TM742.2 From: VE2PAL@VE2PAK.PQ.CAN.NA VE2PAL/TPK 1.81 Msg #:17 Le 31/05/93 a 8:27Z Subject: TM-742/942 Beyond Mars/CAP Mod. Guide Procedure: 1. Detach the front panel from the main chassis. 2. Remove the bottom cover of the transceiver by removing the 4 screws on the bottom of the cover and loosening the 4 screws on the side of the unit. 3. Orient the radio so the bottom is up and the front panel area is near your chest. Near the front panel area you will find a large board, this is the control unit. 4. Remove the chip resistors "Y" noted in the diagram below, and reinstall them in position "Z" as shown. 5. Reinstall the bottom cover of the transceiver and reattach the front panel. 6. Reset the microprocessor. Press and hold the MR key while the power is switched on. Then release the MR key. This will erase all operator programmed data. 7. The frequency range after modification will be: 28 Mhz Band: RX: 18.0 thru 54.0 Mhz TX: 26.0 thru 45.0 Mhz 50 Mhz Band: RX: 40.0 thru 90.0 Mhz TX: 46.0 thru 76.0 Mhz 144 Mhz Band: TX: 136.0 thru 174.0 Mhz 220 Mhz Band: RX: 215.0 thru 260.0 Mhz TX: 215.0 thru 235.0 Mhz 440 Mhz Band: TX: 410.0 thru 470.0 Mhz 1.2 Ghz Band RX/TX: 1100.0 thru 1400.0 Mhz Please note that these are theoretical ranges only. Not all radios will be capable of tuning the entire range.
