Before we embrace CDCSS as a cure-all, let us not forget that ALL standard CDCSS codes use the same 134.4 Hz turn-off tone for muting. That means that a mobile user keying distant repeater on the same frequency as yours, even if using a different CDCSS code, will mute your repeater at the same time. This is one of the "nasty little secrets" about CDCSS.
Although few Amateur-grade portable and mobile radios provide reverse-burst squelch tail elimination at this time, it will probably become a standard feature before long. There is already a large number of Hams who use high-tier Motorola and Kenwood radios not only for the quality and durability, but also for the silent muting that results from reverse burst. The freedom from annoying squelch crashes is reason enough to use either CTCSS or CDCSS, in my opinion. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of MCH Sent: Tuesday, August 28, 2007 2:17 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: subaudibe tones..
