...can you post an example of what you have in one of your .mis files? if i see an example i can figure it out...

Apologies...I was reading from the v1.12 Readme, where setting Home Base friction is done in the FMB. In v1.01, you have to do manually.
I'll paste the relevant parts: (New Guinea map, by the way)

Everything there is generated in the FMB, except for the last section, which was added by hand in Windows Notepad. The Readme refers to using the Friction Tool, but it's easy enough to hack with Notepad. It is the X,Y coordinates describing a rectangle, and a friction value to apply to that rectangle. The coordinates are represented as X1 Y1 X2 Y2 Fv, where X1,Y1 is the upper left corner, X2,Y2 is the lower right corner of the rectangle, and Fv is the friction value.

[BornPlace] is your Home Base, 3000 is the default Home Base radius, and the next two values are the X,Y coordinates of the centre point. To keep it simple, I just added and subtracted 3000 from each of those values to get the X1,Y1 X2,Y2 coordinates of my friction rectangle, which is a 6000 x 6000 square centred on the Home Base.

This works in Multiplayer, by creating a dogfight server, but I haven't tried it as a Single Player mission.
