It can be in the form of spurious signals If the amplitude of these spurious signals is outside agency-reference-recommendation value, they could cause undue disturbances to other users by entering the receiver systems of other RF bands The generation of spurious signals from a transmitter could be the result of imposed varying antenna loads, noisy voltage-supply lines to the stages of the transmitter, or noncontinuous battery-voltage supply to RF energy from the host.

传输器的不稳定是指传输器产生的伪真信号，这种不稳定性的伪真信号的形成出现，如果它们的振幅超过代理服务器允许值就会进入其它波段的接收系统，干扰使用者，强制性的天线改装，伴有嗓音的电压，断续的供电都会产生为伪真信号，有些电池装配线可接收并解调这种能量，并生成嗓音，然后由经供电线路进入主传输器。
