Yaesu VX-8GR Cheat Sheet

  • Volume - Hold_Vol + Turn_knob
  • Squelch - FW, Mon, Turn_knob, FW, Mon
  • MONI/T.Call = Suppress squelch
  • F/W = Alt (i.e. access the other function of the keypad)
  • Change transmit power = F/W + Atom
  • Check power level = L1/L2/L3/Hi in the lower-left on the display

Notes:
  • "Tap" means a brief button press.
  • "Hold" means to hold the button about 1 second, until its secondary function activates.
  • "Turn" means to turn the only knob on the radio. (Since the knob is the only thing that turns, I don't say "Turn knob."
  • "++" means to see procedure defined elsewhere on this page.
  • "x+y" means "at same time"; "x,y" means "sequentially"
  • There's a key in the lower left, with TX/PO as its alternate function, that looks like an atom with revolving electrons to me. I call this the 'atom' key.


I hope this helps otherslike me that are just getting their feet wet in APRS
