APX Admit Tone

[quebecradioguy]

Hi guys, did some research around but havent find an answer...

So here it is. When i talk in Duplex or on a Trunking System, i do have a talk admit tone. now,when im in Simplex i don't have the admit tone, and i can't find it anywhere in the CPS..

Any Help would be appreciated

The talk admit tone means your radio has successfully accessed the trunking system and you can go ahead and talk.

Since simplex doesn't requiring accessing a system, there's no reason for a talk admit tone.

In other words, that setting doesn't exist.

You might consider adding MDC to your simplex channels.

You can alias the MDC ID to an actual alphanumeric ID for each firefighter.

Set the PTT-ID to Leading Edge and enable the Sidetones.

There will be a brief chirp as the MDC ID is sent. This is as close to an admit tone as you're going to get.

My APX6000 does give a single beep every time I transmit on a repeater or simplex freq.

Can you tell me how to do so, or send me a Codeplug so I can compare??

Thanks

If your radio is secure equipped you could enable clear tx tone for your conventional stuff and not have any secure button programmed in or personality set to go secure. While it is just a beep letting you know it's keying up in clear it does say hey your transmitting per say. The pre mdc with short side tone on your conventional would be better I think. It will also help identify anyone sitting on a radio wrong keying up holding the channel and get ahold of them by other means then everyone trying to get on saying check your mics when we know it won't help.

Well, does MDC works with P25 Simplex? I know I can do it with our iTac/iCall Channel which are Conventionnal, but I've never seen the setting for MDC in P25.. and Yes our radios are Basic secure(no AES or stuff like that) just the ADP, which is used for a few Chief band which are encrypted

MDC1200 is an analogue only signalling feature.

Your itac/icall channels are analogue, which is why you can use MDC1200.

but I've never seen the setting for MDC in P25.

You won't. When you transmit P25, whether conventional or trunked, the unique radio ID is embedded with in the data stream. Even if you could send MDC1200 while transmitting digital, it would be redundant.

Use the Transmit Clear Alert tone. It sends a short tone every time you keyup when you are not encrypted.

This is exactly how I did it.
