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] RadioShack Recalls Power Supplies Due to Electrocution and Fire Hazards
The primary danger is electrocution, most likely caused by exchanging the neutral and ground leads inside the case. Although the power supply will operate just fine when wired this way, there is the possibility that the unit may be plugged into an improperly-wired receptacle- which happens often when do-it-yourselfers change out a receptacle. If the receptacle ground connection is poor or does not exist, the power supply enclosure can be energized at 120 VAC and pose a severe shock hazard.

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.

OT (sorta)...there is the possibility that the unit may be plugged into an improperly-wired receptacle- which happens often when do-it-yourselfers change out a receptacle. Just a heads-up on the assumption that a professionally wired home is safe. When I bought the house I'm living in now, one of the selling points was that the old knob-and-tube wiring had been replaced with new Romax and a new 125 amp breaker panel (by a professional electrician). All of the outlets were the 3-wire type so I ASS-UMED that all was well and good. The house even passed a buyer's inspection as part of the sale. Well, things were not all as they appeared. After getting smacked a couple of times on the bench, when I knew I shouldn't have, I started looking. Although all of the outlets in the house were the 3-wire type, only the ones in the kitchen (not even the bathroom) had the third wire ground actually connected. All of the others were wired with 2-wire Romax and NO ground. Now, if that isn't a booby trap, I don't know what is. So, unlike me, don't assume anything. Buy a cheap line tester and check every outlet you have in the house. It may save your skin!

My mother-in-law's condo also had a problem. My electrician neighbor came over to do some wiring work and found out that the outside outlets were not connected to the GFI. We figured that the original contractors working the job were tired of resetting the GFI all day due to their faulty tools, so they bypassed the GFI. Then they forgot to rewire it back when they were done. These guys were prime candidates for the Darwin Award. 73, Joe, K1ike Tom wrote: OT (sorta)...there is the possibility that the unit may be plugged into an improperly-wired receptacle- which happens often when do-it-yourselfers change out a receptacle.

Can you imagine this happening in a residential / commercial bathroom where the GFI is compromised? I'd relate that to old sparky in one of the state's pens, (say in Florida) where the lethal death penality still exists. My Dad was an electrician and an electrical inspector for a city in Wisconsin. I still remember to this day when he would be out inspecting jobs, me along with him, and get really MAD when he saw something like you have just described. I'll never forget the day when he called up an electrical contractor and told him if he didn't fix the problem within 24 hours, he would yank his license and refer him to the police department for endangering the public's welfare. He was not a liked inspector, but was trusted within the electrical community. And he slept very well at night.

RE: [Repeater-Builder] RadioShack Recalls Power Supplies Due to Electrocution and Fire Hazards
Don, Your dad is a man I can relate to and admire! I am an ICBO/IAEI Certified Electrical Inspector, although that has nothing whatsoever to do with my employment in the aerospace business. Nevertheless, I see inadequate and sometimes dangerous electrical installations almost on a daily basis My next-door neighbor once called me over to check some wiring he added to his garage for some power tools. He had run some 18/2 SPT, commonly called zip cord, from a light socket above his washing machine over to a receptacle box he added for a drill press. He said that the drill press stalled easily, and he often smelled a burning odor. Duh! Not only was the zip cord extension a violation of several articles of the National Electrical Code, but it was undersized for the load and there was no grounding conductor! He was absolutely clueless about safe and legal electrical wiring. At my urging, he hired a competent electrician to install a new and dedicated branch circuit for his workbench. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Don Kupferschmidt Sent: Friday, July 04, 2008 5:47 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] RadioShack Recalls Power Supplies Due to Electrocution and Fire Hazards Can you imagine this happening in a residential / commercial bathroom where the GFI is compromised?

[Repeater-Builder] Re: RadioShack Recalls Power Supplies Due to Electrocution and Fire Hazards
Nevertheless, I see inadequate and sometimes dangerous electrical installations almost on a daily basis... Another war story that goes with your comment. Shortly after I retired, I took a job with a company that was located in a former International Harvester building doing general maintenance type work. Part of that job included running over the rough concrete floors with a cleaning machine. In one unused part of the building, I saw a length of several fairly heavy wires lying on the floor, near a puddle of water (the roof leaked in that section of the building). I thought I'd just coil them up and hang them on a spike on the wall near where they originated. I picked up the wires and started to coil them up and as I straightened them out I hit the end of the wires and they soundly hit me back with one of the most painful shocks I can recall receiving. It turned out that those lines were part of a 440 volt, three phase line that was never turned off when the equipment was moved out of the area. Once again, I was very lucky in that the only injury was one gigantic scare over what might have happened. Another lesson, never ASS-ume that a line is dead until you confirm it. Had my other hand been grounded, I probably wouldn't be telling this story now.
