Although many logic, including NAND gates, operate in linear mode, but not for audio. They simply switch from/to logic 0 or 1.
The 4066 is an analog switch and works very well. One must bias its inputs somewhere in the middle of the power supply voltage so any audio signal will not work outside its rails. 73, ron, n9ee/r >From: [EMAIL PROTECTED] >Date: 2007/11/23 Fri AM 10:35:18 CST >To: [email protected] >Subject: Re: [Repeater-Builder] 2x RX's or 2x TX's on one Controller Port > >At 11/23/2007 03:12, you wrote: > >>Kevin, here is a circuit that I have used several >>times to combine a control receiver with the main >>receiver in a repeater controller.
