Welcome to My Website

I use these pages to collect together various bits and pieces about my ham radio interests, and to share information you might need like QSL details. I also publish my logs here so that you can check if you have ‘worked’ my callsign. My US call is N3QI.

"DX Lite" mobile phone cluster interface · 19 March 2009 by Michael Wells

I often access the cluster from a Treo PDA over GPRS. Most of the good DX web sites are advertising and displaying graphics, with filtering tools etc. While this is excellent for regular internet use, it’s not really desirable on a phone interface. Also, page refreshing is often a hinderance!

I have written a very light DX Cluster web site with these problems in mind.

To get DXCC and IOTA information in an extra column, use:

http://dxlite.g7vjr.org/?full=1

To get the output in XML:

http://dxlite.g7vjr.org/?xml=1

To search in a particular band:

http://dxlite.g7vjr.org/?band=160

or for 6m up: http://dxlite.g7vjr.org/?band=vhf

To search for a particular callsign (or prefix):

http://dxlite.g7vjr.org/?dx=N8S

To specify how many results (default 50, maximum 500):

http://dxlite.g7vjr.org/?limit=125

To have the page automatically reload every 30 seconds, use refresh=1:

http://dxlite.g7vjr.org/?refresh=1

To see spots by, and about, a specific call, use spotter:

http://dxlite.g7vjr.org/?spotter=g7vjr

If you find the dx= flag too broad (because it uses sub-strings) you can try dxexact instead, eg:

http://dxlite.g7vjr.org/?dxexact=N1A

To filter by the spotter (eg. “spots from stations beginning with G”) use:

http://dxlite.g7vjr.org/?filter=G&dx=VK9

You can use most these arguments together, for example:

http://dxlite.g7vjr.org/?full=1&band=160&dx=n8s&refresh=1

Thanks to Marios 5B4WN for the idea of the XML feed (and for the XSL sheet), and also for helping with DXCC country look ups from callsigns (not as easy at it looks, thanks Marios!).

If anyone else finds this sort of thing useful, it would be nice to hear from you in advance if you plan to mine the XML version. Have a look here to see what Marios has done with Google Maps from DXLite – it’s a really interesting concept.

To prevent abuse, DXLite rejects IP addresses making too many requests. Also, DXLite silently filters out cluster spam, self-spotting and QSL news “spots”. I do this to improve the relevance of DXLite information. I devised the rules based on 2 million historical records. I prefer not to publish the rules, but will respond to emails on this topic from regular DXLite users.

I hope you find DXLite as useful as I do, and thanks for your interest in this tool. 73 – Michael G7VJR.
