Audio Sample
29B6, nicknamed 'Контейнер' (Kontayner), is a Russian over the horizon radar. It is currently very active in Europe. The radar uses 150 antenna masts with data transmission systems, transmitters and receivers, a power station and control buildings. It is able to detect both high altitude and low altitude aircraft and missiles at very long ranges.

The first 29B6 radar installation is based at Kolkino radar station. The receiving antennas are located 8 km south-west from Kovylkino, Mordovia, Russia 53.9841°N 43.8427°E. The transmitters antennas are located 300 km from receiver, 5 km north from Gorodets town, Nizhegorodskaya oblast', Russia 56.69328°N 43.48625°E.

29B6 commonly uses 50 sweeps/sec (max range 3000 km), but it has been seen with 25 sweeps/sec (max range 6000 km) and 100 sweeps/sec (max range 1500 km). 29B6 uses Frequency Modulation On Pulse (FMOP), unique among OTHOver The Horizon (very long range) Radars since they tend to use Frequency Modulated Continuous Wave (FMCW).

29B6 Sounder[edit]

This is an Over The Horizon Radar Sounder signal from the Kontayner radar. It is used to check frequencies that are not in use. It commonly overlaps Amateur and broadcast shortwave bands.

This signal has ~13-14 kHzKiloHertz (kHz) 10^3 Hz of bandwidth and hops frequencies in an ascending manner. It starts from 9.2 MHzMegaHertz (MHz) 10^6 Hz, and moves up the band in various intervals until it gets to 19.745 MHzMegaHertz (MHz) 10^6 Hz. After this, it pauses for a while and then goes back to 9.2 MHzMegaHertz (MHz) 10^6 Hz to begin the sweep again.

Often times, the radar overlaps over broadcast and amateur bands with no regard, causing massive interference as reported here:
