Abstract
A radio transmitter is structured to provide frequency hopping of transmitted leakage signals in addition to RF hopping of the RF output signal. A digital computer controls a digital tuner, a TLO, a FLO, and an IF unit to provide the RF hopping and to provide digital-tuner frequency hopping and IF hopping thereby enabling the frequency hopping of transmitted leakage digital tuner and IF signals.
