I recently updated the db and wiki articles with information about several LTR systems in the DC area obtained via LTR Analyzer. Here's a summary and some additional information. Please submit updates.
Loudoun County Public Schools (reported to be LTR-Net but looks like it reports valid LTR Standard data in addition to the "extra" data):
451.9375 reports LCN=4, Area=0, Free=10/14
463.7875 reports LCN=13, Area=0
452.7375 reports LCN=14, Area=0
463.9375 reports LCN=18, Area=0, Free=13/19/20, talkgroups 0-18-005 and 0-18-085 heard
Some as yet unidentified LTRs:
451.875 reports LCN=20, Area=0
452.3875 reports LCN=5, Area=0, Free=1/3 -- talkgroup 0-05-011, very weak from Rockville/Gaithersburg
463.7125 reports LCN=2, Area=0, Free=1 -- very weak from Rockville/Gaithersburg
496.1625 reports LCN=4, Area=0
("Free" indicates the LCNs that the channel is advertising as available
when the channel is busy.)
