I notice the new EASA licences come with the FRTOL printed on them with no expiry.
The UK will not include this unless you have qualified for the issue of a UK FRTOL. This is still a National licence and has nothing to do with EASA. The FRTOL is issued in compliance with Article 37 of the ITU General Radio Regulations enacted via ANO Article 56(3):
Subject to the exceptions set out in articles 51, 57 and 59 a person must not act as a flight radiotelephony operator, a flight engineer or a flight navigator of an EASA aircraft that is registered in the United Kingdom without holding an appropriate licence granted or rendered valid under this Order.
The CAA may issue a seperate certificate or include the privileges in a pilot's licence. The certificate entered in current licences fails to comply with the requirements of RR Article 37!
FCL 040 states
The exercise of the privileges granted by a licence shall be dependent upon the validity of the ratings contained therein, if applicable, and of the medical certificate.
ANO Art 72 exempts the FRTOL from the requirement to hold a valid medical certificate
Requirement for a medical certificate
72 (1) This article applies to any licence granted under article 64, other than a National Private Pilot's Licence (Aeroplanes) or a Flight Radiotelephony Operator's Licence.
UK licence holders still have a FRTOL if they have RT Privileges and it is valid without a medical certificate.
