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 transverter can be used. This crystal oscillator is frequency stabilized by our 40 °C precision crystal heater QH40A.
A bigger attenuator at the IF input port allows an input power of up to 5 watts. Great large signal performance is achieved by the use of a high-level ring mixer. Self-resettable polyfuses prevent damages of the transverter module, especially if it is used in a portable station. Of course, all the well-tried functions of the old transverter version are kept in the new design!
The small mechanical dimensions of the transverter, which is designed in SMD technology, allow the construction of a small portable station as well as a powerful home station.
