QSO One (QS1)

Talk on AllStarLink from an Android phone or a PC — no Raspberry Pi, no radio interface, no Linux setup. This is how to get on, and how to reach Bob.

Call Bob — your node 50524 → his node 47371

  1. Open QSO One & sign in

    Confirm you're signed in as KA6ATN (top of the screen).

  2. Choose Node Mode

    If asked Node Mode vs WT Mode, pick Node Mode — that puts you on the air as your node 50524.

  3. Wait until 50524 is online

    Give it a few seconds until your node shows connected / registered (usually a green status).

  4. Tap Connect

    Find the ＋ / Connect button (sometimes a node-number box or a search icon) on the main screen.

  5. Enter Bob's node: 47371

    Type it and hit Connect. Use a normal connect (transceive) — not Monitor.

  6. Wait for the confirmation

    47371 appears in your connected list and you may hear "node 47371 connected." You're now linked into Bob's hub and the 146.61 repeater in Hot Springs.

  7. Talk

    Press and HOLD the big PTT / microphone button: "47371, this is KA6ATN, Paul — you there, Bob?" Release to listen.

  8. Hang up when done

    Tap 47371 → Disconnect (or the hang-up control) to drop the link.

If it won't connect: your node 50524 may not have finished registering (wait and retry), or Bob's node/radio isn't monitoring right then.

What QSO One is

QSO One (written QSO1 or QS1) is a free app that connects you to AllStarLink — and EchoLink, IAX Direct, DMR, System Fusion, M17 and P25 — from a phone or computer. It replaces the usual home-node hardware (a Raspberry Pi, a radio interface, and hours of Linux configuration) with an app you can be on the air with in about five minutes.

Get it: qso1.net — Google Play (Android 8+), Microsoft Store (Windows 10/11), iOS coming.

Node Mode
You go on the air as your own registered node (yours is 50524). Use this to connect 50524 out to other nodes — like Bob's 47371.
WT Mode
Web Transceiver — talk without operating a registered node. Simpler, but you're not putting node 50524 on the air.

The nodes

The AB5N nodes are Bob's (Hot Springs, AR); the KA6ATN-account nodes are yours (Cedar Creek, TX, plus Bob's shop devices you manage). Live from AllStarLink.

Connect commands (reference)

In QSO One you connect with the app's buttons. If you're ever on a radio node or a keypad instead, AllStarLink uses the same standard DTMF commands under the hood:

*3 47371Connect to 47371 in transceive (talk + listen) — the normal "call" connect. *2 47371Connect in monitor only (listen, don't transmit). *1 47371Disconnect from 47371. *70List the nodes you're currently connected to.
Always identify with your callsign (KA6ATN) when you key up — it's the rule, and it's how Bob knows it's you.
