[hpsdr] Excalibur & Gibraltar

[Joe Martin K5SO]

Alexander,

As one example of how one can use Excalibur to achieve extremely high  
frequency accuracy, I will not be using the on-board Excalibur TCXO  
but, instead, I will be using the 10 MHz output from an EFRATOM  
LPRO-101 Rb Vapor Frequency Standard module ($70-$100 eBay).  The  
LPRO-101 route is one way to avoid using GPS entirely.

But bear in mind that the on-board TCXO on Excalibur will be perfectly  
adequate for most users since the TCXO on Excalibur provides dramatic  
improvement over the Mercury and Penelope 10MHz TCXOs!  Either way (or  
some other way!), all indications so far are that Excalibur seems to  
work like a champ!

73, Joe K5SO
