4 FREQUENCY SETTING s VFO description VFO is an abbreviation of Variable Frequency Oscillator, and traditionally refers to an oscillator. The IC-718 VFO can store a frequency and an operating mode. You can call up a desired frequency to the VFO with the keypad or the memory transfer function (see p. 37). You can also change the frequency with the tuning dial and select the operating mode with the [MODE] switch or call up previously accessed frequency and modes with the band stacking register (p. 18). The IC-718 has two VFOs, specially suited for split frequency opration. The VFOs are called VFO A and VFO B. You can call up the desired VFO. • Differences between VFO mode and memory mode VFO MODE Each VFO shows a frequency and operating mode. If the frequency or operating mode is changed, the VFO automatically memorizes the new frequency or new operating mode. MEMORY MODE (pgs. 35-38) Each memory channel shows a frequency and operating mode like a VFO. Even if the frequency or mode is changed, the memory channel does not memorize the new frequency or operating mode. When the VFO is selected from another VFO or memory mode, the last-used frequency and operating mode for that VFO appears. When the memory channel is selected from another memory channel or VFO mode, the memorized frequency and operating mode appear. [EXAMPLE] VFO is selected. [EXAMPLE] Memory channel 1 is selected. The frequency is changed. The frequency is changed. Memory mode is selected. Another memory channel is selected. VFO is selected again. Memory channel 1 is selected again. Changed frequency (14.123 MHz) appears. Changed frequency (14.123 MHz) does not appear and memorized frequency (14.100 MHz) appears instead. 16
