I cant call ATC on any Airport in FS2002. Did I miss a switch (radio is on).

It works. Make sure you have updated version of the L-39.

Whats the meaning of "brake out over" on the right announciator panel?

It works with BRAKE OUT mode of the ISKRA nav system (it's not modeled in the TLK-39).

At low level I cruise at 90 percent power not faster than 300 kmh. Is that correct?

Just rechecked, n90% H=500m V=340km/h. Anyway, 310-340km/h at 90% that's ok for the L-39ZA. L-39C will go faster.
