Follow the disassembly instructions. Remove the battery, then the back cover, then the RF shield can over the PA section. Use a non-conductive probe to avoid shorting adjacent pins.
One of the IC-705’s strengths is its support for modern digital modes. Integrated USB audio interfaces, CAT control, and network connectivity simplify running FT8, PSK31, and other modes from a laptop or tablet. The radio’s compatibility with popular logging and cluster-spotting tools streamlines contesting, DXing, and everyday on-air activity. Additionally, the radio supports Icom’s app ecosystem and third-party remote-control applications, allowing operators to control the transceiver from a smartphone or computer—an attractive feature for operators wanting to run stations remotely or use tablet-based interfaces during outdoor operations. icom ic705 service manual
