<H1>9 kHz Receiving Equipment</H1>
<P><FONT face=Tahoma><STRONG>Jim M0BMU</STRONG> has produced a neat loop/preamp
design suitable for listening to Radio Amateurs operating around
9kHz.</FONT></P>
<P><FONT face=Tahoma>Interest in these frequencies has been growing recently and
several UK Radio Amateurs have applied to Ofcom for NoV's to transmit at these
frequencies. The<STRONG> wavelength of 9 kHz is about <U>33km</U></STRONG> so
practical antennas certainly present some challenges.</FONT></P>
<P><FONT face=Tahoma>Already signals <STRONG>have received at distances
exceeding 800 km</STRONG> and it's surely just a matter of time <STRONG>before
an Amateur Radio 9kHz signal gets across the Atlantic</STRONG>!</FONT></P>
<P><FONT face=Tahoma>The loop/preamp design by Jim M0BMU has sufficiently low
noise to provide a state-of-the-art receiver for this band when used with the
many excellent software based VLF receivers such as Winrad and Spectrum
Lab.</FONT></P>
