DX Monitor Analysis of the 3Y0X DXpedition

DX Monitor Analysis of the 3Y0X DXpedition

From February 8 to 19, 2006, a group of 21 hams led by K0IR and K4UEE operated from the rare DXCC Country, Peter 1 Island and made an astounding 87,034 QSOs. The first real spot to appear was made by K4TD at 0552z on February 8 and he was also the first station in the log. The last real spot was made by EA5ASQ, just 4 minutes before they went QRT.

DX Monitor is a Windows program which monitors the DX announcements available on the internet at DX Summit, HB9DRV and connections to one or more local and international DX Cluster Telnet Servers. Collected DX spots can be plotted, sorted and tabulated in many ways. DX Monitor now plots DX Spots on Google Earth on request or in real time as the spots arrive.

The activity from 3Y0X by band by time of day in these scatter plots clearly shows that this was a 24/7 operation. [History Window: Plot - Activity by Day].

Spots by band by time of day

During the time they were operating, DX Monitor showed over 12,000 spots of 3Y0X by amateurs in 127 different countries. That is about 9% of the 132,000 spots for the month and almost 17% of the 71,000 spots that were posted while they were on the air. The total spots during the period of the DXpedition was more than the usual activity in February, which indicates that the DXpedition caused other DX stations to be active and on the air.
