May ALE Hits #4 (8050 & 9025 kHz)

The 8050 Connection:

8050.0 kHz USB has at least three different agencies using it, and probably more. Interoperability? Coincidence?

DKB - - - -- - - US JSOC, Ft. Bragg, NC, sounding
FC8 - - - - - - - FEMA Region 8, Denver, CO, sounding
HUNGRIA2 - Mexican Army, clg HUNGRIA ("Hungary")
PASTOR - - - Mexican Army, wkg CANDELA ("Candle")


The 9025 Connection:

9025 kHz USB is a primary US Air Force SCOPE Command radio system autopatching frequency. It's mostly USAF, but other DoD users come up there, and at least one agency in Mexico also uses it.

Suspected Mexican Military ALE Frequencies

Not all are confirmed, but most are. There are a lot of them. Some are more active than others. There may be other frequencies, higher or lower, that no one's heard.

6200 and 8050 are used in the US by FEMA and the National Guard respectively. It is not known if their presence on the list is due to listener confusion.

9025 is also a busy US Air Force ALE frequency. Dialing instructions for phone patches are passed in the AMD field. Strange though it seems, Mexican activity has also been repeatedly confirmed here.

All kHz, USB unless noted.

PEMEX Adds ALE Frequencies

PEMEX, Petroleos Mexicanos, the Mexican national oil company, has finally put up more Automatic Link Establishment (ALE) frequencies to go with the original three. Three freqs isn't much of an ALE net, but now it starts to look like the real thing.

These are the frequencies that various people have reported. The ones I can verify personally have a * :

2182.0 * (1)
3700.0 *
4078.8 *
4487.5
4900.0 * (2)
7450.0 *
8291.1
8242.9
9265.0
11095.0 *

Notes:
(1) This is an international maritime calling and distress frequency, and it is doubtful if Pemex is allowed to sound there for any length of time.

(2) 4900 has so far only had Mexican military here, but I'm keeping it in the scan because others have heard Pemex.

PEMEX ALE Net

11095.0 kHz ALE is very busy with soundings from Pemex (Mexican oil company) facilities in the Gulf of Mexico. In the past few minutes, calls copied include ATASTA1, AKALJ2, REBOM1, ATASTA2, REBOM2, AKALN1, AKALN2, and AKALL1. All are soundings, all passing the first three characters in the TWS word, and the rest in DATA.

Oddly, the only other frequency being reported for this net is on 2182 kHz, the international USB distress and calling frequency, where it is stepping on other traffic.
