The 70TX-E2 is a professional 500mW narrow band FM radio transmitter according to EN 300113 and has been improved in many respects compared to its predecessor 70TX-E. The innovative concept combines the advantages of the DDS with those of the synthesizer in a unique way. The signal digitization offers a resolution of 12 bit. Further signal processing is completely digital. The result is an almost perfect RF signal with excellent transmission characteristics for both analog and digital signals.
