Yes, this is what I used to go by.
QRM used to be always for splatter from another station on adjacent frequency due to too wide bandwidth he is transmitting in, or bad modulation, or some one talking over the station I was listening to.
QRN was always for static or buzzing noise, and I have no clue where it is coming from.
