VLF: Changes in MSK usage

[Markus Vester <markusvester@aol.com>]

Dear VLF enthusiasts,

 

browsing through saved VLF-grabber screenshots, I noticed some recent changes of VLF MSK-band usage:

 

2010-06-24 06:00  20.27 kHz (ICV) QRT
2010-06-30 05:00  16.4 kHz (JXN) QRT
2010-07-05 07:05  18.3 kHz (HWU) QRT
2010-07-08 23:00  21.75 kHz (HWU) break for 6 hours
2010-07-10 06:00  22.1 kHz (GQD) switched from 100 bd to 200 bd
2010-07-10 10:00  19.58 kHz (GBZ) QRT

 

Thus within a couple of weeks, half of the European military signals have gone for good.

 

Perhaps there is less need for submarine communications in today's world... let's hope that the submarines themselves (along with all that other military hardware) may become obsolete in tomorrow's world!
