  How can I tell if my WAAS GPS is giving me a corrected fix?
    Look for a "D" in your Latitude/Longitude readout.

====== DGPS Beacon Receiver ======

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. [[http://www.lansdale.com/part_search.php?search=ML145157|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**
