I was playing around in the RSGB's 432MHz activity contest last night (enjoyable but no-one terribly distant worked) when I saw a tweet go by, from AI4RI, I think, asking if anyone knew any tools for mapping the grid squares that they've worked at VHF.I use the Winlog32 logging program
, written by Colin, G0CUZ which has some grid mapping capability built in - although it does not overlay the squares onto a map.Another tweet from AI4RI quickly appeared saying that he'd found the WorkedGrids software from VE2ZAZ
. I'd seen it mentioned before but not tried it. The software installed quickly and I was able to point it at an ADIF file that Winlog32 had created. If you have a logging program that keeps the log in plain text, ADIF or Cabrillo then you can use WorkedGrids to scan the file automatically and plot your grids on a map. Winlog32 keeps the log in an Access database so I had to create an ADIF export and point WorkedGrids at that.WorkedGrids setup allows you to select which bands you are interested in, I chose 50,70,144 and 432MHz, but you could just as easily select other bands. Having done that, a basic but effective map was displayed, showing the grid squares I'd worked on each band.I seem to remember that DX Atlas
by Afreet Software - as used by the FSDXA's 3B9C expedition some years ago has a similar capability.
