Fix missing hardware or an empty result
Check the receiver before interpreting a quiet spectrum.
No receiver: check OTG support, the data cable, power and the USB prompt. Interface busy: close the other app holding the dongle. A permission denial or disconnected cable is not evidence that no signal exists.
Flat spectrum or silence: check the antenna, frequency units, tuning mode, volume and whether a known reference signal is available locally. A strong signal can overload a receiver; an unsuitable antenna can miss one.
If reception stops during a recording, inspect the completion or error message and verify the saved file before sharing it. For a storage error, keep the original data and free space without deleting the affected collection.
