MKU LO 12 PLL
PLL-stabilized Crystal Oscillator
Differenz frequencies (see table)
Now, an external 10 MHz reference frequency can be connected to achieve highest frequency accuracy. This is necessary for EME, WSJT and Tropo DX. The frequency of 10 MHz can be supplied by a highly stable OCXO, a reference oscillator of a frequency counter, a rubidium frequency standard or a GPS controlled frequency source.
If a 10 MHz reference frequency is not available, the internal crystal oscillator of the unit can be used. This crystal oscillator is frequency stabilized by our 40 °C precision crystal heater QH40A.
