Sorry, but that is not correct. Amateur repeaters (just like operators) are required to ID at the beginning of a transmission sequence, every 10 minutes during, and at the end of the transmission sequence. If no further traffic is repeated, the machine may then sit silent until the next sequence begins. Normally, when a ham repeater is first keyed up, or "cerchuncked", it will send an ID immediately. If no one then uses the machine, it will ID again in 10 minutes, then stay quiet. If someone does use the machine, it will ID every 10 minutes during the conversation. If the conversation ends after 27 minutes, then after an additional 3 minutes, the machine will send the final ID at the 30 minute time slot, then be silent until keyed up again. For GMRS, there is nothing in the rules that require a repeater to ID, but the operators must. Just for good measure, most repeater operators ID their machines as well. I have mine set up just like a ham repeater, except the ID timer is set to 15 minutes rather than 10 minutes. It stays silent until I key it up, then it will ID after the first transmission. If I talk for 3 minutes, then sign off, it will stay quiet for 12 minutes, then send the final ID before going back quiet. By the way, I use Bridgecom repeaters as you mentioned, and they already have this Morse ID function built-in. At set-up, you type in your call sign, and set the ID timer for 10 or 15 minute intervals.
