Modulation In The 200 Megacycle Band

[PanJurekMrJerry]

Is there any specific modulation ( Analog, P-25, Wide F.M., Narrow F.M., Etc. ) used in the 200 - 225 range?

Any standards adapted for this band?

220-225 is actually two bands. There's a land mobile band at 220-222, and an amateur band from 222-225.

The land mobile band primarily uses ACSSB, the amateur band is mostly FM, although you'll find a very small amount of cw and ssb there.

"Standards"? What sort of standards?

It stopped being called "megacycles" sometime back in the dark ages. It's "Megahertz" now.

It would mostly if not ALL FM Mode

Actually the OP asked about "used in the 200 - 225 range?" and there is also activity in the 216-220 range which I beleive is mostly FM and I know that the amatuer operators have also been allocated secondary status in the 219-220 range for point to point links to replace what they lost between 220-222.
