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.

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.

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?

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.

 

In September 2023, I also got a young black and white male cat, possibly abandoned in a holiday home area nearby.
He is incredibly lively and is also occasionally the cause of a bit of QRM in the shack 🙂

His name is Taiji because of his fur colors. Taiji is the Chinese word for the sign, what we in the West call Yin & Yang.
He has now been neutered and ear tagged and has become a part of the my family.
Meow!, Meow!


Elecraft new K-Line = K4D + KPA1500

From left:
Boya mic. on Kenwood modfied MC-50 stand, Elecraft K4D Transceiver, Elecraft Dual Paddle HexKey and KPA1500 Amplifier (RF-deck).
The KPA1500 PSU are under the desk and not shown.
The K4D, amplifier and ATU can be controlled on the PC with the Win4K4Suite application.

Barefoot operation:
The K4D radio has Sub-receiver and 100 Watt output, but no internal ATU.
I will use the ATU in the KPA1500, both barefoot’d and amplified.

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.
Max. legal limit in OZ-land are 1 kW. On some bands much less.
Depending on the band, my output will be between 500 and 1000 Watt. On 60m limited to abt. 100-150 Watt.

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

Electronic log:
Ham Radio Deluxe (HRD), in my opinion the best logging application with full screen size window and clear fields and text, which is UFB for my bad eyes.
No small windows and rubbed text. The “Rig control server” is replaced with Win4K4Suite, where I can control both radio, amplifiers and ATU’s.

 


Racal RA17L

RACAL_RA17L
Racal RA17L receiver
Vintage tube communication receiver.

Freq. range: 0.5 through 30 MHz.


MFJ-2990 Vertical for 10-80m bands.

 

MFJ-2990 Vertical

Covers all bands from 80m to 6m. Should also cover 160m, but can’t tune it on 160m.

The antenna is self-supported, 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.


Homemade Longwire for 160m band.

Homemade 160m LW

 

39 meters longwire (homemade), where the first 10 meters going almost straight up and the rest (29 m) are sloping down to a high of abt. 5 meters.

The antenna has SWR 1:1.2 without ATU, so it’s cut bullseye. It picks up a lot of noise on 160m, so I use my vertical as RX antenna on 160m.

On the other hand the LW is great as RX antenna on 80m band. (Less noise).

As I live close to the Baltic Sea (30 meters) the pole is equipped with many guy-wires..


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.
