Scanning the "Parts List," he identified the failed SMD capacitor, a speck of ceramic no larger than a grain of pepper. The manual gave him the exact value: 10µF, 16V, 0603 package. : Sites like Mods
Before diving into the service manual's details, it's helpful to understand the radio it covers. The Icom IC-705 is a multimode HF/VHF/UHF portable transceiver, capable of operating on bands from 1.8 MHz up to 440 MHz. It's designed for field operations like SOTA (Summits On The Air) and POTA (Parks On The Air).
If you have a (e.g., "no power on," "screen flickering," "menu settings help"), please let me know, and I can guide you on what to check in the service manual.
This is arguably the most used section for advanced hams. Over time, internal crystal oscillators can drift due to aging and temperature fluctuations. The adjustment section provides a step-by-step guide to hooking the radio up to an external frequency counter, dummy load, and RF signal generator to bring the radio back to factory specification.

After any repair that involves replacing key components, the radio may need realignment. The service manual details these procedures, specifying which test points to use, what test equipment is required (e.g., a frequency counter, a service monitor), and the specific steps to bring the radio's performance back to factory specifications. This might include adjusting the PLL for proper frequency lock or calibrating the S-meter for accurate signal strength readings.
To officially obtain a copy of the IC-705 Service Manual, you typically need to contact an Icom authorized service center directly. You can find these contacts through Icom's main websites (e.g., icomjapan.com, icomamerica.com). In some cases, authorized distributors may provide the manual to certified technicians or upon providing proof of ownership for repair purposes.
