Re: [Repeater-Builder] Too stupid to run Google??
A method of taking the COR I have used on a radio that I did not have the internal schematic is to locate the wires going to the "BUSY" LED on the front panel and insert the diode of an Opto Isolator in series with the busy LED and take the COR from the transistor of the Opto Isolator. You can get either a positive going COR by connecting the collector to a positive supply and taking the signal from the emitter, or a negative going COR by connecting the emitter to ground and putting a pull up resistor to the collector with the signal taken from the collector. 73 - Jim W5ZIT --- On Tue, 7/28/09, Scott Zimmerman wrote: From: Scott Zimmerman Subject: [Repeater-Builder] Too stupid to run Google??

I have a TM-331 I am making in to a single frequency remote base. Where can I find a COR in this radio? I see TONS of references to using an RBI-1, but I am only using ONE channel.

Where >can I find a COR in this radio? Buried deep inside. The RBI-1 gets COS status info from the serial data stream coming from the TM-331. If you want COS without the RBI-1 you'll need to bring it out. I once found the internal COS logic line in the schematic but didn't bother documenting because I decided to go the RBI-1 route instead. If you need help finding it I can probably dig up the schematics & try to find it again. > I see TONS of references to using an >RBI-1, but I am only using ONE channel. > >Apparently I have been out in the sun too long or something. Maybe >Google is having trouble reading my mind... Yea, That's it!! I wouldn't be surprised if it's not "googleable" since few apparently go the direct COS route with this radio. Bob NO6B

Scott, You can probably find the answer in the Kenwood service manual B51-3826-00. It's available from www.wirelessrepairsandbatteries.com for about $17. I hope you recover soon... 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Scott Zimmerman Sent: Tuesday, July 28, 2009 1:39 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Too stupid to run Google??

RE: [Repeater-Builder] Too stupid to run Google??
You may not be seeing the answer you want to see. Pulling from old memory cells, I think the RBI-1 pulls the COR from a serial data stream connected through the Microphone Jack. I don't believe there is a "graceful" way of pulling the data off a pin somewhere. You may have to do surgery on the guts of the radio to pull out a hi/lo indication like you want. Bummer huh!
