RE: [Repeater-Builder] TKR-820 CTCSS/DCS EEPROM
Jeff, I suspect you may be headed for disappointment. CTCSS (PL) and CDCSS (DPL) are handled differently within the radio. While the former is audio, albeit sub-audible, the latter requires a DC connection to the modulator in order to create the DCS signal at a 134.4 Hz rate. In other words the CTCSS hardware will not work for CDCSS. Perhaps some readers who have TKR-820 stations with CDCSS capability can advise you about the modifications and/or optional modules that are necessary to handle DCS. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of kb1...@wqex694.info Sent: Thursday, July 15, 2010 7:03 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] TKR-820 CTCSS/DCS EEPROM Ok, I'm playing around with my Kenwood TKR-820 a bit.

Re: [Repeater-Builder] TKR-820 CTCSS/DCS EEPROM
Ok, let me make it a little more clear for anybody that might not have understood the first message. (No offense intended Eric) A Kenwood TKR-820 repeater has CTCSS and DCS encoding and decoding built into it with an on-board controller. The configuration is stored in a EEPROM chip, 93C46 (or 93LC46). What I'm trying to do is figure out how to change the configuration without using the expensive Kenwood programmers, unfortunately this one isn't just a simple cable. I have a serial EEPROM reader/writer, so I used instructions found in the repeater-builder archives at http://www.mail-archive.com/repeater-builder@yahoogroups.com/msg63481.html to modify the configuration for the ctcss tones. Unfortunately, the person who wrote that article didn't figure out the DCS configuration. So I'm hoping that someone who has a TKR-820 already configured for DCS has the ability to read the EEPROM chip as well and send me a copy. I hope that clears it up a little more.

Re: [Repeater-Builder] TKR-820 CTCSS/DCS EEPROM
Well I'm not particularly needing any one code at the moment, just trying to figure out how exactly to figure out the hex codes. Thanks for the great tutorial on the rest. It makes it easy to change the config when I want instead of having to call someone with a programmer. Now if I can find a connector that goes into the socket on top of the display board I could just wire up a connection to the ICSP connector on my board and make it easier for the frequencies. This information should be put on the repeater-builder web site if it's not already. I couldn't find it, but maybe I didn't look close enough.

Re: [Repeater-Builder] TKR 820 COR COR logic (and LDG Voter Interface)
Actually, the Kenwood TKR-820 Repeater COR COS logic output changes state with valid activity but the voltage transitions are not standard values you'd expect. Measure the actual voltage change because I've found some of them to be slightly different per actual hardware version of the repeater. I would not blindly connect pull-up or sink resistors/logic to the output connection because the line ties direct back to the uP board section. You don't want to make a mistake and blow out the internal Repeater COR/COS logic by back-feeding the wrong potentials on the lead... The fix is not simple or pretty You can use a simple comparitor circuit to level transition the changing state to a more standard active low/high value as in zero to +13vdc (or +5v) or the converse. Some years back I designed and constructed a small interface board to work with a large number of TKR-720 Repeaters and the LDG Voters... not only do those circuits still function well... the circuit pretty much interfaces (detect) ANY - COS, Squelch, COR or logic state change and outputs a choice of active low/high logic and or a form C type relay connection(s). I use the interface boards for a fairly large number of commercial radio projects. The logic board can be used to detect just about any voltage change in a circuit and I've liberally used them in many other applications. I'm about ready to run off another batch of Any Value Logic Interface Boards so that circuit will be available as a complete product later this month (if the circuit board mfgr finishes on time). I'll also have specific connection information available applied to the Kenwood TKR-820 Repeater circuit. If you need more Kenwood Repeater interface help before the board/circuit is again available to the public, please do feel free to Email me direct (I'm an Authorized Kenwood Service Station) for more help. You don't have to buy anything from me to obtain information and support. cheers, skipp skipp025 at yahoo.com www.radiowrench.com One thing to look at on the TKR820. The COS might require a pullup resistor to make it go high. Often they are open collector that just pull to ground and let float when wanting to go high. The mentioned TKR-720/820 Repeater COS/COR logic ouput is not a standard configuration. If a pull-up is needed probably a 4.7k will do. To check this measure the COS with voltmeter to make sure it is swinging high and low. High would probably be 5 or more volts and low less than 0.5 volts. You will find the COS/COR line to change value from some point about 4 volts to another value depending on any other attached devices and/or parts.

Seller claimed the repeater was removed from operation, and it was labeled 451/456 - so it should be the right one to tune down The 1st 4 bytes are CC 84 3C 83 if you can compare that to the data your programmer would write.. The target frequencies are 441.350 TX and 456.350 RX I've already removed the chip and installed a socket . I'll consider sending the chip if no other viable solution comes up. I don't know what T band is, unless that's the 470-500 version of the repeater. How would I tell ?? I don't see any particular markings on the chassis or boards that would tell me what exactly I have..

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.

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.?

RE: [Repeater-Builder] TKR-820 Timeout Timer Problem - Frustrating!
Byron, It sounds like we have identical repeaters - TKR-820 with CAT-300 controllers... I was pretty certain that I needed to ground Pin 1 before the external controller would work at all, but I'll go back and check that out! If memory serves me, I grounded it to chassis ground in the repeater itself. Does Pin 1 need to be brought into and grounded in the CAT-300 controller? Maybe *that's* where my problem is coming up...

Re: [Repeater-Builder] TKR-820 Timeout Timer Problem - Frustrating!
sounds like you need to try to rewire the whole system, separate the TX and the RX and wire them into the CAT 300 separately. i have never been fond of systems that use an internal controller. i would rather have 2 separate radios, one for TX and one for RX and tie them into the controller. just my 2 cents worth. 73 STEVE - KC8RSR [EMAIL PROTECTED] http://kc8rsr.tripod.com/ AIM / YAHOO = KC8RSR ---Original Message--- From: N9WYS Date: 11/09/05 22:24:11 To: Repeater-Builder@yahoogroups.com; [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: [Repeater-Builder] TKR-820 Timeout Timer Problem - Frustrating! Before you all banish me to the outer reaches of Mongolia - or somewhere else - because of all the questions I keep posing about this machine, please understand that I have tried to research this issue in the technical material I have available to me and I keep coming up empty. This is why I keep prodding. I know there is quite a wealth of knowledge here, so Im trying to tap into some of that knowledge That being said, heres the latest on this frustrating issue. I have a TKR-820 interfaced with a CAT-300 repeater controller. The CAT-300 operates fine, whether the internal controller is turned ON or OFF. The only issue I have is with the internal timeout timer. Previously, the repeater would shut itself down after 2-1/2 minutes when the internal controller circuitry was turned OFF. (REPEAT button OFF) The external controller was set for a much longer time, so I knew it wasnt the CAT-300 causing the problem. I went to the site a few days ago, and adjusted the TOT pot on the internal controller to its maximum (5 min). I then made certain that the external controllers TOT was set shorter (4 min) than the internal one worked just fine. (So I thought ) I departed. Apparently, I departed prematurely. (No jokes here, OK? Hehehehe) Anyway, this evening I heard two stations using the repeater and at 5 minutes the repeater dropped. DAMN!! I went back out to the repeater site to trouble check some more. I found that if I unplug the external controller and have the internal REPEAT function turned ON, the internal controller controls the machine I expected this. (Not what I want!) If I unplug the external controller and have the REPEAT function turned OFF, the repeater does not repeat plug the controller back in, and the repeater works. (This IS what I want!) However, if I dont turn the REPEAT function ON, the repeater times itself out way too soon I presume that this is because of the INTERNAL timeout timer So, how do I totally disable the internal timeout timer? It is becoming more apparent that the timeout timer functions in two ways the first, as a repeater timeout timer (of course); but secondly, as a stuck mic timeout timer when the radio is in base station configuration (simplex operation) This has really frustrated me, and now Im on a quest to figure out just how to shut that damned internal timeout timer off once and for all. Any suggestions?? Can I just unplug the internal controller board altogether? Mark N9WYS YAHOO! GROUPS LINKS Visit your group Repeater-Builder on the web.
