My understanding is that this a feature that you are able to teleport with full kit to the radio every 10 mins with zero supply cost and only when you respawn to it then it will consume supplies. But who knows how BI has imagined how this should work because this teleport/fast travel thing is not documented anywhere and it seems that most of the players don't even know about this feature.

But I'd say that keep it as it is. This works great as it is. At least for now.
