Inspect each transverter's RF/IF, offset and validity flags for XVTR diagnosis¶

The Slice Troubleshooting dialog captures a snapshot of every transverter configured on your FLEX-8600 and displays its RF frequency, IF frequency, frequency offset, and validity flags. Use this when a transverter-based slice is misbehaving — wrong frequency, missing reception, or unexpected mode — and you need to confirm what the radio actually reports for each XVTR entry.

Before you start¶

AetherSDR must be connected to the radio. The dialog requires an active radio connection.
Any transverters you want to inspect must already be configured on the FLEX-8600.

Steps¶

Click Help > Slice Troubleshooting... to open the Slice Troubleshooting dialog.
Click the Issue Summary tab. Scan the bullet list for any XVTR validity warnings. The summary flags entries where is_valid is false or has_is_valid is false.
Click the JSON tab to see the full snapshot. Locate the transverter entries in the JSON. Each XVTR entry reports the following fields:
name — the label assigned to the transverter
index and order — position identifiers
rf_freq_mhz — the RF (over-the-air) frequency in MHz
if_freq_mhz — the IF (radio input) frequency in MHz
offset_mhz — the difference applied between IF and RF, in MHz
is_valid — whether the transverter entry is marked valid (Yes / No)
has_is_valid — whether the radio reported a validity flag at all (Yes / No)
rx_only — whether the entry is receive-only
max_power — maximum power in the XVTR entry
If you made changes to transverter settings after opening the dialog, click Refresh Snapshot to re-read the current state from the radio before drawing any conclusions.
To share the findings, click Copy Summary to copy the plain-language issue list to the clipboard, Copy JSON to copy the full JSON, or Export JSON... to save the JSON to a file.
Click Close when finished.

What each control does¶

Control	Kind	Behavior
`Issue Summary` tab	Tab	Plain-language bullet list of detected problems, including audio routing, DSP, control-device (MIDI) state, multi-client ownership, and XVTR validity issues.
`JSON` tab	Tab	Full JSON snapshot (schema version 3) containing slices, DAX channels, audio devices, client DSP, control devices, TX band settings, and all transverter entries with RF, IF, offset, and validity fields.
`Refresh Snapshot`	Button	Re-reads slice state into the snapshot.
`Copy Summary`	Button	Copies the issue summary to the clipboard.
`Copy JSON`	Button	Copies the full JSON snapshot to the clipboard.
`Export JSON...`	Button	Saves the full JSON snapshot to a file.
`Close`	Button	Closes the dialog.

Remote audio RX fields in the snapshot¶

v0.9.4 adds remote audio RX state to both the radio-level and per-slice sections of the Issue Summary and JSON snapshot. These fields help diagnose problems where AetherSDR has requested a remote audio stream from the radio but audio is not flowing.

Radio-level remote audio RX¶

In the Issue Summary, look for the line beginning Remote audio RX:. It reports the following:

Field	Meaning
`stream_id`	The stream identifier assigned by the radio, or `—` if none.
`stream_expected`	Whether AetherSDR expects this stream to exist (`Yes` / `No`).
`create_pending`	Whether a create request is still outstanding (`Yes` / `No`).
`status_seen`	Whether a status update for this stream has been received (`Yes` / `No`).
`owned_by_us`	Whether this client owns the stream (`Yes` / `No`).
`compression`	The compression type in use, or `—` if not reported.

A second line, Remote audio route note:, contains a plain-language note about the routing state, or — if none was generated.

Per-slice radio stream route¶

In the Issue Summary, look for the line beginning Radio stream route: remote_audio_rx. It reports the following:

Field	Meaning
`remote_audio_rx_stream_id`	The stream identifier for this slice's remote audio RX, or `—` if none.
`remote_audio_rx_expected`	Whether the stream is expected to exist.
`remote_audio_rx_create_pending`	Whether a create request is still outstanding.
`remote_audio_rx_remove_requested`	Whether a remove request has been sent but not yet confirmed.
`remote_audio_rx_status_seen`	Whether a status update for this stream has been received.
`remote_audio_rx_owned_by_us`	Whether this client owns the stream.

If remote_audio_rx_expected is true but remote_audio_rx_status_seen is false, the radio has not yet confirmed the stream. If create_pending is true for an extended period, the create request may not have reached the radio.

Tips¶

If has_is_valid is No for a transverter, the radio did not report a validity flag for that entry at all. This is distinct from is_valid being No, which means the radio reported the entry as explicitly invalid.
Click Refresh Snapshot after adjusting transverter settings in SmartSDR or on the radio before re-reading the values. The snapshot is not updated automatically.
The offset_mhz field should equal rf_freq_mhz minus if_freq_mhz. If it does not match your transverter configuration, that discrepancy is a likely cause of frequency errors on the slice.
When investigating missing audio, check the remote audio RX fields first. If owned_by_us is No and stream_expected is Yes, another client may have taken ownership of the stream.
