30 meter HF radar

Over the last 24 hours I have seen strong HF radar activity in the 30 meter band between 10.1MHz and 10.135MHz. I have seen this activity in the past but not for 24 hours straight. It produces straight horizontal lines at about 45 Hz spacing over the entire WSPR band. Some WSPR signals get through but not all. HF radar used for measuring ocean waves and currents is a real problem on some of the amateur HF bands. Are any others seeing this activity?
