How do I discern Maidenhead Locator from GPS lat long info.

[tasmod]

It's between DEC4 in gps string and Aint in locator code.

I can get the display right but not the locator using DEC4 in the gps string and DIGs in the display LCDOUT.

I can get the locator right but not the position display if I just use latsecs as the variable in the gps input string.

Not knowing how Aint works I'm stumped now.

EDIT:

Just walked the property with the phone. Wow, those squares are small. I get LG, LH, KG, KH and guess where the crossover is, yes, right around the room where the unit is. I think I'll stick to DEC2 for now
