AllStar Node 573470
Node 573470 is the UHDARC master AllStar linking node. This is the primary “hub” where RF sites and supported digital gateways converge so the system can operate as one network.
System Overview
UHDARC uses AllStar as the backbone to link radio sites and bridge supported gateways into one consistent network. The master node (573470) provides a stable anchor point so RF, VoIP users, and approved digital mode paths can meet in one place.
| Node ID | 573470 (UHDARC Master / Hub) |
|---|---|
| Role | Primary linking core for UHDARC. Routes audio between connected users, RF links, and configured gateways. |
| Who can connect | Public access for amateur radio operators. Abuse, interference, or disruption may be blocked to protect the system. |
| Digital ingress example | AmComm DMR node 313040 (when bridged/configured) can provide a path into the UHDARC AllStar hub. See Talkgroups for current access details. |
| Best practice | Pause 1–2 seconds before speaking so linking paths open cleanly and you don’t clip the first words. |

Think of 573470 as the “dispatch center” for the audio network: RF users, AllStar users, and configured gateways all route through a shared hub so UHDARC behaves like a single linked system.
- Consistent connection point for members and visitors.
- Controlled routing between RF and approved IP paths.
- Ability to segment or prioritize links during nets/emergencies.
- Cleaner audio handling than daisy-chaining random links.
- Not a “free-for-all chatroom” — it’s a shared radio resource.
- Not a replacement for proper on-air etiquette and identification.
- Not intended for prohibited content or intentional disruption.
How to Connect
From your AllStar node/app, connect to 573470.
Wait 1–2 seconds before speaking. This prevents clipped audio on linked paths.
Give your callsign, keep overs reasonable, and leave room for others.
- Connect to node 573470.
- Identify properly and keep transmissions concise.
- Give a short pause between overs so others can break in.
- If you key up, identify (no kerchunking).
- DMR access may be provided via configured gateway routing.
- Example: AmComm DMR node 313040.
- Bridging is dependent on current configuration and status.
- Use the Talkgroups page for current DMR specifics.
What is AllStar
AllStar (AllStarLink) is a VoIP-based linking platform used by amateur radio operators to connect repeaters, remote bases, and simplex nodes over IP. It is commonly built around Asterisk and enables flexible linking, routing, and automation between nodes.
UHDARC uses AllStar as the network backbone because it is stable, proven, and supports clean linking between multiple sites.

Operating Etiquette & Network Protection
- Pause before talking to avoid clipped audio.
- Identify with your callsign, and keep it clean and professional.
- Leave space between transmissions for others to break in.
- Avoid long continuous overs; share the resource.
- Links and gateways may be active/inactive due to maintenance or configuration changes.
- During nets or incidents, follow net control direction.
- Abuse or intentional interference may result in temporary or permanent blocks as needed.
- This system is run by volunteers; treat it like shared infrastructure.
If people say you’re “clipping,” it’s almost always because the first second of audio is getting cut off. Key up, pause, then talk. It sounds dramatically better across linked systems.
