Airspy HF+ in Northampton (IO92NH), fixed gain (attenuator 0, LNA on, the radio's HF AGC off), recorded 2026-10-04 from 20:56 UTC for 238 s. About 0.7 % of samples were lost during recording in short bursts; the loop is cut from a stretch with none. Regenerate the clip with tools/iq-loop (see its README).
