Various modes

Three new ENIGMA designators were issued this month; XT2 for the new pip and XWP for an Ocean Surface Radar; XSW for the Squeaky Wheel channel marker on 3828 kHz.

XT2

The mysterious second pip and 3-tone marker were on 7605.5 kHz for a couple of days and I completely lost them after 5 Feb. See also N&O #45.

XWP

XWP is not really an oddity or mystery signal. You can hear similar wideband pulses on many frequencies. They are transmitted by Ocean Surface Radars. The location of XWP is yet unknown. Possibly France.

The radar follows a fixed sked. At the time of writing I heard it on the following times and frequencies. The station stays on a frequency for a full hour and transmits in 3 slots: h00-h19, h20-h39, h40-h59.

0700 UTC	6818 kHz
0800 UTC	6900 kHz
0900 UTC	9390 kHz
1000 UTC	9250 kHz
