5745 Spanish comms

[brandon]

Spanish language comms on 5745 kHz USB this evening around 0300z. A few of the stations were quite strong here.
The players also have roger beeps each time they key up. Traffic still ongoing as I am posting this.

Logged some id's as "Romeo Alpha" and "Romeo Delta"

They shifted to 5740 kHz.

More listening to 5740kHz I'm wondering if perhaps this could be Mexican Navy.
Papa Oscar 152 calling Romeo Delta multiple times. I also heard reference to Papa Oscar 151
I just Google and found this info from Wikipedia
PO 151 ARM Durango
PO 152 ARM Sonora

Durango class patrol vessel - Wikipedia, the free encyclopedia
The Durango-class is an Offshore Patrol Vessel class in the Mexican Navy. This class of ship features stealth characteristics. The entire class was designed and built in Mexico. These oceanic patrol vessels are used mainly in drug interdiction and coastline protection.

If this is really what we are monitoring then what a thrilling catch!

I listened to a bunch of traffic between the 2 frequencies. Here's a couple audio recordings.

To me first clip sounds like Papa Oscar 152 calling Romeo Lima Segundo

Here is a longer audio sample. Since I don't speak Spanish, I'll leave this one to the experts
