ARLA/CLUSTER: Como detetar e caraterizar Radares OTH nas bandas em HF

[João Costa > CT1FBF]

Looking at an HF OTH radar

*Daniel Estévez EA4GPZ* was inspired by *Balint Seeber VK2FUNK*'s talk in
GRCon16 to learn more about HF Over The Horizon Radars

Most amateur operators are familiar with over-the-horizon radars in the HF
bands. They sometimes pop up in the Amateur bands, rendering several tens
of kilohertzs unusable. Here I look at a typical OTH radar, presumably of
Russian origin. It was recorded at my station around 20:00UTC on 8 December
at a frequency around 6860kHz. This radar sometimes appears inside the 40m
Amateur band as well.
