Since June, 13th 2012 the 630m band from 472 to 479 kHz has been released in DL for amateur radio service. Therefore a transverter was developed for this frequency-range. The allowed effective radiation power is 1 Watt.
Please note: with most used antennas you will have to produce at least 1 kW HF, to get 1 Watt radiated !
