Wireless mics typically operate in the (UHF) range, far away from 72 MHz or 216 MHz. So, you might think you don't need to coordinate. This is a dangerous myth.

If printing this as a reference sheet:

Unlike 72 MHz, the 216 MHz band has slightly wider spacing (25 kHz as well, but a different noise floor). If you are using multiple M-216 transmitters in a rack, skip every other channel (e.g., use 0, 2, 4, 6) for the best signal-to-noise ratio. comtek frequency chart
