[QUOTE="Mitchell Fosgate III, post: 8894678, member: 691623"] [JUSTIFY]You're using a microphone to talk to your clients or persons on the other side. The microphone goes through the same radio OP AMP and frequencies as that of the radio. Only difference is that the microphone when turned on switches to use one AM or FM frequency. When that happens it draws excess amounts of current or volts to send the signal across via a phone line. AM or FM frequency. This excess volts blocks off the AM or FM station and uses one station from the radio to signal to the other guy on the other side. This excess volts into the radio then causes the other guy to hear an loud echo. The radio is still on, just that the microphone takes over the circuit and uses the OP AMP instead to relay the message. The phone conversation. The microphone and radio uses two different levels of ampere rating. Microphone on a higher voltage reading. This would be one cause of the echo. How to solve? Basically cannot. The volts are needed to transmit the message across and the radio also to transmit with the acquired voltage. So to solve it, place the microphone on another hotline. Voltage line different from that of the radio. Another receiver. That would do it.[/JUSTIFY] [/QUOTE]
