The Bitx uses a Double Balanced Modulator (DBM). ?If it's truly balanced it doesn't generate a carrier, just the two sidebands. If it didn't, it's unlikely the crystal filter could remove the carrier. ?The carrier is close to either side band and it's as strong a signal or stronger than the sideband.?

By moving the signal up or down the spectrum by changing the signal frequency. We can theoretically pass the carrier and a small portion of both sidebands by selecting the proper frequency on the dial
