Assuming you are using CTCSS, you probably have the DSP squelch set too loose and you are hearing the operation of the CTCSS decoder - which is relatively slow. You need to use "radio tune rxsquelch" with no signal on the machine to set it. For example:

radio tune rxsquelch

Current Signal Strength is 666 Current Squelch setting is 780 You should set the squelch so that it is at least 100 points higher than the background noise level. You set it by typing a number after the command. For example

radio tune rxsquelch 770

Changed Squelch setting to 770 GL Ken From: app_rpt-users-bounces@ohnosec.org [mailto:app_rpt-users-bounces@ohnosec.org] On Behalf Of Joey Smith Sent: Sunday, April 17, 2011 3:33 PM To: app_rpt-users@ohnosec.org Subject: [App_rpt-users] adjusting squelch tail time ?? If possible, Is there a way one can adjust the squelch tail time? (The time from when a person unkeys the mic to the courtesy tone). I got the hang time adjusted where I want it but having trouble getting the squelch tail time down. Thanks
