: [Repeater-Builder] 2x RX's or 2x TX's on one Controller Port
Not so Ron. Give it a try - you might be surprised.
I have been using the 4011 CMOS logic in audio
circuits for 30 years and have not been disapointed in
the audio quality in any of the circuits I have used
them
Very true; I know some who swore off the 4066 as unreliable poorly
performing because of their lack of consideration of the
above. Use it
within its limits it works great.
I have a priority-based receiver selector board that I designed many moons
ago for my inbound link concentrator
outside its rails.

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.

The Linker IIa is a 2 port controller with a seperate control receiver input.
The control receiver input has priority over RX1 and RX2, RX1 has priority
over
RX2.Â
Can it mix RX audio from ports 1 2?

Would quad bilateral switches like a CMOS 4066 better for switching the audio
lines?

Hi All, I am looking for a simple circuit that I could use to connect either
2x RX's or 2x TX's onto 1 port of my controller.Reason, I am dealing with a
split site repeater. So I don't want to waste a port for half a system
I have never measured the distortion, but I do try to
keep the maximum voltage swing down to a tenth of the
supply voltage. The CMOS logic will operate all the
way from 5 to 15 volts or so, and at the higher supply
voltages you can have more audio voltage swing.
I don't notice any distortion by

Well, if you're asking me how I'd do it, see the attached. It's a bit
fancier than Jim's circuit, but it's untested because I determined that the

Hi All,

Reason, I am dealing with a split site repeater. So I don't want to waste a
port for half a system, that I could use for another use.
