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: [email protected] >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. >Central Daylight Time, [EMAIL PROTECTED] writes: >At 04:29 PM 07/03/08, you wrote: >>Hi Guys >>does anyone out there happen to have a pinout on the accesory connecter >>on the back of the machine.... >> >>N9ex > >Google is your friend.... > >And the www.repeater-builder.com web site is as well.... > ><http://www.repeater-builder.com/kenwood/tkr-n20-notes.html> > >Mike WA6ILQ > > > > >Gas prices getting you down?
