Starting in August 2015, Dan Watson (Sync Channel Blog) started a project to develop a GPS board to "plug into" the Lucent KS-24361, RTFG-u REF-0 for standalone operation (without the REF-1 module) http://syncchannel.blogspot.com/2015/08/standalone-operation-of-lucent-ks-24361.html By October, he had a GPS board (Tria) that converted uBlox timing receiver output to the format desired by Lucent box (Motorola Oncore UT). http://syncchannel.blogspot.com/2015/10/tria-gps-success-in-ref-0.html His last post in November 2015 was about dongles. http://syncchannel.blogspot.com/2015/11/denuo-gps-hits-rev-b-dongles.html In 2016 he posted his later work on OSHPark, but stopped Blog posting about a year ago. Anyone have an update? He has commented in past that he is easily distracted. greg, w9gb Sent from iPad Air
