Kerchunk — What It Means in Ham Radio

Kerchunk — Keying up a repeater without saying anything.

Considered rude, and it can put you on the wrong side of the rules. The FCC asks you to identify at the end of each communication and at least every ten minutes during one — a kerchunk with no callsign leaves an unidentified transmission on the air. Saying your callsign takes a second and settles it.
