HamName
The owner name of a licensed (ham) node, which firmware builds from two HamParameters fields.
AdminModule::handleSetHamMode() joins the call sign and the optional long_name with SEPARATOR — the form hams already use on the air — so KD2ABC plus Attic Heltec becomes KD2ABC//Attic Heltec, and a ham who supplied no long name is named after the bare call sign. The device only ever reports that composed name back as User.long_name, so editing either half means splitting it again: split and compose are inverses over every name firmware can produce.
