Re: TKR820 (tkr-720) COR Logic (pin13) information wanted. Wow, this post has some history... y yo necesito mas practicar en espanol Que Lastima! Read on. The Kenwood TKR-720 and TKR-820 repeaters have a cor output logic line with non-standard voltage values. The cor changes dc level with cos however, the dc values are not standard in the form of active high being some voltage and active low going to dc ground (or the converse). I designed and build a simple dc level detector circuit I now use for all my repeater cor/cos and squelch detection circuits. I've got the design down to one very fast adjustment and it otherwise doesn't care what the input voltage values are or where they transition to output a standard form-C type relay or simple FET/bipolar transistor output. It's a viable enough design that I'm having a fair number of pc-boards made to be offered cheap to anyone who might want one in kit or pre-built form.

Re: [Repeater-Builder] Re: TKR820 (tkr-720) COR Logic (pin13) information wanted.
Skipp and others The problem he is facing is really quite simple. According to the service manual for the TKR-820, the so-called "CO" output on the 15 pin Molex style Accessory connector provides an open collector output LOW when carrier is active UNLESS the repeater is programmed for tone decode in which case the CO output is "tone squelch" based (I'm not sure if that means decode only output or it is AND's with COR). In any case, that's what the service manual says. I spent a bit of time on the phone with Kenwood tech support about this the other day and they seemed somewhat "stumped" that it worked this way. He sent me a couple excerpts from the service manual, including this one (which may be the most important piece of info from them so far - this is from Service Bulletin T-89-88-LM) I've posted it on our website (with Kenwood's permission). This may be what Frank is looking for. http://www.arcomcontrollers.com/rc210/t-89-88.pdf Hope this helps Ken At 09:07 AM 5/1/2008, skipp025 wrote: Re: TKR820 (tkr-720) COR Logic (pin13) information wanted.

Now connector for TKR 720/820 repeat control board plug WAS RE: [Repeater-Builder] Re: TKR820
I would like to thank everyone who has contributed to the TKR-820 issues! The 820 seems to be one repeater that there isnt a lot of publicized info free for the asking, we all had to dig real hard, but thanks again to all who answered the bell! Just for the record my serial # is 6035008 which leads me to believe that I have the mod already build in to my 820 and need to do nothing to the board as far as jumpers are concerned.
