If the Motorola radios are Professional Series (HT1250, CDM1550, etc.) you can go into CPS and select "Non Standard Reverse Burst" on the Advanced tab. This will program the radio to encode and decode in the 180 degree format, on a channel-by-channel basis. Kenwood will provide a firmware upgrade to accomplish the same thing- but for a fee, of course, and you must send the radio back to the depot to have this done.
I use my personal Motorola HT1250 radio when working with my local police department, which has a Kenwood TKR-840 repeater, and I can also communicate with the County Sheriff Office, which has a Motorola Quantar repeater. Because of the unique capability to select the reverse burst phasing, my radio mutes silently on either radio channel. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Yahoo Sent: Tuesday, January 27, 2009 7:28 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Kenwood TKR-850 question The problem is reverse phasing 120 degrees (Motorola) vs. 180 degrees (mostly everyone else).

Something to do with the reverse burst timing or something. We sold three new '850's to a customer and suddenly all the motorola portables started having a squelch tail at the end of their transmits. ----- Original Message ----- From: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> > To: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> > Sent: Wed Jan 28 19:55:02 2009 Subject: RE: [Repeater-Builder] Kenwood TKR-850 question What did they fix?
