Well I can only say that my recent Mk2 PV router (English version) kit came with an RFM69CW …
What I meant in the table was that the Mk2 PV router kit needed to include the RF hardware option and that the appropriate firmware was used.
I don’t know if or when Robin changed from supplying the RFM12B to the RFM69CW. His parts list includes both the RFM12B and the RFM69CW.
I believe there are some discussions at The emonPiCM - #42 by alandpearson on RFM12B vs RFM69CW. I don’t know if this helps.
