Gauss Master Mods

The Gauss master is a very handy and useful tool but with  a little help  it
 can become  a  much more .   

Power switch modification. This simple change in the Gauss Master allows
the user to activate the unit in either the low or high sensitivity ranges and
not have to keep your hand on the meter to operate it. With this mod , it can be
turned on and laid  down to allow the user freedom for other tasks. 

Audio Output Modification.  This simple modification allows the user to use the
Gauss Master with an earphone ,   route the output to an audio recorder  to
record  signals found with the unit and route the Gauss Master output to a  computer
so that the output can be captured and analyzed with programs like Spectrogram .
  This mod  shows both the plain audio jack  installation and , if desired, include  an
 audio switch to quite the built in  speaker .

External antenna jack.     This simple change  adds an antenna jack on top of the Gauss Master to
access the  instrument input circuit.  With this mod , the user can outboard the stock antenna,
add different antennas or even use the basic meter circuit / vco  portions as an
inexpensive  " up converter "   or signal indicator circuit for other applications ( particularly
handy with " Stormwise " antenna rods and circuits ).

Other Gauss Master  modifications and additions.

Put your Gauss Master on steroids .   This  page shows you how to build a larger , more sensitive,
and much wider bandwidth   antenna to soup up your Gauss Master. ( needs the external  antenna
jack mod )   This is a " on the edge " mod   for  crowded and ( electrically )  dirty urban environments.
This mod will boost the sensitivity of   your  Gauss Master , but not too much.

Mega range antenna / sensors  using resonant ferrite rod technology  .  This page shows
 the construction and application of  ferrite rod sensors / antennas for a gauss master with the
 external  antenna mod. These are " strictly "  rural , non urban use sensors / antennas because
 they boost the Gauss Master to hyper sensitive levels. This section will also show how to use the
 " Stormwise " elf preamp  and an array of other preamp choices , to boost  the Gauss Master
sensitivity and  range even more.
