hello wt team, I have a little probleme with my personnal VHF.DTB database under WT4. I have try on WT3 to prepare a IARU VHF contest with this same database and it works good. With WT4, callsigns/locators known with WT3 are not recognized by WT4. At started of WT4 I see the vhf.dtb file it's loaded. Any idea ? 73 cedric F4EGZ
