Top band DX-ing is real ham radio challenge. 160m is also referred as the "Gentleman's band"...

Hello all,
here I am posting some of latest news about VP6DX operation on Topband which I sumarized from their web. Originaly I arranged these informations ownself but Bill, W4ZV was faster so with thanks to him I am using over here his sumary report published originaly on Topband mailing list...
News #18- 2008 Feb 19

m contact made with opposite side of the planet
At Feb 18 Mon 1252z, the
Ducie Island 160m operator was called by, and
completed a contact with, A45XR in
Oman. A45XR is located less than 300 km from the antipode (exact opposite location on the planet) of Ducie Island essentially the most distant location from Ducie Island.

This contact took place during the late afternoon,
Oman time, 1 hour 10 minutes before sunset. At the time of the contact, the terminator was 2000 km from Oman, approaching from the east northeast.

All directions between antipodes are of equal distance. Over what path was this contact made?

At Ducie Island, A45XR's signals were heard best on the 305° beverage antenna. This suggests the signal path traveled over Japan, northern China, and Pakistan... exiting perpendicular from the twilight zone. It is possible a single E-skip hop between Oman and northeast Pakistan completed the path through the 2000 km daylight sector.

Congratulations to both operators!

Now that we have shown Ducie Island's topband operating team can contact even the farthest points on the planet, what's stopping you from trying a top band contact with VP6DX? If you think your antenna is inferior, or you are running limited transmitter power, don't give up! Look at the comments in the guestbook section of the website: lots of stations are now in the VP6DX logbook with very simple antennas and low heights -- event on top band.

So give every band and mode a try. We are waiting for your call!

We will also be listening on 160m for contacts on this path (or some variant). It would be a thrill to put long path contacts on top band in the log. Let's see how far we can push propagation!

Please submit any reception reports for unusual openings, including openings on other bands, via the VP6DX website.

North American 160m schedule
Most 160m operators in North America recognize that, when sun sets at Ducie Island (0300z), it is dark in North America and most of Europe.

Between this time and European sunrise is the only propagation window for contacts between Ducie Island and Europe. Many years will pass before another expedition arrives at Ducie Island at the bottom of the sunspot cycle. As a result, one of our expedition goals is to give as many stations in Europe and Asia a 160m contact with Ducie Island.

To accomplish this goal, North American stations (with much shorter path to Ducie) will need to wait.

Our top band operating team proposes that, on every evening, we will begin making contacts with North America no later than 08z. There is no need for North America top band operators to wait until their local sunrise to contact Ducie Island. 160m is staffed with an operator throughout the night.

As described elsewhere, the team has invested considerable work in an effective receiving antenna system to help us pull weak signals out from the static. Please give 160m a try! We are waiting for your call.
Thank You to Bill, W4ZV for editing the flash news.
