Open HPSDR,<div><br></div><div>Just some 'news' regarding the Jackson Labs GPSTCXO.</div><div><br></div><div>I have been able to calibrate Excalibur with the GPSTCXO with J1 removed from Excalibur (since the JL EVB outputs to a High-Z).</div>
<div><br></div><div>That seems to work OK. There are a few errors in the docs - like the module is 3.3V not 5V. The EVB has a 5V to 3.3V converter on it. Also there is a 1PPS output on the EVB (just some slight rework that isn't reflected in the docs nor the schematic).</div>
<div><br></div><div>Said has given me updated files, schematic plus gerbers for the EVB. I will update the Wiki later today with links. </div><div><br></div><div>Overall I think this looks like a good/great candidate solution. The console program provided by JL works fine plus I downloaded GPS CON and that works fine as well.</div>
<div><br></div><div>If anyone else is interested in acquiring a unit, which contains the module, antenna, EVB board, USB cable, and software CD - please let me know and I will e-mail you the information.</div><div><br></div>
