[Repeater-Builder] TKR-820 CTCSS/DCS EEPROM
Ok, I'm playing around with my Kenwood TKR-820 a bit. I've found the instructions for HEX editing the channel and ctcss information after reading it from the EEPROM, and they work great. But there's nothing about DCS. I'm wiing to try and decipher how to get the DCS, but I need a look at the information from a chip that contains DCS information. Since I don't have a real programmer I can't change mine and then look at it. So if anyone has a TKR-820 with DCS in it and a EEPROM reader, it would be greatly appreciated if you are wiling to read the chip with PonyProg2000 (http://www.lancos.com/ppwin95.html) and send me a copy. Thanks, Jeff, KB1SPH / WQEX694

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.

My club got a new CAT-400. YEAH!!! So I am reading the manual in preparation to connect to the TKR-820. I find out that the CAT-400 does not encode or decode CTCSS. BOOO!!! Now what to do? I could connect an external encoder/decoder. I really do not want to do that. Who would have thought a controller that complex wouldn't have CTCSS decode/encode!?!?!? Anyway, can the repeaters own decoder be used? When I jump pin 1 to ground does that kill the '820's internal CTCSS (pl) decoder? HELP Tnx es 73 de N5NPO Norm

Re: Re: [Repeater-Builder] TKR 820
Jack, 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. If a pullup 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. 73, ron, n9ee/r From: [EMAIL PROTECTED] Date: 2008/07/04 Fri AM 08:44:51 EDT To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] TKR 820 does anyone have a controller model they can share as I have been working with a nhrc controller and don't seem to be able to get it to key the repeater. also using rus instead of cor, didn't see a cor signal on this repeater ?suggestions welcome...N9exJack In a message dated 7/4/2008 3:52:35 A.M.

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.

[Repeater-Builder] TKR-820 Reciever Issues
This one is for folks that know the Kenwood TKR-820 repeater :-) Or how to modify a VCO frequency range :-) I have a known working on 451.125/456.125 TKR-820 UHF repeater that I'm attempting to move down to 441.350/446.350. I've got the chip reprogrammed and the transmit VCO had no problems retuning to the target frequency (441.350). The receive VCO is another story. The manual says that PLL/VCO lock happens when the voltage from the PLL's integrator is between 4 and 5 volts, with a target of 4.5 volts. After adjusting the VCO's variable capacitor (the only adjustment available), the best I can get is 2.5 volts, and I'm getting a slow sawtooth on the integrator output from the PLL. This is surprising to me since it seems the RX and TX use identical PLL and VCO modules, and the RX VCO only has to tune down to 446.350. 5mhz higher than the TX. In any case.. the 2.5v control voltage is obviously incorrect since I cannot key the repeater with my HT at that adjustment. I have pulled the CTCSS configuration chip as recommended in one set of retuning instructions so I should be able to key the repeater without a PL (the repeater controller will be handling that in any case, so that chip will likely never be reinstalled). Any ideas what I might be doing wrong, or any tricks on how to get everything tuned up ??
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.?

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...

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!

The repeater is currently on 462.155 (+5 Meg, with DPL) and I want to move it to 444.550 (+5 with PL 114.8). The radio does not have a channel change knob or channel display, so I assume it is only a single channel repeater (although it appears the EEPROM doesnt care about that). I have tried to fumble my way through reprogramming this, but when I get to the VERIFY portion, I get a failure message. Its apparent Im not doing something correctly, but Ill be damned if I can figure it out. The reprogramming and retuning is the final issues I need to do before I can put this on the air, so Im getting anxious now that Im close to the end. Thanks so much! Mark N9WYS Yahoo!

[Repeater-Builder] TKR-820 Controller
OK Im still working on this machine, but slowly making progress I remember a previous discussion about how to bring controller functions to the accessory plug, but I cannot seem to locate it. What I want to do is interface an external controller to the repeater. Can anyone point me to the right location, or provide me with the proper document/connection points? Thanks! Mark N9WYS Yahoo!
