Sicral 1A en 1B are Italian Milsat satellites where you can hear the Italian Navy, telephone, Data and other things.
You can receive them with a good discone antenna or something.
For other Sicral or Milsat frequencies and info, take a look at the Milsat site of Peter de Deugd http://home.wanadoo.nl/psdedeugd/" onclick="window.open(this.href);return false;
A very nice part of the hobby.
