Hi Paul, thank you very much. We are in our infancy and I had acess to these new units. The repeater will be used only for emergencies or sites needing communications. I have a much better idea where to go for the cor and discriminater now. I built a to go set up which has locks and I installed 2 fans just inches from the radios. I really appreciate the help. 73 russell w2rdt I look to the future because, that is where I will spend the rest of my life.

Also, develop a plan to keep the transmit radio's heatsink cooled, even in low power mode. But plunging ahead... Your controller can work with either COS ("carrier-operated switch") or derive that signal itself. If you can find COS in the Icom radio, you don't need discriminator audio, and can couple audio from anyplace handy, including the external speaker jack if it won't be accessible to passersby. You will need to lift one side of a capacitor on the controller board to use de-emphasized, non-discriminator audio. On the other hand, if you can provide the controller discriminator audio, you don't need COS - the controller will make its own. The CES docs actually seem to favor this approach. The 2200 doesn't provide the needed signals on its accessory connector, but there are leftover pins there you could use to get disciminator audio and COS out of the radio cleanly. Get the owners and service manuals, available through online search. 73, Paul, AE4KR ----- Original Message ----- >From: Russell >To: Repeater-Builder@ yahoogroups. com >Sent: Monday, March 15, 2010 11:33 PM >Subject: [Repeater-Builder] cor location in an ic-2200h > > >Hi, I am building a portable repeater for our ARES Club. >I have 2 Icom IC-2200H 2 mtr units, a ces rm-10 controller. >I am new at this building, and cannot decipher the info >given by the controller instructions. >It advises to use the radio cor connection and here is where I'm >stumped. >It also wants a connection at the output of the discriminater >circuit. >I have been a tech over 35 years, this issue is causing my teeth >to fall out, I already lost most of my hair. >I would really appreciate any help you might have. >73==Dan w2rdt > >BTW: I know these are not the best units to work with. >Financially right now, it is all we could afford. > >
