Hi
Im having trouble getting right info from my PMB 248 GPS antenna. It only ticks each second and change each second.
This is the program I'm using:
It belongs to George Lejnine.
When I debug the info I get from N, NN, W and WW. I only get garbage data. It ticks like the clock and counts to 60 then it starts over.
