Hello everyone. I just returned from my vacation and I have not been able to include logs and info in N&O. Don't worry, you didn't send me your findings in vain. I will include June's info in the July column, which should be a large one (I hope).

There is one thing that I'd like to mention though. I received very interesting info about the PIP (S30) via Jan Michalski from Krakow for which I thank him very much:

The users of this station are the Staff of the North-Caucasus Military District and it is part of "Network 800" of Russia 's MoD. The location is Rostov- na-Donu . It's tactical callsign is " Kolos " [Colossus]. The station is nicknamed " Kaplia " [Drop].

This month I have a very good jamming article for you written Mr I. Hallas , who has worked for a Soviet jamming station. Further some current items about jammers and an intelligence profile about Costa Rica . I hope that you will like it.

If you are interested in the subject you really should buy Rimantas Pleikys ' excellent book about Soviet jamming. You can order the book from

Jamming did not die with the collapse of the Soviet Union . Many other countries are still jamming "clandestine" stations from the opposition or broadcasts transmitted by the enemy.

During the last couple of months SW Radio Africa has suffered jamming from Zimbabwe on 4880, 11770, 12145 and 15145  kHz . The following item about this subject comes from BBC Monitoring research, April 26, via Radio Netherlands Media Network Blog .

"In March 2005, Paris-based organization Reporters Sans Frontieres reported, that the Media Monitoring Project Zimbabwe (MMPZ), a Harare-based independent watchdog, said the jamming of SW Radio Africa's broadcasts is being carried out from Thornhill airbase - located outside the southwestern town of Gweru , between Harare and Bulawayo - where the government has a transmission station. According to the International Broadcasting Bureau (IBB), a US federal government entity, the equipment being used for the jamming comes from China , which has close trade links with Zimbabwe , especially in the telecommunications domain."

Other jammers noted this month originate from China (9680, 11765 and 17525  kHz ), Vietnam (7125 kHz) and Iran (3875, 3930, 3970, 4370, 4610, 4860, 6425.5, 11575, 11624, 11629, 11630.2 and 11632.7 kHz)
