Any suggestions on a good timer / sign off device for an AM daytime station? Something that would fade out of the automation at a precise time, play the station sign off audio and turn off the transmitter.

Looking for professional AM sign off device

Can you program a fade in your automation that plays the scheduled hard timed sign off... then have the automation system output a GPIO closure to interface with the remote control.
Without more information, it's hard to give you better advice.
- Is the transmitter co-located with the studio or somewhere else?
- What kind of remote control is attached to the transmitter?
- What automation system are you using?
- What switcher are you using, if any, with said automation system?
We like to help, but to all that ask questions, PLEASE be specific!!! It helps us as much as it helps you.

My stations use a sine RFC to alter day and night power. Think channel 70 and 71 need to be programmed with date and time.
I think it would be easy to coordinate fade out by automation, sign off, and a minute or so later have remote dump transmitter was my only thought. i assumed, perhaps incorrectly, that most remotes could dump transmitter based on time, or failing a time setting, a closure from a silence sensor, or a dtmf tone perhaps? just trying to share a thought process.
The Sine does have an internal clock and can be programmed to execute a command based on time. Programming is kind of complicated, and it is absolutely essential that a reliable battery backup be used.
The automation system should be capable of fading down a song and stopping at a given time.

I don't think such a product is made as a stand-alone box. Certainly the individual parts have been used in sections of other products. Is there a demand for such a device?
I'm thinking that most stations program their automation to play the signoff and then stop at the required time. Most automation can also close a relay, so if the transmitter's co-located, the automation can turn off the transmitter, too. For remote transmitters, most remote controls have schedulers for turning them off.
If there was demand for a stand-alone solution, we could easily make it, but I've never gotten such a request before. I'd certainly want to know that there would be buyers before creating the product.

Try Broadcast Tools they have stuff just for this here a link to one. Used a ps-99, however that have been discontined, may want to use the schedule Sentinel

A simple scheduler won't work by itself. In addition to relay outputs, to do the job in one box would require onboard audio storage for the message and the normal audio would have to pass through it so that it could fade out of the program audio to insert the sign off message. Fade in/out also requires a VCA or digital pots. It's not as simple as it might seem at first.
All automation systems can take a GPIO input that is mapped to a "fade" macro. All can do hard timed events. Why re-invent the wheel here? Most can output GPIO as well.
Program in a hard fade at whatever time that month you go off. Fade fires off hard timed sign off. When the hard timed sign off is done, a contact closure is output from the automation system to the remote control and/or transmitter relay panel.

Are you sending a single, simulcast feed to a transmitter site, and then wanting to do the sign-off as a split from the FM feed?
