The VX-8R’s frequency synthesizer provides the option of utilizing tuning steps of 5, 6.25,
8.33, 9, 10, 12.5, 15, 20, 25, 50, 100, and 200 kHz per step. The VX-8R is set up at the
factory with different default steps for each operating band which are probably satisfactory
for most operation. However, if you need to change the channel step increments, the proce-
dure to do so is very easy.
1. Press the key, then press the key on the left side of the radio. This provides a
“Short-cut” to Set Mode Item 96: STEP FREQUENCY 96: STEP FREQUENCY 96: STEP FREQUENCY 96: STEP FREQUENCY 96: STEP FREQUENCY .
2. Rotate the DIAL knob to select the desired step size.
3. Press the PTT switch to save the new setting and return to
normal operation.
1) 9 kHz steps are available only when receiving on the BC band.
2) 8.33 kHz steps are available only when receiving on the Air band.
3) While operating on the BC band, you may only select channel steps of 9
kHz or 10 kHz; the other step selections are disabled.
4) 5 kHz steps are not available for use on 250 - 300 MHz, nor above 580 MHz.

The VX-8R provides for automatic mode changing when
the radio is tuned to different operating frequencies. How-
ever, should an unusual receiving situation arise in which
you need to change to a different receiving mode, just press
the
key. The receiving modes available are:
AUTO AUTO AUTO AUTO AUTO : The receive mode is automatically set accord-
ing to the default values for the selected fre-
quency range
NFM NFM NFM NFM NFM : Narrow-bandwidth FM (used for voice communication)
WFM WFM WFM WFM WFM : Wide-bandwidth FM (used for high-fidelity broadcasting)
AM AM AM AM AM : Amplitude Modulation
1) The “WFM” mode cannot be selected on the “A-Band”.
2) Unless you have a compelling reason to do so, leave the Automatic Mode
Selection feature on in order to save time and trouble when changing bands.
If you make a mode change for a particular frequency or station, you can always store
that one channel into memory, as the mode setting will be memorized along with the
frequency information.
