APRS-SCS Longitude Help

The Longitude Text Boxes
Here is where the user enters His APRS stations Longitude.
APRS-SCS defaults to 073 08 . 41 W
The 073 is the degrees of Longitude.
The 08.41 is the Decimal Minutes of Longitude.

The .41 when multiplied by 60 becomes 24.6 seconds.
So the above Longitude expressed in Degrees Minutes Seconds would be
073 08 24.6

To see what I am talking about lets say our Longitude in Degrees Minutes Seconds is
073 08 30 Which spelled out is 073 Degrees 08 Minutes 30 Seconds Longitude.
Since 30 Seconds is half a Minute. Then another way of spelling the above out
would be. 073 Degrees 08 and a Half Minutes. Expressed Mathematically
073 08.50 This is the same as taking the 30 seconds and dividing by 60.

What this is all leading up to is if you do not have your Longitude expressed in
Degrees Decimal Minutes then you have to convert your Longitude to
Degrees Decimal Minutes.

Another conversion example.
Lets say you have your Longitude expressed as.
073.1417 Decimal Degrees.
To convert to Degrees Decimal Minutes then take the .1417 and multiply by 60.
.1417 x 60 = 08.50 so your Longitude expressed in Degrees decimal Minutes
would be 073 08.50

Please make these conversions APRS-SCS only accepts Longitude in Degrees Decimal Minutes

What Is the "W" for?
The W stands for West. If you are West Of Greenwich England then Enter a W.
If you are East of Greenwich England then enter a E.
