When I was 15 years old and passed the Novice license (the entry-level license in the US), I was issued WN8ICQ. When I upgraded six months later the callsign automatically was changed to WB8ICQ and I’ve kept it ever since through 7 geographic moves and two more license upgrades.
At first I found it burdensome. I was convinced that I was missing any DX station with marginal copy, as the DX station would conclude “Oh, that guy isn’t calling me, he’s calling CQ! Time to move on…”
More recently I’ve decided that “I CQ” is a distinctive call sign and I am proud to have it.
