Enable an IQ stream for external SDR software

The DAX IQ applet lets you activate one or more of four IQ streams on your FLEX-8600 so that external SDR software can receive raw IQ data from the radio. Each stream can be independently enabled with its own sample rate.

Before you start

  • AetherSDR must be connected to a FLEX-8600 radio. IQ streams are not available without an active radio connection.
  • The DAX IQ applet is hidden by default. You must open it before you can enable a stream.

Steps

  1. Click the IQ tray button on the right sidebar to show the DAX IQ applet.
  2. In the row for the channel you want (IQ 1 through IQ 4), select a sample rate from the rate combo box. The default is 48k. Available rates are 24k, 48k, 96k, and 192k.
  3. Click the Off button in that channel's row. The button label changes to On and the button style changes to indicate the stream is active.
  4. Configure your external SDR software to connect to the corresponding DAX IQ channel.

What each control does

Control Default Valid values Persisted key
Rate combo box (IQ 1–4) 48k 24k (24000), 48k (48000), 96k (96000), 192k (192000) None
Off/On toggle (IQ 1–4) Off Off, On DaxIqEnabled1 – DaxIqEnabled4
Level meter (IQ 1–4) 0 0–100 (scaled from RMS Γ— 200) β€”

Tips

  • Your enable state is persisted across sessions. When you reconnect to the radio, AetherSDR waits briefly for the session to settle before re-enabling any streams that were active in the previous session.
  • The rate combo box syncs back to the radio-reported rate only when a stream is active and is not in a rate-settling state. If you select a rate while the stream is off and then enable it, your selection is applied to the freshly-created stream rather than being lost to the radio's 48k default.
  • When enabling a stream with a non-default rate, the radio briefly reports 48k while settling. The combo box avoids syncing to that transient value, preserving your intended selection.
  • The level meter resets to 0 whenever a stream is disabled, the stream is not bound to a pan (pan ID is empty or 0x0), or the radio disconnects.

Troubleshooting

  • The IQ tray button is not visible β€” The applet panel may be hidden. Go to View > Applet Panel to show it, then click the IQ tray button.
  • The button switches to On but no data arrives in external software β€” The stream request may have been sent before the radio was ready. Disable the stream by clicking On to return it to Off, wait a moment, then click Off again to re-enable it.
  • The rate combo reverts after enabling β€” If the stream is still in a rate-settling state, the combo box waits for the final rate. In rare cases where the radio overrides your selection after settling, the combo will sync to the radio's value.
  • Streams are not restored after reconnecting β€” This can happen if the applet loads after the radio connection is already complete. AetherSDR now checks for an already-connected radio at startup and restores persisted streams immediately.
