It is 27mhz.
Here is how KO explained it to me. What KO does, is they make (12) 27mhz channels. The even number KO channels are essentially our normal 1-6 channels in U.S.
FM02 = Channel 1
FM04 = Channel 2
FM06 = Channel 3
...So on, so forth
FM12 = Channel 6
Now the odd numbers KO channels (FM01, FM03 and the one you have FM07) are the "in between" channels.
