The Shack

Schack setup

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 Elecraft Dual paddle HexKey.

Soldering iron and screwdriver?
My workbench is upstairs and not worth taking photos off yet 🙂

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

The flag on the wall is a modern version of the Ravenbanner (Dane Broge) which was used by the Vikings during a raid.


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.


Messy CW?

2nd operator “DX”

Here’s why I sometimes mess around a bit in my CW.

He loves to push my hand while I’m sending CW and it happens that I get hold of his -…/.-/.-../.-../… instead of the paddles.
Then hell really breaks loose 😆 .

His name is “DX” and his motto is: “It is not necessary, but I need” and at the same time looking at his food bowl.

(Maybe he uses CAT Interface?)


Elecraft K-Line = K3 – P3 – KPA1500

KPA1500 – K3 -P3

This is my main station.

From left:
KPA1500 Amplifier – K3 Transceiver – P3 Panadapter.
Paddle = Elecraft Dual paddle HexKey.

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 ATU in the KPA1500.

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.

April 20, 2022: My KPA1500 Amplifier is out of order, sending smoke signal instead of HF, so my old KPA500/KAT500 is used until further notice.

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


Yaesu FT – 450D

FT-450D og MFJ-993B

Yaesu FT-450D og MFJ-993B ATU

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.


Racal RA17L

RACAL_RA17L

Racal RA17L receiver

Vintage tube communication receiver.

Freq. range: 0.5 through 30 MHz.


Extended/Inverted Fritzel FD4 Windom for 10 – 80m bands.


Extended wires for WARC and 15m bands.
Feed point up 12½ meters and the end points are up 4-6 meters.
As I live 30 meters from the coast line, the alu telescopic pole is equipped with lots of guying ropes.

April 18, 2022: The antenna is not very effective on 80m band.


Ground Plane for 6m band.

 

6m Ground Plane

Ground Plane antenna for 6m

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).


Vertical (for 60m, 80m and 160m bands).

MFJ-2990 vertical antenna

Used to be setup as inverted L antenna, but now changed to its originale design as vertical antenna as of April 19, 2022.

The antenna is 14 meters in hight and should cover 160m to 10m bands, but will mainly be used for 160, 80 and 60m 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 50 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.


Elecraft Dual Paddle HexKey

Elecraft Dual Paddle HexKey

Magnetic tension, just a dream! Elecraft, but made by Bencher.

Bencher BY-4 paddle.

Bencher BY-4 paddle

Perfect for my stiff fingers (hi).


Kent Twin TP1-B paddle

Kent TP1-B paddle

Very heavy and solid. Nice to use.


Vibroplex Original

Vibroplex Original

Including round vario arm.


Vibroplex Square Racer, Iambic paddles.

Vibroplex Square Racer

Magnetic tension, easy to ajust and use.


CWtouchkeyer, P1PAD, Iambic paddle.

CWtouchkeyer P1PAD

CWtouchkeyer P1PAD

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.


Great Northern Telegraph (GNT) handkeys

GNT hand keys

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.
