and that's not enough!!
consider that now as now for the controller working at the radar position we still read SWR like swissair and CRX like crossair but the new call sign is swiss. Exactly the same of Zurich and Geneva upper sectors , above FL300, since 21 march; so you see a crx label and you say: Swiss2552 contact swiss 124.03" .
Call yourself is faster!!!
