What? It would seem to me that your repeat audio is not going through the controller, or maybe not all of it is. I have seen instances where the _original_ audio path in a repeater hadn't been removed when a controller was installed, and the situation you are describing happened. The NHRC-4 controller is designed to mute the audio any time the COS light is out. It handles audio muting and keying with and squelch logic, so unless something is wrong with the controller, the audio should mute when the PL is removed (minus a short response time). Could it be possible that you have two audio paths? Doing some simple tests will reveal it. Push a few touchtones and see if you hear them come through the repeater transmitter (assuming you have DTMF muting enabled). Turn the RX audio pot all the way down and see if there is still audio passing through the repeater. Scoping the audio path will also help you determine were the audio path is going astray. Kevin *
Re: [Repeater-Builder] NHRC-4 CONTROLLER AND TS-32 TONE BOARD
Looks like you aren't decoding and processing CTCSS and COR like I am. However, I don't have a NHRC controller, so I won't be much help with that. Anyway, my controller provides a logic output that I use to gate the encoder. That way both CTCSS decode and COR are involved. If your controller won't do that, then you'll need to design some logic that takes both CTCSS decode and COR into account. Contact NHRC for some suggestions.

I have a similar design I think where I use the COS to turn on a transistor that operates a relay that the encoder goes through. My problem is that after a CTCSS Signal activates the NHRC-4, any interference or signals on the frequency can come thru the tail. Now those signals are not transmitting CTCSS but the repeater is repeating them with carrier squelch as long as the tail is up. Once the tail drops, it stops until a CTCSS Signal opens the controller and again the tail will transmit the signal. Have you experienced this? It appears that I need to take the COS signal from the DECODER so when the DECODER drops, the controller will MUTE the tail. Possibly I have problem with the controller not muting. Any ideas? Here is an example: I put the service monitor on the MASTR II and transmit a carrier without CTCSS. Nothing happens. I apply the 107.2 tone and the controller comes active and re-transmits the signal OK. I stop the CTCSS tone from the generator and let the carrier transmit and the repeater tail will transmit the noise from the generator for the duration of the tail.

If you are going to use a relay, simply use a set of the relay contacts to break the encode output line.
