Over-the-Horizon radar station

Via Southgate: IARUMS newsletter – Over The Horizon Radars

IARU Monitoring System (IARUMS) Region 1 newsletter says in July, like every month for many years, Over The Horizon Radars were the most numerous transmissions causing interference to our HF amateur radio bands

The newsletter says:

The front runner was the RUS Contayner (BW = 12K0E; 40 sps), received in all bands from 40 to 12 m. The CHN OTHRs sending short bursts (BW = 10K0E; 41.7, 50, 66.7 and 83.3 sps) were also very active and were mostly observed on the 20 m and 15 m bands.
