In this way with a small printed paper in the pocket and the low cost HT anyone could define his position in the APRS system (of course if he knows his position and if there is APRStt infrastructure in his area...)<br><br>In the attached file (PNG picture) you can find my proposal for a simple conversion table<br><br>the result is that you add a group of 3 number-digits for each 2 letters of the grid<br><br>eg. KM = 502, KM17 = 50217, KM17uw = 50217902, KM17uw48 = 5021790248<br><br>based on the fact that my proposal uses only the 0-9 digits and not the *,#,A-D this makes it compatible with the APRStt format.<br><br>The conversion table was designed in a way that the conversion from the number to ascii will be very easy (even for 8-bit microcontrollers) and will not require usage of memory lookup tables.<br><br>Below is a sample code (in basic style) that will convert the 3-digit number into the Grid Square letter characters (e.g. for i=502 then Chr(C1) becomes "K" and Chr(C2) becomes "M")<br><br>----------------------------<br><br>'example I=536 will print "NQ"<br><br>Dim I, X, CO1, CO2, C1, C2 As Integer<br>I = 536<br>If (I >= 100 And I < 340) Then<br> CO1 = 10: CO2 = 65<br>ElseIf (I >= 400 And I < 640) Then<br> CO1 = 40: CO2 = 75<br>ElseIf (I >= 700 And I < 940) Then<br> CO1 = 70: CO2 = 85<br>End If<br>X = Int(I / 10)<br>C1 = 65 + X - CO1<br>If C1 < 65 Or C1 > 88 Then End 'ERROR i is outside limits<br>C2 = I - X * 10 + CO2<br>If C2 < 65 Or C2 > 88 Then End 'ERROR i is outside limits<br>MsgBox Chr(C1) & Chr(C2) <br><br>--------------------------<br><br>In the above sample code the C1 and C2 are integers that contain the ASCII value of the 2 characters.....
