Rigs & Antennas

 

 

“Antennas should be heard, not seen”

 


 

Shack August 2020

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 any radiocommunication whatsoever.

On the table you can see my Bencher BY-4 and Kent Twin TP1-B paddles.

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.

 


Shack window view

Shack window view

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

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:

On February 12, 2019 I got my first external PA-unit ever. Since 1974 and until that date I have worked with 100 Watt. From 1973 to 1974 QRP with 5 Watt.

KPA500 amplifier, output depended of band and antenna, but are usally abt. 400 Watt. KAT500 external ATU.

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

 

 


FT-450D og MFJ-993B

Yaesu FT-450D og MFJ-993B ATU

Yaesu FT – 450D

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

Bands:  160-6m, incl. WARC and 60m bands.

Output power: 100 Watt (max.).


RACAL_RA17L

Racal RA17L receiver

Racal RA17L

Vintage tube communication receiver.

Freq. range: 0.5 through 30 MHz.

 


 

Carolina Windom

Carolina Windom (here inverted V setup)

Carolina Windom antenna.

It’s a model CW80 (10-80m bands).

The antenna also covers the WARC and 60m bands.
All models need an antenna tuner (ATU).

The antenna setup is close to be flat-top, wires pointing NE/SW. The feed point and the end of the long leg are up about 12 meters and the end of the short leg are up about 6 meters.
But as my QTH is located on a slope both ends are apx. in the same height 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.

 


 

6m Ground Plane

Ground Plane antenna for 6m

Ground Plane

The antenna is an old antenna for 2 meter band, but modified to 6 meter band.

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

The flag is “Bornholmerflaget” (Bornholm Island regional flag).

 


Inverted L antenna

Inverted L

I use the 5 lower sections (of total 8 sections) of a MFJ-2990 vertical antenna. The remaining 3 top sections are made as a horizontal wire. The wire are made much longer than the 3 sections, because that produce a better SWR on the 160m band.

The antenna is set up exclusively for the 160m band, but can be used for all HF bands.

The antenna is self-supporting, but since my QTH are very close to the coast, sometimes with very strong winter storms, the antenna are equipped with guying ropes.

The antenna is installed with the feed point at ground level (up 30 cm) 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.

 

 


Bencher BY-4 paddle

Bencher BY-4 paddle.

Perfect for my stiff fingers (hi).

My first choice of paddles.

 

 

Kent TP1-B paddle

Kent Twin 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 (model 605) 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.
