IARU report OTH Radar systems on amateur bands The Cyprus radar systems were active on 10 and 21 MHz. Turkish OTH radar systems (50 pps, 20 kHz wide) were abusing 14 and 21 MHz. On 21 MHz the radars were splattering over +/- 30 kHz. Locations: Area of Canakkale and East- Turkey. Spanish military was testing the new Spanish OTH Radar on 14184 and 14303 kHz, often with th 66.66 pps. Russian OTH Radar Kaliningrad on 7054 kHz (38.47 pps - 4 kHz wide) on Sep. 28 .
