I signal i have in the reciever is blue. not green.
I bought the satellite finder. when i connect the cables i recieved a conitnuos beep. Is this ok?. When i move the LNBF the gain increase. until 80.
In the reciver I select AMC4 but there no green signal. The blue one is 73.
the type is univeral. but in the trasponder what number i Select?

I assume you got the 60 deg and "south" angles by using an Az/El calculator, and those angles are possible for locations in Mexico, so I'll assume they are correct, however I have a suspicion that you may be confusing
installation of a single satellite fixed dish with a
motorized system, since the latter involves due south alignment, whereas the former only involves due south if by chance the sat you are looking for happens to be south. The directions you referenced are for a fixed single sat dish.
The 60 deg angle is probably the elevation of the satellite, and would represent the apparent direction of aim of a prime focus dish, but offset dishes actually look quite a bit above the apparent aim, typically 22-25 degrees higher. The markings on your dish mount may or may not be consistent with the correct angle you need, as some dishes mounts take the offset angle into account, some are just raw angles or possibly 90-the angle, and others indicate in terms of latitude, so you have to refer to the instructions relative to your specific dish to set the angle properly.
Since you have a signal meter, your best bet is to set the Azimuth as best you can, then experiment with changing the elevation. You mention a continuous tone. I would recommend turning the knob until you get a continuous low pitch tone, which you will get even if not aimed at a sat. Then change the aim until you hear the pitch increase when you are close to being aimed right. If you don't hear the change in pitch, then you are way off.
Once you have found "a" satellite in this way (ie it may not be the sat you think it is), then you can try to lock the signal with the receiver. Note, the receiver will NOT give you good signal/quality indication unless you have it set up to the proper transponder frequency and symbol rate. Very often the transponder lists that come installed on the receiver are out of date. If you can't find a transponder with the proper frequency and SR values, then you may have to create your own transponder with the proper values, or edit the existing entry.
Also, before you can get a lock, you need to insure that you have the satellite set up with the proper LNBF type and LO freqs.
Once you have the sat set up in the receiver, and are on a transponder that you know is current, only then can you get a lock. Basically you can ignore the signal strength as it will generally give indications even when not on a sat, and often only change slightly when on the sat. What you are looking for is a strong quality indication. If you get any quality indication at all, then you are close in your aim, and can make fine adjustments to get the best quality. If you got a good signal indication with your hand held signal meter, but are unable to get a lock on a known transponder, it may be that you are aimed at the wrong satellite. One thing you can try is to look in Lyngsat and find the closest nearby sats and see if you can lock on the freq/sr values for a known signal on those satellites. If you can, then you will know which direction you need to move your dish to find the sat you are looking for.
Anyway, bottom line is that you are probably not aimed at the satellite.
