Apparently, it's illegal if the intention is to
obtain information, or to
disclose the content...
My guess is that general interest, as in SWL, isn't intention to obtain information. But I'm not a lawyerÂ
Unauthorised receptionThere are two criminal offences relating to unauthorised reception: interception and disclosure. See section 48 of the Wireless Telegraphy Act 2006.
InterceptionIt is an offence for an unauthorised person to use wireless telegraphy apparatus with intent to obtain information as to the contents, sender or addressee of any message whether sent by means of wireless telegraphy or not, of which neither the person using the apparatus nor a person on whose behalf he is acting is an intended recipient.
The Investigatory Powers Act 2016 allows for a number of different organisations to carry out interception of communications and other forms of monitoring.
DisclosureIt is an offence for someone, otherwise than under the authority of a designated person, to disclose any information as to the contents, sender or addressee of any message referred to above. However, this does not apply where the disclosure is in the course of legal proceedings or for the purpose of any report of those proceedings. Furthermore, it does not apply where the information would have come to the person’s knowledge without the use of wireless telegraphy apparatus by the person or by anyone else.
This means that it is illegal to disclose to a third party anything heard in a transmission that a person has listened to without authorisation.
The maximum penalty is up to two years’ imprisonment and/or an unlimited fine.
