125 kHz. It has eight possible tuning steps numbered 0 - 7. When you look at the “TEST FREQUENCY” screen you
see something like (124.7 KHZ .5) The 124.7 is the frequency, and the 5 is the tuning step. The decimal point next to
the 5 indicates the funnel is being detected; if the funnel is removed the decimal point should turn off.
