Keep your radio's own time-out timer set.
Yes, while Keep decoding in background is on (the default). Android shows a notification while it listens; iPhone and iPad show the microphone indicator. Turn it off and the app stops listening when you leave it.
To hear your radio's receive audio — the digital-mode tones — and decode them on your phone. The audio is processed on the fly and never recorded, stored or sent anywhere.
Nowhere. They stay on your device. Unixeer runs no server, and the app makes no internet connections of its own. Your log leaves the phone only when you share the ADIF file yourself. See the Privacy Policy.
No — amateur radio is public. These modes are open, published protocols with no encryption, and anyone can decode your callsign and message.
