Radio Equipment : HF Transceivers : Icom IC-706

• Icom 706MkIIG Frequency Calibration - 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.

• Programming VHF/UHF Radios - Programming a new VHF/UHF radio usually proves to be a frustrating experience for most new amateur radio operators. A new radio must first be programmed for simplex and repeater operation before it can be used to communicate with local hams.
