Rigs & Antennas

 

 

“Antennas should be heard, not seen”

 


 

The Shack setup

The Shack

The shack setup.

The computer is for logging only as well as lookups in QRZ.COM a. o. The computer will never be a part of the radiocommunication whatsoever.

On the table you can my Kent Twin paddles TP1-B. To the right my Vibroplex Original.

Soldering iron and screwdriver?
My workbench is in the opposite corner of the shack and is really not worth taking photographs off yet 🙂

CW on a PC? Never, I want to have fun.

View over the Baltic Sea (looking towards NE) from my shack window.

On the flagpoles, left: The Bornholm Island regional flag and right: The Danish flag “Dannebrog”, which celebrates its 800th anniversary June 15, 2019.

As you can see, it was a nice spring day with a calm wind from N/NW, sunny with abt. 8 dgrs. C.


Elecraft K-Line (K3-P3-KPA500-KAT500)

Elecraft K-Line
K3 – P3 – KPA500 – KAT500

This is my main station.

Barefoot operation:

The radio is equipted with internal ATU, Sub-receiver and 100 Watt output.
In most cases the internal ATU is bypassed and I will use the KAT500 external ATU.

The P3, Panadapter, which gives me an excelent wiew over the band I’m working on.

The radio has 11 bands, 6 m through 160 m. The optional 2 m module is not implemented in my radio.

Power Amplifier operation:

KPA500 amplifier, output depended of band and antenna, but are usally between 350 and 450 Watt. KAT500 external ATU.

Transceiver/Panadapter/KAT500 PSU:
Diamond GSV-3000, 30A at 13.8VDC (Not shown).

Yaesu FT – 450D

Are used as my spare station and non-home-QTH activities, like fielddays, ILLW etc.

Bands:  160-10 m, incl. WARC and 60 m bands.

Output power: 100 Watt.


RACAL_RA17L

Racal RA17L receiver

Racal RA17L

Vintage tube communication receiver.

Freq. range: 0.5 through 30 MHz.

Carolina Windom antenna.

It’s a model CW80 (10-80m bands).

The antenna also covers the WARC bands. All models need an antenna tuner (ATU).

The antenna setup is inverted V, NE/SW. The feed point are up about 12 meters and both ends are up about 4 meters.
But as my estate is located on a slope, the end of the long leg is about 5 meters lower than the end of the short leg, relative to the horizontal plane.

The vertical element of the antenna is angled about 30 degress away from my alu-pole, according to the manufacturer’s instructions.

The antenna should cover all bands from 80m to 10m, but I have some SWR problems mainly on 10m, so for that band I use my GP antenna.

Ground Plane

The antenna is an old antenna for 2 meter band, but modified to 6 meter band. The antenna can also be used on the 10 meter band.

The antenna is installed on the Chimney, abt. 8 meters up from ground (15 meter ASL).

When used on 10m band I will usally use my Carolina Windom as RX antenna, as this antenna has better reception capabillity than the GP.

Inverted L

The inverted L antenna is only used for 160m operation, but can be used on 80m and 40m too.

The antenna is installed with the feed point at ground level and with 20 burried radials of different lengths. Due to the lack of space, the radials are not evenly distributed, but mostly in the western and southwestern direction.

The wire is about 40 meters long, 6 meter vertical (electric length 16 meters) and 24 meters horisontal sloping down to abt. 3 meters.

The vertical part is made of a “Springy spring” (a toy for children). If you stretch the spring it’s abt. 16 meters long (22 cm in circumference and 75 windings = 16.5 meters).

The horisontal wire is a little to long, but will be corrected during the summer/fall.


Bencher BY-4 paddle

Bencher BY-4 paddle.

Perfect for my stiff fingers (hi).

My first choice of paddles.

 

 

Kent TP1-B paddle

Kent TP1-B paddle

Very heavy and solid. Nice to use.

Vibroplex Original

Vibroplex Original

Including round vario arm.

 

Vibroplex Vibrokeyer

Vibroplex Vibrokeyer

My first bug.

Single lever and also nice to use.

Vibroplex Square Racer

Vibroplex Square Racer,

Iambic paddles.

Magnetic tension, easy to ajust and use.

DSC01087

CWtouchkeyer

CWtouchkeyer, P1PAD
Iambic paddle.

No moving parts or contacts, you just have to touch the paddles.

You have to pratice a lot, not easy to use. It CAN be very sensitive to HF on some bands, but else nice to use.

Is available in many configurations, with and without internal keyer Electronics. My model have only the paddle Electronics and I use the internal keyer in the K3 transceiver.

GNT hand keys

Great Northern Telegraph (GNT) handkeys

Two different models.

The black one is similar to the one I – for many years ago – learned the art of CW.

My arthritis wrists do not allow them to be used daily, but they are touched once in a while.
