This is really opinion based though. Like I personally think it's dumb to make your call sign something like "PWND" or spelling out other words using 4 letters. I think of actual military call signs being a name/letter and numbers. Like Tango 6(T6 maybe), or Kilo 147(K147). Those make more sense to me. Maybe I'm just reading too far into it lol.
