In one of the schematics under 'prosjects' (15W FM Transmitter to be precice), a BLY88C transistor is listed under parts.. however, this has proven hard to find where i am (norway).. so is there an alternative that would work just as well?
This happens a lot. The best thing to do in such a case is to find the data sheet on the web and look for another transistor that has comparable specs. It might take a while.
