It does, in fact, have an AM broadcast as well as an FM broadcast filter. Depending on your software however, it may be called a "notch filter", not to be confused with an actual carrier notch filter.

I also use MultiPSK for data decoding from my SDR, along with virtual audio cable. ERT does not seem to be supported, however, at least in the free version. The focus seems to be more on the more common Amateur and professional digital modes.
