FrSKY is shipping transmitters to Europe with EU-LBT communication protocol and originally installed EU interface is offering choice between D16 or L12R only, not D8.
As far as I know, D8 protocole has not been modified for
ETSI EN 300 328 V1.8.1
Unless FrSKY produces a new D8 protocole, complying with these rules, D receivers may only be used with transmitters (or XJT, DJT modules) imported in Europe before 01-01-2015.
These D receivers should not be imported in Europe since 01-01-2015.
No problem to publish this answer.
