Also in GB2RS this week…

The DXpedition to Bangladesh will use two different callsigns during its 12 day operation. S21ZED will be used until the 22 March, with S21ZEE used for the last five days—the 23rd to the 27th. This is to comply with Bangladeshi regulations. The DXpedition team asks that stations not work the second call sign on the same bands or modes, if they already have worked the first.

Results for the 80 Metres Evening Counties Contest held on 21 February have now been published, see for the details. Congratulations to the winners. The leading stations outside Ireland were Dave, 2E0KVJ, SSB only, and Mike, G3VYI, mixed mode.

Some countries in the Northern Hemisphere that includes most of North America and some of the Caribbean, who observe Daylight Saving Time changed their clocks on 12 March at 2am. The UK will switch to British Summer Time on 26 March. Of course, most radio amateurs don’t change their UTC clocks anyway. Although you may have to change the settings on some computer programs.

A Near Vertical Incidence Skywave (NVIS) research paper is available for download. NVIS can be used for radio communication in a large area, around 200km radius, without any intermediate human-made infrastructure. It is therefore especially suited for disaster relief communication, communication in developing regions and applications where independence of local infrastructure is desired, such as military applications. It uses frequencies between around 3 and 10MHz. Entitled Radio Communication via Near Vertical Incidence Skywave Propagation: An Overview, it was written by Rosa Ma Alsina-Pagès and Ben A. Witvliet.
