Each + audio and DC power lead should be bypassed with a .001 uF capacitor, one side of the capacitor to the lead and the other to the metal case. The ground lead of the audio and DC power lead should be directly mounted to the metal box or rf bypassed to ground with a .01 uF capacitor, one side of the capacitor goes to the metal case and the other to the ground lead. At a minimum, there should be an RF low-pass filter on the last RF amplifier stage before the coax feeding the antenna. A deviation limiter should also be employed. PLL should be used to stay on frequency. How to eliminate RF feedback problems. This is heard as hum and buzzing in the audio equipment such as a cd player and microphone. The audio and power leads leading in and out of such equipment must be RF bypassed! The audio is done in the same manner as the audio leads that pass through the metal box in any of the FM or AM transmittter components. For ac power leads make sure that the voltage rating of the capacitor is much greater than 120volts or 240volts. Both of these ac power lines(hot ...
