Excalibur 10 MHz Reference Injector card

About Excalibur

Excalibur is a small accessory card for the Atlas bus that enables the use of an external 10 MHz frequency reference for locking the frequency of an HPSDR radio to the same accuracy of the standard, or GPS disciplined oscillator. It also provides an optional TCXO frequency reference for the HPSDR, that is much better than the on board 10 MHz oscillators, although not as good as an external standard or GPS-DO. This board is much simpler than the main HPSDR cards, so I expect that they would be offered as either bare boards, or as kits as was Atlas. This card uses the larger 1206 surface mount parts for easier manual assembly.

The project leader for Excalibur is Graham, KE9H.
