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.
