Hi Kevin, As always thanks for your help. Can I tell you what I am doing and what is happening so you can yell me why?
First the only problem I am having is after the CTCSS becomes active then drops, the tail of the NHRC will broadcast NON PL signals or interference for the duration of the tail. I need to mute the non PL audio coming into the controller after the CTCSS DECODE STOPS. I am using the Repeater Builder Circuit you suggested and the CTCSS Decode goes thru the transistor/relay switch hooked to the receiver COS. Now if there is noise on the RX the switch stays active as it is responding to CAS not tone. I would like to have a way for the switch to respond to tone, rather than CAS. Because I don't always describe things, let me give you an example: I put the service monitor on the repeater and generate a noisy CSQ signal. The receiver responds, but the controller waits for PL. Then I turn on the PL and the NHRC-4 repeats and I hear the noise from the generator coming through the HT set for tone squelch. Now I shut off the tone on the generator and the HT goes quiet. If you listen to the output of the repeater using carrier squelch you can hear the noise from the service monitor for the duration of the tail. The tail closes, the controller stops and all is quiet until another PL brings up the controller. I need to mute the controller without affecting the RX audio or the output that sends the Tones and CW ID.
