There is something that I fail to understand on that site....<br>
Selecting as antenna Madrid 54, sending and receiving from MMS3, it
is possible to see what follows :<br>

<br>
Now, a power received of 3.81 x 10^-55 kW, translates (unless I made
an error) to about -484 dBm....<br>
I don't know what the gain of that antenna is, but -484 dBm seem
unreasonable....<br>
