Kenwood TK-940 - Beeping after someone transmits on frequency

[QHaba]

So, I have a Kenwood TK-940 programmed to FCC ID 189, which is my local school bus company. I listen all day and certain times there's a beeping after someone transmits on the radio. It seems to me like a QT/DQT issue, but I'm not sure how to find what QT/DQT they are using.. Can anyone help me find a solution to this?

Thanks

QT and DQT are subaudible, so you wouldn't hear them.

Are you sure it's not an end of message Push To Talk ID, like FleetSync, MDC1200, etc?
or,
Is it only from the dispatcher?

Well, I'm not sure, I used to ride those buses before the virus hit and I never heard the beeping.. It's like Morse code. They don't use fleetsync, they are on a repeater, could it be feedback from a repeater?

It may be Morse code from the repeater. The repeater should ID itself every 30 minutes. Usually the ID is sent without QT or DQT, so if you set that up on your RX side, you shouldn't hear it. If you are running carrier squelch, you will.

How can I set it up and turn off carrier squelch? I use DOSBox to program it.

You just need to change the TX QT or DQT from CSQ to whatever QT or DQT the repeater puts out.
