XWP - HF ocean surface radar

The radar is still using the same set of frequencies but a different schedule than last year. I have followed it during a couple of evenings and found the following:

1700 UTC : 8034 kHz  
1900 UTC : 6818//6900 kHz
2000 UTC : 6900 kHz. Moved to 8034 kHz at 2002 UTC (20-6)
2002 UTC : 8034 kHz  
2100 UTC : 6818//9250 kHz
2200 UTC : 8158//9250 kHz
2300 UTC : 8158//9250 kHz

Jammers

Iran : 3875, 3880, 3915, 3940, 4250, 4375, 7490 kHz
Cuba : 6030, 7365, 7405 and harmonics on 12060, 14670, 14810, 18090 and 22095 kHz
China : I received a note from Brendan who writes that he heard the Chinese Music Jammer on several frequencies that are not in the list that was published in N&O #52, namely 7185, 9780, 11665, 11925, 11950, 12090, 13715 and 15530 kHz.
Ukraine : 100.9 MHz

 

Tom Norris from Tennessee supplied some info about the Havana Gurgler.

"Radio Marti - a US sponsored politically motivated anti-Castro station transmits on 6030 and 7365 kHz on the shortwave broadcast bands. Cuba regularly jams these transmissions with a jamming device that has a signal similar to gurgling water, thus the noise has come to be known the Havana Gurgle. Trouble with these jammers is they are very "dirty" and the harmonics can be heard at very strong levels on several frequencies.
The jammer for 6030 kHz can be heard on 12060, 18090 regularly in the US. The jammer for 7365 can be heard regularly on 14670 and rarely on 22095. These frequencies are "nominal" since it is said that Cuba has many locations for its jamming equipment and I'm sure all the jammers are not exactly on frequency - an example is the harmonic for 6030 can be heard on 18090, but also on 18086."

Tom has sent me a couple of Gurgle samples. You can find them on the N&O website.
