Kenwood TH-F6/F7 - UHF band MOSFET fried - need component location info
Hi,
Can anyone help me? I seem to have fried the MOSFET that drives the UHF band (265 - 600MHz)receive circuit - I accidently transmited on 446Mhz with high power on my extended Tx modded HT. My TH-F7 is fine on the LF bands and on VHF but it is now very deaf on UHF - 430MHz. I have read elsewhere that the transistor can be replaced with a CF739 and I have managed to obtain a couple of these devices. My problem is - how do I locate this transistor? Looking at the schematic it looks like Q62 is the device I need to change. Can anyone show me on a diagram or photo where this transistor is on the PCB? The TH-F6 and TH-F7 are basically the same so info for the TH-F6 will probably help me. Many thanks in advance - I'm sure somebody must have this info but I have not managed to find it by myself. 73 de Stuart G3SNA |
