Retry Discovery When No Radios Appear¶
When AetherSDR's local discovery finds no radios, the "No local radios found yet" callout appears in place of the radio list. This page explains how to trigger a fresh discovery scan and what to try if the list stays empty.
Before you start¶
- AetherSDR is open and showing the "Connect to a Radio" panel. If it is not visible, go to
Settings > Connect to Radio.... - Your FLEX-8600 is powered on and connected to the same LAN as your computer.
Steps¶
- In the "Connect to a Radio" panel, confirm that Local is the selected mode. If it is not, click Local.
- If the "No local radios found yet" callout is visible, click Retry Discovery.
- Wait a few seconds for AetherSDR to listen for discovery packets. If your radio is found, it appears in the Available radios list.
- Select your radio in the Available radios list, then click Connect Selected Radio.
What each control does¶
| Control | Kind | Behavior |
|---|---|---|
| Local | Mode button | Switches to local LAN discovery mode. |
| SmartLink | Mode button | Switches to SmartLink remote connection mode. |
| Manual | Mode button | Switches to manual IP connection mode. |
| No local radios found yet | Indicator | Shown when discovery returns no results. Replaces the radio list. |
| Retry Discovery | Button | Re-runs the LAN discovery scan immediately. |
| Connect Selected Radio | Button | Connects to the radio highlighted in the Available radios list. |
| Connect by IP | Button | Shortcut to the Manual connection mode. |
| Remote with SmartLink | Button | Shortcut to the SmartLink connection mode. |
| Open Network Diagnostics | Button | Opens the network diagnostics display to inspect connectivity. |
| Radio IP address | Combo box (editable) | Enter or select the IP address to use for a manual connection. The drop-down lists up to three recently used addresses. Saved as ManualRadioIp; recent entries are stored under RecentConnectByIpAddresses. |
| Connect to last radio on start up | Checkbox | When checked, AetherSDR auto-connects to the last used radio on startup and on broadcast-discovery / routed-radio probe. When unchecked, the connection dialog opens and the user must pick a radio manually each session. Saved as AutoConnectToLastRadio. Defaults to checked. |
Tips¶
- The "No local radios found yet" callout also shows while discovery is still in progress immediately after launch. Wait a few seconds before concluding the radio is unreachable.
- If the radio and computer are on different subnets or you are using a VPN, mDNS discovery packets will not cross the network boundary. Click Connect by IP instead and enter the radio's IP address directly.
- Guest Wi-Fi networks commonly block device-to-device traffic. If you are on Wi-Fi, check whether your access point enforces client isolation.
- The Radio IP address field retains up to three recently used addresses. Open the drop-down to reuse a previous address without retyping it.
- If you share the computer with other operators or prefer to choose a radio explicitly each session, uncheck Connect to last radio on start up. AetherSDR will open the connection dialog on every launch instead of connecting automatically.
Troubleshooting¶
- Retry Discovery does nothing and the list stays empty — The radio may be on a different subnet, behind a VPN, or blocked by a host firewall. Click Connect by IP and enter the radio's IP address manually, or click Open Network Diagnostics for more detail.
- Radio appears briefly then disappears — Network instability or a firewall dropping mDNS traffic intermittently. Check your firewall rules and retry. If the problem persists, use Connect by IP for a stable connection.
- Open Network Diagnostics shows no useful information — Go to
Settings > Network...to open the full network diagnostics display. - AetherSDR connects to the wrong radio on startup — Uncheck Connect to last radio on start up so the connection dialog opens on launch, then select the intended radio manually.
