TROUBLESHOOTING WORKSHOP
No reception?
From a silent speaker to an overloaded SDR: work through the receiving chain.
For analogue voice and SDR reception. Use a known station that is actually active. An empty channel alone does not prove a fault.
Compare antenna and feed line
If several suitable references are missing, compare the shared receiving path.
- Switch the device off before checking connections. Inspect connectors, adapters and cable for visible damage; check the selected antenna input and antenna band.
- Compare with a known suitable antenna or a short known working feed line. Change location and orientation separately, not everything at once.
What to look for next
Note which individual change improves reception. Without a reference, no particular component can be declared faulty.
