Set your radio to 14.070 MHz upper sideband. Call somewhere between 300 and 2500 Hz up in the audio passband. You should call: KH6JF KH6JF de <Yourcall> <Yourcall>. If HF Voyager hears you, you will get a call back within 10-15 seconds. Remember, HFV is only putting out three watts.
Good luck and 73,
