hi guys what dose this mean in satellite settings should it be on or off 22k tone

A modern "Universal" LNB requires a 22 kHz signal at 0.5v p-p to switch its Local Oscillator to 10.6 GHz ("high band"). Otherwise it uses its 9.75 GHz oscillator.

Something I just read?
22KHz switch is used to switch between two devices. All Free To Air satellite receivers have 22KHz switch capabilities. By sending a 22KHz tone to the switch, the receiver controls the ports. It can be used as a simple A/B switch to switch between two different satellite LNBFs or two different DiSEqC switches. By turning the 22KHz option on & off, or to "0" & "22K" on your receiver, the receiver will automatically switch between the two ports allowing reliable operation that sometimes fails when using a 2X1 DiSEqC switch.
