... The varactor modulator in the NTX2 introduces some 2 necessary by predistortion of the analogue waveform. Although the modulation bandwidth of the NTX2 extends down does the NRX2 it is not advisable to use data containing a DC component. This is because frequency errors and drifts between the transmitter and receiver occur in normal operation, resulting in DC offset errors on the NRX2’s audio output ...
