[Repeater-Builder] CSM1000/R2590 wanted
I would be interested in a CSM1000 (Link-Comm) or R2590 (Motorola/General Dynamics) service monitor (basically the same) if available for a reasonable price. These were budget service monitors afaik but small and portable compared to the HP E8285 I'm currently using for bench work and which is just too bulky and heavy for hauling to the repeater site... As a repeater builder I'd be interested in the tracking option. In case somebody has a spare one or knows somebody who has please make me an offer (I don't know exactly what these are traded for) or get me connected. Regards Martin

[Repeater-Builder] Re: Micor PL encoder modification (TLN5731A)
Hi Paul, I modified a non-unified chassis 5 years or so ago. I wanted to disable the tone during cw id, so I used a small reed relay and broke the pl audio right at the input on the exciter board. I believe all I did was to put one end of the relay to 12 volts and the other end to a diode or gate. I don't quite remember how it went all together. I'll see if I can find the documentation and let you know. HTH Sean ve3hxp --- In Repeater-Builder@yahoogroups.com, N1BUG p...@... wrote: I'm guessing I am not the first to want to do this...

[Repeater-Builder] Programming Kenwood TKR-820 without KPT-50
I'm looking for information on how to program and edit binary files for the 2 EEPROMS in the Kenwood TKR-820 UHF repeater without using the KPT-50. I have IC programmers available through work. Thanks, Steve AB5ID
Re: [Repeater-Builder] Programming Kenwood TKR-820 without KPT-50
Brute Force Hacking the TKR-820 / 720 Series Hey, these make great little repeaters. They also are becoming fairly common on the surplus market as companies are caving into the idea that digital cellular is a better alternative to NBFM. Well anyway I am sure you bought one for cheap or acquired one by some other means with the thoughts that you could drag it into the ham band. So lets begin. First lets make sure the repeater works. Start by connecting a watt meter with dummy load to the TX port (Or the antenna port on models with the built in duplexer). Use the 25W 200-500 or 400-1000 slug are the closest thing you have. Loosen the squelch until the repeater goes into transmit mode, remember to press the repeat button on the front panel. Won’t do it? Turn the unit off pull the covers and remove the 93C46 EEPROM from the controller board (This is the little board that is about 3X5 and sits above the radio chassis’). This sets the DPL/PL combination and without it the repeater will activate on COS. Turn it back on and it should repeat. Got RF power? Good. Set this little bastard aside as we will deal with him later. Next step is to take write down the voltage on the from the test points besides the VCOs. The VCOs are located under the metal tray that the controller sits on. This should be some where around 4 volts DC. Now we have to come up with a way to change the data that sets the frequency of the repeater. For some reason the chip that does this is on the circuit board on the front panel of the repeater. I was originally told that “Either a KPT-20 or KPT-50 is need to program those. No way around it.” That sounds like a wager to me. Sure if you have a Kenwood dealer around that you can borrow one from or willing to spend more than you bought the repeater for this is a sure fire method. Oh, you will also need the KPG-21D software, but it will not allow operation into the ham bands and has some serious compatibility issues running on modern hardware. Unsolder the 93C46 EEPROM from the front panel board. Use what ever method you like, I prefer my trusty static free Soldapult. Be careful not to rip and leads off the package when removing it. Place an 8 pin DIP socket in the hole that you got the EEPROM out of and solder it down. Now we get the data out of the chip. I built a serial port to EEPROM interface found here: http://www.lancos.com/e2p/siprog_base.png and http://www.lancos.com/e2p/si-prog-v2_2.pdf in order to be used with the device programming software “Pony Prog” http://www.lancos.com/prog.html. You have to build the base board and then the socket for the device you wish to program. I replaced the LM2936Z-5 in the schematics with a 5.1 V Zener diode fed with a 330 ohm resistor to generate the +5 needed, and BC547 is the European equivalent of a 2N3904. This way all parts can be obtained from your local Radio Shack, or your parts box depending on how much home brew you do so well. So once you have the interface built and running you can read the EEPROM contents. The settings take a little while to get used to. All you want it to output to is a raw binary dump with no header information saved. Open the dump with a hex editor. I like XVI32, http://www.chmaas.handshake.de/delphi/freeware/xvi32/xvi32.htm . Pretty hard to beat free. Now for some reason the Pony Prog spit out information that is interleaved. This is evident by the way the data is arranged at H7A, Which on my dumps is 8R021N. On a Kenwood KPG-21D generated image this should say R820N. Anyway, it makes the hex coding easier to understand when doing the channels. If you are using a different chip program that did it right you will have to swap the bytes around, i.e C884 to 84C8. It should be obvious when you do the calculations and your frequency is in the 650MHz region. Receiver frequency data starts at H00 and it 2 bytes long. In my binary image I have H8338. Open up the windows calculator and place it in scientific mode (Or you can use a decent calculator that will convert Hex to decimal such as the TI-36X.). Press the “Hex” button and enter in the data that you have. Then press “Dec”. H8338 = 33592. Now we multiply this by the channel stepping. 12.5 for the TKR-820 and 5 for the VHF 720. 33592 * 12.5 = 419900. Now we add the IF frequency 419900 + 21400 = 441300 441.300MHz. You still with me? Good. The transmit side is the exact same thing, but starts at H02. I find this odd that both the transmit side and the receive side use IF frequencies on the synthesizers, but what ever. Now that you have reverse engineered what channels the repeater is on, Stick that chip back in there. You get to do…. More testing. If you have the internal duplexer now would be a good time to bypass it and go straight into a watt meter and dummy load. If you are satisfied with the repeaters performance you may continue to changing the frequency. Figure out the target frequency you want and we will go from there. 443.400MHz RX 443400 –

RE: [Repeater-Builder] Re: LDF1-50 with PL259 UG-176 ?
Depending on the PL-259 in question (i.e. who manufacturered it), sometimes you can get them onto FSJ2 without any problem, other times you need to take a bit off the threads to get it to thread onto the shield. But to complicate matters, some PL-259's are manufacturered such that the ID in the area where the solder holes are located is too small for FSJ2, in which case, you can't use those, unless you just thread them on up to where the ID tapers down, and then sweat-solder the shield to the PL-259 from the rear (i.e. you won't be able to solder through the solder holes). The center conductor fits into the PL-259 pin no problem regardless of manufacturer. Bottom line - try a few PL-259's and stick to manufacturer that works. If I could remember which ones do or don't fit I would tell you, but to be honest, I don't use PL-259's very often, so when I do need to put one on FSJ2, I usually just try a few until I find one that fits... --- Jeff WN3A -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Howard Z Sent: Tuesday, May 04, 2010 10:18 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: LDF1-50 with PL259 UG-176 ?

[Repeater-Builder] FS: UHF Vertex VXR-5000 w/ RI-210 Controller
I have available a VXR-5000 repeater, production code 45H259J. This translates to 450 - 470 MHz, 25 kHz, 25 watts continuous duty, internal AC supply with 12 volt backup option. The repeater has the internal Pacific Research RI-210 controller, which is hard to find these days. Full manuals on both the repeater and controller are included, but no duplexer. Repeater and controller are in great working order. Although this is wideband, Vertex made this unit in a narrow band version. The documentation has all the parts values needed to change the channel spacing --basically, a few chip resistors and capacitors need to be changed and the IF filter replaced. I am not representing that these changes would make it legal under the new narrow band rules for part 90 but it can easily be done. Please contact me off-list if interested. fwb...@mminternet.com
