+ | The line at 100Hz in the tuning window is a tuning aid. This makes it very easy to find the exact frequency. In the spectrum display there is a red line at 100 Hz. You bring the 100 Hz peak to this line and the modem will synchronize immediately. A drift “after” locking is not a problem, it is not necessary to always follow the line. | ||

+ | The received, yellow 100 Hz peak should lie reasonably on the red 100 Hz line. |
