Hi John, an interesting thought - I hadn't even noticed that! Considering in Preferences - Home Station Data; latitude and longitude have to be entered in decimal format, with Negative details for locations west of Greenwich; very surprising really. It is actually quite easy to work out using the Windows calculator - take 50 degrees 45 minutes 30 seconds - well the 50 stays as 50, then multiply the 45 by 60 to calculate the number of seconds, then add the 30 secs, divide the total by 3600 (total no. of seconds in 1 degree). Example 50 degrees 45' 30" :- 45x60 =2700, add the 30 = 2730, divide by 3600 = 0.75833333, stick the 50 back in front and you've got 50.758333333, doubtless there will be a conversion program somewhere on'tnet, or it could be done very easily with Excel (but don't ask me how! - the maths I can cope with, but not spreadsheets!!).
