Mal,

I am currently using an active e-probe antenna that was made by Jack
Smith at Clifton Laboratories. I asked him to custom modify this one
to be more sensitive than his standard version below 10 kHz, because I
plan to use it to try to receive a TA signal on your "dreamer's ba= nd".
He was able to make it quite sensitive down to 3 kHz at the expense of
using some parts with a lower voltage rating, so I have to be careful
not to short out the coax, etc. It is located about 15 meters from my
house and the base of the antenna is a mere 3 meters above ground, and
about 10 meters from the treeline.

My receiver is an Icom R75 (with CW filters), preceded by an LF
Converter of AMRAD design with a TXCO for frequency stability,
preceded by a 500 kHz low pass filter.

I also have a Wellbrook LFL1010, which is not currently in service,
but since this season is starting off so well, I may put it back up
for comparison with the e-probe.

Over the years, I have used several different antennas for LF
reception, including tuned longwires, homebrew e-probes that I
constructed, =A0homebrew loops, but I must say I am very impressed with
the Clifton Labs product, as well as the LFL1010, which I used last
season. Someday I would like to construct a large ferrite core
receiving antenna.

73,
