Was having a nice chat with Gary, WB0RUR, this morning on 40m PSK-31. His signal was clear, he’s a very experienced operator — yet he was jumping all over the waterfall with every transmission. I couldn’t understand why, but after his signal jumped, stopped, started, moved again, I caught a very brief TX: “QRM … cat

Gary explained:

“Sorry about that … he stepped on the keyboard and stopped my transmission and also bumped the VFO … so I’m probably moving all over frequency.”

QRM would be a great name for a cat.
