Border Activity

In addition to DHS Border Patrol traffic, some listeners have reported activity that may be related to National Guard support of border enforcement.

From Eagle Pass, Texas comes a report of 391.0500 MHz, P25 with a NAC of N500. The report says the traffic is encrypted full time and not from Laughlin AFB.

Reports also mention some unknown type digital traffic in the 380-400 MHz bands that are not P-25, and rumored to be coming from Piedras Negras, Mexico.

UPDATE!
An alert reader pointed out that there is a wide-area TETRAPOL trunked system used by the Mexican Federal Police Forces, which may account for the unknown type digital traffic in the 390-400 MHz band.
