How can I tell if my WAAS GPS is giving me a corrected fix? Look for a "D" in your Latitude/Longitude readout.
I found an old design online and I have found suppliers for all of the parts except for one component, the MC145157 PLL Frequency synth. is hard to find. Lansdale Semiconductor now produces the chip and I need to find a supplier. Or buy it off of eBay for $30.
Current Status: Found the MC145157 chip
