I want to hear that sound upon releasing the PTT button.
I apologize if I sound like an idiot I'm new to radio equipment and I'm using this for GMRS.
I hear two completely different things in there. One is MDC1200 and immediately after that sounds like a roger beep / EOT / or courtesy tone either on the transmitting radio or the received radio.
The kenwoods that I am familiar with have a separate courtesy tone that doesn't matter if you're using any signalling or not. You can have it make a beep when a received transmission ends (heard only on your radio) or when you unkey, it makes a beep that goes out over the air.
If you want that data burst sound, you'll need to enable signalling which, if MDC is not available, then FleetSync is similar but not quite as annoying to listen to as it's more brief and not as screechy. There's also fleetsync II which sounds more like MDC1200 but is not compatible with. Not sure if your radio does that or not.
One of the great reasons to use GMRS instead of FRS and use a for-real-radio, is so you're not forced to have a silly roger beep. If you're not using the signalling for any purpose other than to mark the end of a transmission or just to sound cool, that isn't always well received. Then again, this is coming from a guy who set up his radios to practically sing "La Cucaracha" upon key up, so I'm being a tad bit hypocritical.
