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 5

What do you observe on the active signal?

Use the S-meter, spectrum and audio together where available. This observation narrows the search; it does not measure the cause.

Little or no signal Strong but distorted or full of spurious signals Broad noise or regularly spaced interference
