Garmin GPS 18x LVC 010-00321-36 for your's own high-precision time server
5 January 2014
Summary: Highlight the Garmin model with the index 00321-36. This "36" option has a separate output line with a pulse-per-second logic-level output with a rising edge aligned to within 1 microsecond of UTC time. The GPS satellite signals are based off of onboard atomic clocks which are in turn synchronized to ground based atomic clocks that are the primary references for timekeeping. They represent the passage of time at the earth's geoid.
Summary: This thing is perfect for use with Uniden's Home Patrol-1 scanner. Use a null modem cable (also bought from Ebay) and a Uniden BCD396 or 996 X or XT programming cable and you're all set for position contriolled scanning as you drive.
