Re: [Repeater-Builder] TKR-820 PL Control
Mark (or anyone on the list), is there a Kenwood manual that explains events in the repeater concerned with muting, PL DPL, etc.? I have successfully controled DPL (Tone) on the transmitter to facilitate linking using digital PL so that there's not tone transmitted unless there is a valid received signal. It appears to be pretty clean, but one of the locals that uses Motorola radios says something about the 46 Hz is missingstands to reason since I kill the tone as soon as the COS is dropped. I undestand that during a normal transmitter unkey, there is reverse burst or 46 Hz transmission or something like that to squelch compatible receivers. Sure would like a clear explanation of that. If I knew what I was looking for I might figure out how the signaling unit functions in that respect and come up with a method to make a clean Motorola squelch sequence contolled by COS. Any help would be appreciated. de WD7F John in Tucson - Original Message - From: N9WYS [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Wednesday, October 25, 2006 5:32 PM Subject: RE: [Repeater-Builder] TKR-820 PL Control John, Do you have the manual for this repeater?

Re: [Repeater-Builder] TKR-820 PL Control
Thanks Eric. At least I understand the basics now. John in Tucson - Original Message - From: Eric Lemmon [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Saturday, October 28, 2006 7:52 AM Subject: RE: [Repeater-Builder] TKR-820 PL Control John, Reverse burst is used only in CTCSS, AKA PL tone. When digital subaudible coding (CDCSS, AKA DPL) is used, a 134 Hz analog tone is transmitted at the end of the message to close the squelch. In both CTCSS and CDCSS, the transmitter carrier is held on for 180 milliseconds or so after PTT is released, so that the CTCSS tone can be shifted in phase (reverse burst) or the CDCSS turnoff tone of 134 Hz can be sent. Either scheme will mute the receiver's audio while the carrier is still present, eliminating the annoying squelch crash that would otherwise occur. One possible benefit of using CDCSS on a linked repeater network, where each repeater uses a different digital code, is that the 134 Hz turnoff tone is common to all CDCSS codes, causing every linked repeater to mute at the same time rather than sequentially. The down side, of course, is that relatively few radios made for the Amateur Radio market have either CDCSS with the 134 Hz turnoff tone or CTCSS with reverse burst capability. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of WD7F - John in Tucson Sent: Saturday, October 28, 2006 7:25 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] TKR-820 PL Control Mark (or anyone on the list), is there a Kenwood manual that explains events in the repeater concerned with muting, PL DPL, etc.?

[Repeater-Builder] TKR-820 PL Control
Anyone know offhand if it's possible to control the PL during non-COS transmissions with the TX PLL EN on the TX PLL Unit of the Kenwood TKR-820? Or, does anyone know a tried true method to perform this task? Thanks, John in Tucson Yahoo!
