CW Pitch: If the receiver is tuned to an exact "zero
beat" on an incoming CW signal, you could not copy
it ("Zero beat" implies a 0 Hz tone). Therefore, the re-
ceiver is offset several hundreds of Hz (typically), to
produce a beat tone that can be heard. The BFO offset
associated with this tuning (that produces the comfort-
able audio tone) is called the CW Pitch.
