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.

CHECK 6

Can you receive another known station?

Compare within the relevant frequency range and at roughly the same time. A distant signal on another band is not an equivalent reference.

Yes, only the first signal is missing No, or no reliable reference
