A 2.1&nbsp;kHz allocation, the [[136 kHz]] band (135.7&nbsp;kHz to 137.8&nbsp;kHz), is available to [[amateur radio]] operators in some countries in Europe, New Zealand and French overseas dependencies. The world record distance for a two-way contact is over 10,000&nbsp;km from near [[Vladivostok]] to [[New Zealand]].<ref name="ZLUA0">{{cite web|publisher=The World of LF |url=http://www.wireless.org.uk/newspic92.htm |title=QSO ZL/UA0 on 136 kHz}}</ref> As well as conventional [[Morse code]] many operators use very slow computer controlled Morse code or specialized digital communications modes. A proposal at the WRC-07 [[World Radiocommunication Conference]] aims to make this a worldwide amateur radio allocation.
