There was an ARRL HQ station before W1AW. What was its callsign?

----- W1MK


There's a second callsign for the ARRL lab. What is/was it?

----- W1INF


More trivia: There is an IARU HQ call sign. What is it? While it may
have a certain familiarity about it, especially the suffix, what is the
significance of the prefix?

4U1ITU is the station of the International Amateur Radio Club at ITU
HQ in Geneva ... I've operated the station. The significance of the
prefix is that 4U's are UN callsigns.
