    Fldigi Help File in PDF format.

    Many of you using Fldigi are off-frequency, some by only a few hertz and some up to several hundred hertz, even when your waterfall is showing you are centered on 1,500 Hz. To prevent this, you should calibrated your system.

    Download the help file and go to section 6.4 Digiscope Display - WWV mode on page 260 for instructions on how to calibrate the offset of the sound card oscillator. Once calibrated, you should be correctly centered on frequency.

    Reading this section, it sounds like it could be difficult, but it's really very easy and highly recommended. When we use the TxID and RxID, the frequency and mode can automatically change to the frequency and mode the transmitting station is using. Also, being properly calibrated stops the frequency hopping following each other up or down the waterfall.
