Ciao Ken,

many thanks for your reply! Your solution inhibit only the noise for an RTX, not the noise for the RX of a repeater. I find a solution ... see my own mail.

Ciao Thomas

 

The squelch “tail” is usually eliminated by using CTCSS (so called PL) on the transmitted signal and corresponding PL detection on receive.  I am not sure how common that is in EU though …

 

On the repeater you need (usbradio.conf)

 

txtoctype=notone

 

With this, Asterisk stops transmitting the CTCSS tone about 600 milliseconds before dropping the carrier – radios that are using tone squelch will not hear any noise at all when the other station stops transmitting. 

 

Some receivers need > 600 milliseconds for the tone squelch action. It is possible to make this time delay longer, if needed.

Hi,
it's possible to avoid the typical squelch noise after the reception of a valid signal from a repeater RX? Is there a specific setting, if yes in what file?
Many thanks for help!
