Icom IC-706 Transceiver: User Reviews, Mods, and Manuals
Find essential resources for the Icom IC-706, including user reviews, technical specifications, modifications, and service manuals.
The Icom IC-706 series transceivers have been popular among hams for their compact size and versatile operation across HF, VHF, and some UHF bands. Many operators appreciate the IC-706 for its portability, making it a common choice for mobile installations, field day operations, and even some QRP activities. Its ability to cover multiple bands in a small package has made it a go-to rig for many years, enabling QSOs from 160 meters up to 70 centimeters.
This category provides a wealth of information for IC-706 owners, from detailed user reviews and specifications to practical modifications. Hams can find resources for connecting accessories, such as the SGC-230 Smartuner, or building custom cables for contest logging software like TR-LOG. There are also technical notes and schematics for troubleshooting common issues, along with various modifications to expand transmit capabilities or improve VHF receive performance.

After years of reliable performance, a 26-year-old Icom 706MK2G exhibited an unusual deviation during FM transmission, with the actual frequency being 10kHz off from the displayed frequency. Additionally, the power meter showed a sharp dip during transmission. Upon investigation, it was discovered that the FM VCO voltage adjust variable had become dirty and sluggish over time. By adjusting the variable capacitor and cleaning it with switch cleaner, the issue was resolved, restoring stable power output and accurate frequency transmission. -
Icom 706MkIIG Filters, Make a narrow CW filter work in SSB for the digital modes -
Unlike older radios, the 706 uses only one crystal oscillator (called the Master Oscillator). All other frequencies in the radio (L.O., 3-4 I.F. stages, VFO, and CW-offset) are computer-derived from the Master Oscillator. This makes it relatively simple to frequency-align the radio, so that it agrees with the Frequency Display in all modes. -
