IC24AT.9 The IC-24AT can also function as a Mini Repeater transmitting on the UHF band while simultaneously receiving on the VHF band, or vice versa. This procedure requires both a small hardware as well as a software modification, and is performed as follows; o Locate diode D14. It is located adjacent to the location for diode D13 (see above procedure). Clip or remove it. o To enable Mini Repeater operation 1. Push and hold the "Function" key and then the "C" key. 2. Push and hold the "Function" key and then the "5" key and the "D" key. o To cancel the Mini Repeater operation, push and hold the "Function" key and then push the "D" key. The above modifications provided the following capabilities with my particular unit. FREQUENCY COVERAGE (VHF) RECEIVE TRANSMIT 74.9 Mhz. - 127.9 Mhz. OFF 138.0 Mhz. - 168.0 MHz. 138.0 Mhz. - 159.0 Mhz. 174.1 Mhz. - 189.69 Mhz. OFF 200.0 Mhz. - 287.22 Mhz. OFF 310.0 Mhz. - 349.0 Mhz. OFF (UHF) 355.0 Mhz. - 409.98 Mhz. OFF 412.37 Mhz. - 498.0 Mhz. 410.5 Mhz. - 470.0 Mhz. 792.85 Mhz. - 966.66 Mhz. OFF Receive sensitivity throughout both of the Ham bands was better than .5 of a microvolt. Sensitivity in the 200 Mhz. range was a disappointing 1 millivolt and in the 800 Mhz. band a good .7 of a microvolt. Remember, while the unit will receive on those frequencies, it is illegal to monitor cellular telephone communications. Good luck with your unit. "73" Joe Taylor, W9JO
