I have been searching for scanning regulations in Portugal and have become confused.
Hi
I am from Austria who is in Europe. So the European Law are in the the most country very similar.
(Ok UK is different in many ways...)
Scanning is in the most Country total illegal! Listen to anything else than PMR446, Amateur Radio and CB could be a very hight fine and your Hardware get confiscated.
When you Tune into Gov Channels like Police it could end with an extreme hight fine and as an non European you can spend a long time in a remand prison before you see the judge.
If you have any Mil Freq in your System you could get charged for Spying.
Even talking about scanning arround isnt a good idea. Thats why I am here talk about that an not in an German speaking Forum.
I can bring for air monitoring
You can if you have no Airband Voice Certificate (or how does it called in English) your Hardware can be confiscated to.
So away from the legal stuff. When I travell around in Europe I carry my SDR Stuff like Dongle, Antenna,.. in my Luggage. NOBODY care about! Even for any Radio I use.
If you are not a Radio Amateur with a licence make sure you use Radios who look like PMR446.
What important is:
0,5W....
non removable Antenna (!)
In some country the Analog goes up to the digital channel (446.100 - .200).
