I am using a geared motorised volume control motor from an old stereo amplifier to remote drive the large ganged tuning capacitor using an additional shaft geared reduction drive coupling device to slow down the speed of turning the capacitor, choosing a lower voltage to drive the motor with will also slow down the turning which will allow more accurate tuning or peaking of the loop.
Once mine is finished then I will post photos of all the important parts for all to see.
Best regards!

Try that one.

Very nice! Hey, I wonder if you could use a servo to tune the loop
remotely. Or one of those surplus motor driven potentiometers,
linked to the tuning cap shaft.

Steve,

I haven't contacted him about the DFD2 not working yet. I really
should though since the counter worked fairly well during the time it
was working. Not as well as my Oak Hills DD-1 but fairly well anyway.

I may just be overly picky when it comes to PC board quality. I've
built several Small Wonder Labs kits, a couple from Oak Hills and a
couple from the AMQrp club. All with nice fiberglass boards, solder
masking, plated through holes, etc. That's kinda spoiled me <G>

Thankyou Bear for the very detailed picture of your QTH and surrounding area, let's hope you don't get a tidal wave. Perhaps being so close to sea level helps connects your antennas or ground plains to the sea itself, we all know how good the sea is (or large bodies of water) at being terrific gound plains for transmitting and receiving HF signals, maybe this is why the Geomantic Spiral works so well on the ground.
Would be interesting to hear about this fascinating antenna at other different locations and altitudes (above or away from the sea). I live close to the sea which is around 3 miles to the south east and my QTH would be around one to two hundred feet above the sea. I wonder how this type of antenna would work for someone living in the mountains?
Should be very interesting days ahead as this antenna is developed and experimented with by more people.
Thanks again Bear and best regards!

Michael,

My QTH is a typical(?) urban environment. I live on the ground floor
of a 3-story apartment building. My apartment is in the roughly NE
corner. The ground elevation here is about 10' above sea level (I'm
in a tidal wave inundation area). There is a large 25 story building
only 50' to the North of me and several other tall buildings
surrounding me within a 1/4 mile radius. I am also surrounded on all
sides by elevated electrical, telephone and cable TV lines within a
radius of 100 to 200'. There is a small park next to my building on
the East and Southeast side. Perhaps 1 acre or a little less in area.
There are a couple of very large, old Ficus trees growing there as
well as some other smaller trees. My lanai area is only about 8' wide
by 20' long. There is a Mock Orange hedge some 8' tall between me and
the park.

My 23' vertical antenna is located at the NE corner of the building
and is only 2' from the side of the building. The lower section of it
is 18" away from a 6' high chain-link fence. There are 3 elevated 24'
radials connected to it as well as 1 24' buried radial. My loop
antenna is on the roof of the apartment house and connected through a
100' RG-58 cable run. Currently the loop is acting intermittently. I
think I have a loose connection up there that I will need to fix.

The Geomantic Spiral is under the bricks in the barbeque area of the
lanai about 3' from the side of the building.

This is obviously not a "dream" DX location!! Despite that I have
been able to make some pretty decent contacts with QRP operation on
the 30 and 20 meter ham bands around the Pacific and into South
America while running only 2 watts output. The plus side to this
location is that it provides me the opportunity to play with and
develop various types of antennas that will be effective in a "less
than ideal" kind of environment.

Locked 4 foot loop antenna and other antenna projects.

Adam Ebel
 

I am thinking about getting some wood , and build a 4 foot
loop, cause my broadband loop has got the winding less than 10
turns. Are there any other projects that I should try out to
dramatically improve my AM and LW reception? I will take notes.

Adam Ebel Thanks.
Locked Another Interesting Compact Antenna

 

There's another compact antenna with its own new group here on Yahoo
at...

<>

There isn't much there yet but a few pictures and a link to the
owner's home page. The antenna he describes is a form of ground
independent coaxial monopole helically wound on a plastic flowerpot.
It is tuneable by adding a variable capacitor across the far end of
the antenna. There is a photo illustrating it.

Throw an arrangement of plastic flowers in the pot and you have a
nice attractive and very stealthy antenna. Now who could possibly
object to something like that on 12th floor veranda in a condo?
