Kevin, If you are trying to have 2 repeaters on the same port then simply parrallel the radio I/O. Should be able to directly connect the PTTs and TX audios, but need to isolate the COSs and RX audio with simple resistors. The resistor values will need to be worked with due to not knowing the input/output impedances here.
Of course in this require both repeaters to operate at the same time and what is on one will be on the other. 73, ron, n9ee/r >From: Kevin & Natalia <[EMAIL PROTECTED]> >Date: 2007/11/22 Thu PM 08:12:43 CST >To: [email protected] >Subject: [Repeater-Builder] 2x RX's or 2x TX's on one Controller Port > >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.
