BASIC OPERATION 3 VFO description VFO is an abbreviation of Variable Frequency Oscil lator and traditionally refers to an oscillator The transceiver s VFO is somewhat different The VFO of the IC 775 acts like a computer s window and can show one frequency and one operating mode You can call up a desired frequency to the VFO with the keypad memo pad read switch see p 27 or the memory transfer switch see p 51 You can also change the frequency with the main dial and select the operating mode with the mode switches During dualwatch or split frequency operation SUB VFO appears You can change the SUB VFO fre quency with the sub dial While pushing XFC during split frequency operation you can also change the sub readout frequency with the keypad memo pad read or the memory transfer switch 21 295 MHz 28 025 MHz 7 001MHz The differences between the VFO mode and the memory mode VFO MODE 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 49 52 Each memory channel shows a frequency and oper ating 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 a VFO is selected from another band or the memory mode the last used frequency and oper ating mode for that VFO appear When the memory channel is selected from another memory channel or VFO mode the memorized fre quency and operating mode appear EXAMPLE EXAMPLE VFO is selected Memory channel 1 is selected USB inn nn 1 1 IUU UU USB VFO IU iu inn nn 1 1 IUU UU 1 ICH The frequency is changed USB VFO IU II 1 ICH USB ÎCH 1 ICH Г 1 TIUC nn I L IU UU MEMO in IUCH Memory channel 1 is selected again USB IJ 1Л nn IL J UU MEMO USB MEMO 1 nn nn IUU UU VFO is selected again u i 1 nn Idu uu Another memory channel is selected Memory mode is selected IU 1 1 1 ICH The frequency is changed USB IU 1Л l nn 1 1 IL U UU MEMO USB VFO I ICH Changed frequency 14 123 MHz appears inn nn tu 1 1 IUU UU MEMO 1 ICH Changed frequency 14 123 MHz does not appear and memorized frequency 14 000 MHz appears instead 24
