I am currently searching for Deming and Lordsburg New Mexico Border Patrol Frequencies.Before their P25 upgrade they used 165.900, 168.875, 163.675. I have searched 160.000-174.000 with no luck. Complete silence. I can hear Santa Teresa, Las Cruces, Fabens TX, El Paso TX, and Ysleta Border Patrol perfect. The Bootheel of NM is silent? Are they in a different band. Any help is greatly appreciated and I will be more than happy to share the digital frequencies I have found. Thanks in advance.
