buy her a new computer for a wedding gift?

how are the speakers driven?  i have a pair of cheap radio shack 
speakers driven off a soundblaster board.  i had allsorts of rf
problems until i figured out that i should get rid of the power
cube and instead of using the internal amps in the speakers i run
them off the amplified output from the soundblaster.  no caps, no
toroids, and no more rf.

In response to the many who requested this information:

Several weeks ago I received a catalog from Titanex - in 
German.  Lucky thing my secretary is German and is 
excellent at technical translation!

So here's the deal.  Titanex makes a wide variety of antennas
including HF Yagis, Cubical Quads, Verticals, and HF log 
periodics.  All looked to be very well designed and made.  
For instance, they make a full size 3 element 40 yagi and
a 13 element 7-30 mhz log periodic.

There is no US distributor but they will ship from the factory
direct to the US.

The antenna that particularly interested me is the V 160 E,
which is a 26 meter high vertical for 160, 80, and 40.  It comes
with or without a 3KW remote antenna tuner.  The antenna is
very lightweight at 7.5 kg and is guyed at four heights. Guys
are included.  There is an expedition version (the V160 E) and
a non-portable version (the V160).  Principle difference is the
shipping length 3.1 meters for the E and 6.1 meters for the 
standard unit.  Unfortunately 3.1 meters is too long for me to
take to Ambergris Caye, Belize.  2 meters would work fine....
sigh.....

Pricing is high for this unit but pricing for their other antennas 
seems in line with the industry.  

Pricing to me - and this may be a special case - landed in 
Los Angeles, including air freight is $1366 without tuning
box, $1919 with the remote 3KW tuner - which you need for
160 meter operation.

They were quick to respond to my query.

Good luck in the contests,
