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. 73 Ken From: app_rpt-users-bounces at ohnosec.org [mailto:app_rpt-users-bounces at ohnosec.org] On Behalf Of Thomas Delmonego

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!
