I'm experiencing an issue with AetherSDR, a Linux/macOS/Windows SDR client

for FlexRadio transceivers (https://github.com/aethersdr/AetherSDR).

My system:

• AetherSDR version: 26.5.3

• Qt version: 6.8.3

• OS: Windows

• Radio: FLEX-6400 fw 4.2.18.41174

Before writing the bug report, please read the AetherSDR project context at

https://raw.githubusercontent.com/aethersdr/AetherSDR/main/CLAUDE.md

for architecture overview, data flow, protocol details, and known issues.

Based on my description below, write a complete GitHub bug report.

Do NOT ask me follow-up questions — just write the best report you can

from what I've provided. Output it in one response, ready to paste.

Use GitHub-flavored Markdown formatting (headers, code blocks, bullet points).

When I start Aether, it finds and connects to my radio on my local LAN. The slice flag shows normally. However, no waterfall or panadapter displays, and Aether reports no panadapter data - waiting for radio stream

Developer Notes

(After reviewing the codebase, suggest which source files and functions

are most likely involved, what logging categories to enable in

Help → Support to capture diagnostic data, and any potential root causes

based on the code architecture. Reference specific file paths and line

numbers where possible.)
