TH-G71A MODIFICATIONS --------------------- MARS/CAP MODIFICATION INFORMATION --------------------------------- It is illegal to operate outside the limits of your class license or permits. Modification procedure: 1. Remove the battery pack and antenna. 2. Open the SPKR/MIC dust cover, 3. Remove the three screws from the back panel ofthe transceiver. 4. CarefuIly lift up the bottom end of the back panel and pull the entire back pane I toward the bottom ofthe transceiver to clear the antenna connector from the top panel. Do not break the ribbon cable that connects the back panel PCB to the front case PCB. 5. Set the back panel to the left side of the front case. 6. At the bottom right side ofthe front case PCB you will see a green jumper wire.Cut this wire using a sharp pair of wire cutters. Be careful not to pull on the wire, simply cut it in half. 7. Assemble the transceiver by reversing the steps listed above. The transceiver will automatically reset when turned on, Transmit Operating Range: 142.000MHz - 151.995MHz, 420.000MHz - 449.995MHz BEYOND MARS MODIFICATION ------------------------ Modification procedure: 1. Remove the battery pack and antenna. 2. Open the SPKR/MIC dust cover. 3. Remove the three screws from the back panel ofthe transceiver. 4. Carefully lift up the bottom end of the back panel and pull the entire back panel toward the bottom of the transceiver to clear the antenna connector from the top panel. Do not break the ribbon cable that connects the back panel PCB to the front case PCB. 5. Set the back panel to the left side of the front case. 6. Locate and remove diodes D512 and D513 from the bottom right side of the front case PCB. If the green jumper wire has been cut, reconnect it at this time. 7. Assemble the transceiver by reversing the steps listed above. The transceiver will automatically reset when turned on. Transmit Operating Range: 136.000MHz-173.995MHz, 400.000MHz- 469.995MHz, Additional RX Capability: 320.000MHz- 399.99375MHz, 800.000MHz- 823.9875MHz, 849.000MHz- 868.9875MHz, 894.000MHz- 949.9875MHz NOTE: This change also allows the transceiver to access a previously suppressed menu, number 16. This menu allows the transceiver to switch between FM and AM in the 118MHz - 136.000MHz range. EXTENDED RECEIVER MODIFICATION ------------------------------ Modification procedure: 1.
