The Wikidata link is for exact matches otherwise you break the linked data inferences. Moreover, in Wikidata the call sign for radio amateur is a subclass of call sign so this already included. We don't add links for all possible subclasses, that would be superfluous. —M!dgard (talk) 18:17, 28 June 2021 (UTC)

@M!dgard: That's fine. I certainly agree about reserving this property for exact matches. Your point about amateur callsigns already being included as a subclass makes sense. – Minh Nguyễn ^💬 20:23, 29 June 2021 (UTC)
