Radio‐Quiet Ionosonde Observations for Monitoring Absorption in the HF Band
Radio Science, Volume 61, Issue 8, August 2026.Abstract This work presents a technique to monitor ionospheric absorption in the HF radio band using ionosondes. For this purpose, the ionosondes were run in a radio‐silent mode, recording not reflections of their own emitted signals but oblique signals from transmitters of opportunity.
