My first club is VFDB in Neustadt a.d. Weinstraße: DOK Z22.
I'm also organized in DARC as second DOK K13 Neustadt a. d. Weinstraße.
I own my license since Jan. 13 in 2012. My first call was DO8TX - novice licence.
This call I didn't use on HF, only for QSOs on the local 2m QRG.
My "A" licence I made in March 20 in 2012, nine weeks after the novice licence.
For training I own the exercise Call DN6TX.
Mein Leitspruch - (Zitat DL3PX Erhard):
"Das kannst Du tun - für Dich selbst ... "
(You may do this - for your self ... )
In den letzten Jahren hatte ich viele Begegnungen und Kontakte zu zahlreichen Funkamateuren.
Ich besuchte und engagierte mich in allerlei Gruppen und Clubs. Nicht alle dieser aktivitäten
und Bekanntschaften waren und endeten positiv. Daher besinne ich mich immer häufiger auf
diesen Ausspruch von Erhard. Damals ärgerte ich mich darüber. Heute denke ich leider,
dass das der beste Rat war, den ich jemals von eimen Funkamateur erhalten habe.
Also werde ich mich mehr auf mich selbst und meine kleine aber feine Station besinnen und
und dieses Hobby auf meinen Art leben. Wie, sieht man hier in den Bildern und liest es in den Texten.
The shack and home brew station-antennas:
For HF I am using a Kenwood TS-590 and for VHF / UHF a Kenwood TS-2000. The microphone I use is a swivel-mounted studio microphone.
The swivel-mounted mike is connected to the twin-foot-PTT under the desk. So I can work hands free with one mike running two TRXs.
The soundmixer is connected to the TRXs and my Hifi Amp so I can hear your voice out of the center speaker in front of my head - the perfect sound for absolutly low cost !
The white box left of the TS-590 is to tune the "Fuchs-Antennas" in the backyard.
Beneath the desk there are on the left side: PC, Printer, HiFi Amp.
And on the right side three power adapters 2 x 30 A and 1 x 15 A .
At night my shack looks like this!
This is my Fuchs-Circuit for 40m, 20m, 15m and 10m. The radiator has a length of 20m, so you´ll find the voltage maximum at these four bands at its ends.
The transformer has a gear ratio of 1:64 (2:16 turns) to transform the antennas resistace from aprox. 3200Ω down to 50Ω. The secondary coil has an inductance of 2µH and the capacitor a capacity range from 10pF up to 270pF. This makes possible to tune the circuit from 6.8 MHz up to 29MHz by driving the motor via remote from my shack.
As counterpoise I connected four shortened quater wave radials. The 0.05λ version of AA5TB didn´t work adequate on 40m.
And another Fuchs-Circuit for 80m monoband. It feeds a 32m long antenna from the end. The radiator is extendet by two coils of each 25µH like a very normal dipole.
The transformer has aggain a gear ratio of 1:64 (2:16 turns) and a secondary inductance of 15µH. The capacitor uses a capacity between 110pF and 150pF to tune the circuit over the complete 80m.
The SWR at both circuits is typicaly less than 1:1,3. Maximum input power is 750W PEP.
This is the third Fuchs-Circuit I build. It´s made for 60m and 30m. The capacitors range longs from 10pF up to nearly 200pF and the secondary coil has an inductance of 5µH. So this circuit contains 5MHz up to 20MHz.
As radiator I hung up a 26,5m wire witch would work on 5,3 MHz, 10,6 MHz, 21,2 MHz and 26,6 MHz. I use only 60m and 30m.
As couterpoisse I use two radials with a length of 13,5m for 60m and 7,3m for 30m.
Recently I used for 40m to 10m the Dutch HyEndFed 5 band antenna wich performed very well, but limited the usable power to 200W.
Now I decited build a new one and use it for 12m and 17m as a sloper with a trap. Tinkering the coax-trap was no problem and the transformer plays on this two bands, he rather wasn´t desinged for, without any problems.
Like in the past I hung up my wires as inverted-V by using my variable length mast with 10m hight. Four wires are used for nine Bands. At the top the 32m long wire for 80m extendet by two 25µH coils. in the middle the 20m wire for 40,20,15,10m. And below the 27m wire for 30,60m.
All theese inverted-V Antennas are feedet by the up shown Fuchs-circuits from their right ends.
The sloper thakes place above the mural up to the spire of the mast feedet by the up shown 1:64 transformer.
To replace the old nasty shelf wich contained my equipment I build this nice new cupboard. It´s made of two cupboards wicht are joint by a lighted shelf.
Now my loved nerd-things are stored tidily and my wife´s happy aggain ;-)
The Holiday Shack on the Island of Rügen in the Baltic Sea
This year we spend our holidays one more time on Rügen. We love this island.
We rented a small holiday apartment in "Klein Kubitz", a very small hicksville in the
western part of Rügen. 200m south from our apartment there is a small fishing port.
The perfect place to become QRV. If you like to see it, I changed the coordinates of my
QRZ account for the moment.
This is the latest version of my L-Match for to
short antennas for car use. It is designed to work with the MFJ-1979 5m telescope.
I call it "The Poisened Dwarf" (German: "Der Giftzwerg)
It is usable for 30m down to 80m and with the
coil on the outside of the tube on 160m.
Max. power 100W.
If you like to see more, follow this link to the homepage of our club (german):
It gets installed with three magnets on the roof of the car. The power and the couterpoise is connected by the PL-plug in the roof.
The grey cable is used to telecontrol it from inside the car.
The antenna is safely fixed with the magnets. Wind is not an issue, but storm is.
It is also not possible to drive with it, that is why I don't operate as "mobile".
The display of the TS-480 is attached via a vacuum cup to the windscreen. Two LED bars provide the light in the car. They are connected to the portable battery like the TRX (shown below).
Theese are the innards of the tube. A motorised coil and capasitor. It is the same as in the mobile antenna shown below, only with the 160m extention and distinctly miniaturized down to less than one foot.
This is the result of my last weekend - a footpoint match for the MFJ Big Stick for 60m.
As the other projects it´s also a L-Match for short antennas. The coil has an inductance of 17µH and the capacitor a capacity of 880pF. This circuit has an usable SWR-range (> 1:2) of aprox. 60kHz. It includes easily the 15kHz band section we are allowed to use in Germany.
A first test was very encouraging.
This is my small Shack in our nice little winter garden in our apartment on the island of Rügen in Wiek.
The TRX is a Kenwood TS-480 SAT with tuner and 100W.
With the small remote control I turn the antennas rotator.
Here you see the "huge" antenna system I used. It is a small and very light rotary dipol, made of two DV27s CB mobil antennas. It is tuned by setting in tuning sticks with different leght. So it works only on one band, but no tuner is needed (20m up to 10m).
The mast is a 12m DX Wire glass fiber mast. From the top end, I took away the last three thin mast elements. So it is strong enough to carry the dipol and the rotator. 9m hight is left.
Many thanks to Jürgen DK2PP who warmly recommendet this antenna to me. I have much fun with it.
A perfect holiday antenna !
The complete equipment finds place in a simple fishing rods bag.
The mast, the dipol elements, tuning sticks, ropes ,tent pegs, rotator, cables and so on ....
The Mobil Station
This is my car with the main antenna on top. It´s a telescope from MFJ with a total length of 5,15m.
Without the coil I use the antenna from 20m up to 10m. Then I simply vary the telescope length to a quater wave on each band. A tuner is not required.
For 30m, 40m, 60m, 80m and 160m (!) I pull it out completely and install the coil.
Here you can take a look into my car. I only operate while parking - not while driving.
So I install the display only when I´m operating. The display finds its place in the trunk, the wires and the microphone are in the armrest between the seats.
The Kenwood TS-480 SAT is under the drivers seat, together with the 13,8 V step up power booster (MFJ-4410). It is remoted by the amplifier contact of the TS480. It only works while transmitting and ensures always 100 Watts HF output!
To save the car battery, I can replug the power cable of the TS-480 to an external battery, like the small one on the picture, or the big portable battery by using XLR plugs.
The remote box you see on the seat is aslo used to remote the 80m coil.
The "coil" actually contains a small L-Match, made of the same coil (60 µH) as in my portable tuner and a radio capacitor (1nF). Both devices are driven by 12V DC motors.
This tuner allowes me to match the very short radiator directly in its footpiont down to a SWV of nearly 1:1.
The gain of the antenna on 40m ist very good. On 80m it´s still enough to have QSOs in Germany an the next european countries.
My equipment for portable use
This is the power unit if no power point is available:
- 45 Ah 12 Volt Battery
- Integrated automatic charger
- 13,8 V 25 A step up power device
- XLR and wire connctors
- 230 V 150 W AC output
It supplies the TRX for a long time and if necessary a laptop, a lamp, a soldering iron or something else.
This is the complete rig connected to the PC in day- and night view.
To the front panel you can connect the mike, the PC and a CW key or paddle.
You can turn the light on and off, switch between loudspeaker and headset and control the levels of the digi-interface and the mike.
To tune the loops I integrated a small electronic tuner.
The powersupply powers the Yaesu FT857D with max. 25 Amp. And 13,8 Volt. If it doesn´t work arelay automaticly switches over to the battery.
The Tuner shows the SWR and tunes most of diverse wires and antennas.
The connectionfield offers many plugs to connect antennas for HF/UHF, HF especially magnetic loops, symetric antennas and longwires.
I can power the station with 12Volt out of the battery shown up(XLR plug) and 230Volt using the integrated power adapter.
To power external equipment there are two connectors for 12Volt out – only from the power adapter.
The complete station with the big portable loop tested in the garden of my friend Hans.
I hope you enjoyed the tour and we will meet (again) on the bands.
73 and good DX s - Frank.
