I can pick it up real weak here in Heavener on an indoor scanner antenna. I would think you should be able to pick it up there. Are you programming it with the following info.
LTR System Van Buren LCN= 2,6,10,14,18 461.7125, 462.1375, 463.2375, 463.4875, 464.7375
IE 461.7125 must be on channel 2 of your bank, 462.1375 must be on channel 6, 463.2375 channel 10, 463.4875 channel 14 and 464.7375 on channel 18. Then the channel bank has to be set for LTR.
