SETTING THE OPERATING FREQUENCYOPERATIONchange the operating frequency in 1 MHz steps, allowing very quick frequency excursions.This can be particularly helpful on the VHF and UHF bands.In step 2 above, it was mentioned that tuning in the “AM/FM/PKT” modes is accomplishedusing the SELECT knob. By default, the DIAL is disabled in these modes; if you wish toenable the DIAL in these modes, use Menu Mode No-004 [AM&FM DIAL]; see page 97.The main DIAL synthesizer’s tuning rate (the number of steps per rotation of theDIAL) can be adjusted using Menu Mode No-035 [DIAL STEP]. See page 102 fordetails.CHANGING THE DIAL SPEEDBy default, the FT-857 begins operation in the “fine tuning” mode for the main tuning dial.However, a faster tuning rate may be selected, for quick navigation up and down the band.To engage the “Fast Tuning” mode, just press the POWER switch momentarily while thetransceiver is on. You will observe a small “ ” icon inPOWERthe bottom right-hand corner of the LCD, and as yourotate the main tuning dial you will notice that the tuningrate has increased significantly. Press the POWERswitch momentarily once more to return to the “SlowTuning” mode (the small “ ” will disappear).STACKED VFO SYSTEMPress the [FUNC] key momentarily, then rotate the SELECT knob, as needed, until MultiFunction Row “a” [A/B, A=B, SPL] appears on the display.Now press the [A](A/B) key to toggle between the “A” and “B” VFOs. There are two suchVFOs provided on each Amateur band, so you may set VFO-A to the CW sub-band, andVFO-B to the SSB sub-band, if you like. The operating mode will be preserved, along withthe frequency information, on each VFO.When changing bands on either the “A” or “B” VFO, the two VFOs do not changebands together. This facilitates split-band operation, such as on FM satellites.FT-857D Operating Manual37
