[hpsdr] Excalibur & Gibraltar

[Steven Doyle]

Hi,

This months EPE Magazine also outlines a simple construction project for a 
GPS-Based 10Mhz frequency reference which would make an ideal pairing with 
Excalibur. Its based on the Garmin GPS-15L receiver module and can be built 
for arround £140. The PCBs are also avaliable from www.epemag3.com . The 
10MHz output is accurate to within 0.2Hz averaged over 30sec even more 
accurate when averaged over longer periods.

Features include

1Mhz & 10Mhz outputs
GPS 1Hz output
Phase error pulse output
LCD display for GPS information, typically the time.

cheers
