Eric, Thanks for that I will have to check my CPS as we run XTS2500's and on some channels the squelch tail is almost deafening when the repeater drops. I will have to take a look and see what our settings are and get them adjusted.
Thanks for the information and reply.

When checked, the radio is programmed to encode and decode CTCSS reverse burst in the 180-degree format used by Kenwood and many other manufacturers. When unchecked- its default condition- the reverse burst is processed in 120-degree format, which is the Motorola standard. This must be properly programmed for each personality, since it operates on a per-channel basis. I use my HT1250 on a mixture of Motorola and Kenwood repeaters, and it is really nice for it to mute silently- both on my end and the repeater end- on all repeaters. All radios in the system must have reverse burst operative in both encode and decode mode for this feature to work properly. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] <mailto:Repeater-Builder%40yahoogroups.com> [mailto:[email protected] <mailto:Repeater-Builder%40yahoogroups.com> ] On Behalf Of Peter Dakota Summerhawk Sent: Friday, December 11, 2009 9:54 PM To: [email protected] <mailto:Repeater-Builder%40yahoogroups.com> Subject: RE: [Repeater-Builder] RE: 50 Watt Repeater Eric, So what settings should you have for the Motorola radios to avoid the squelch tail in the system?

Kenwood chose to equip their products to process only the 180-degree phase shift reverse-burst squelch tail elimination scheme, while Motorola Professional Series radios can be programmed for either 180-degree or 120-degree phase shift. TIA-603-C, the international standard for land-mobile radio performance, recognizes both reverse schemes as equally viable. Kenwood may recapture some market share, once their radios are equipped to encode and decode reverse burst in either scheme. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> [mailto:[email protected] <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> ] On Behalf Of Paul Dumdie Sent: Friday, December 11, 2009 8:12 PM To: [email protected] <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> Subject: [Repeater-Builder] RE: 50 Watt Repeater I have a TKR-750 repeater and like it. My only issue is that I use Motorola Portables and keep getting a squelch crash. What have you guys setting the setting for the reverse burst at to get rid of the squelch crash? Thanks! Paul R.
