QSL: The River Neckar
I live here at the river Neckar
 
 
 
QSL2: Albino Asio otus
Three young long eared owls. One is normal, one nearly pure white and one is a real albino owl
 
 
 
Albino Waldohreulen
All pictures are taken from my balcony. Owls on a rainy afternoon on a tree in the garden of my neighbour.
 
 
 
PSK31 portable
IC703 and a NUE-PSK-Modem in a suitcase on a island in the river neckar
 
 
 
CW and PSK
IC703 and a keyboard for both CW and PSK in a suitcase on a island in the river neckar
 
 
 
Up&Outer-Antenna
for 20 and 30m outdoor
Easy to build up, high-performance antenna for field days
 
 
 
Windom-Antenna
for 80,40,30
Multi-Band-Windom-Antennea with arms and capacitor
 
 
 
Inverted Delta Loop
also called Nabla-Loop
for 80 40 30 ... M
My garden is too small for a full Delta Loop of size of 84M, with this additional leg, I can send on 80M
 
 
 
Delta loop with
Loading coils
and Balun 1:3
for 160,80,..M
To enjoy the calm reception of a loop also on 80M, I build a loop with load coils
 
 
 
Shortened Vertical Loop
for 40, 80, or
160-Meter DX
My garden is too small for a full size Delta Loop, but this is a small antenna for 40 Meter DX with a low radiation angle
 
 
 
Hybrid-Loop:
Magnetic Loop for 160M,
Dipol for 80M, 40M ..
A Loop Antenna, it was my best antenna.
 
 
 
Multiband Inverted-L Antenna
Vertical Antenna for 160M, 80M and 40M with only one trap
 
 
 
My old Antenna for 160..6M
Indoor in the Attic
Diamond(R) W-8010 5-Band-Antenna plus a 160,30,17 and 12 meter arm
w/o WARC  Side view
 
 
 
How to build a Fan-Dipole
in the Attic
Construction tips for a fan dipole antenna in an attic
 
 
 
160M Magnetic Loop
Receiving Antenna
Not a real Magnetic Loop, because the wire of the outer loop is too long. Frequency set fix to 1825 kc, so no extra capacitor is needed. Inner Loop is shielded against noise, with shield splitted in the middle
 
 
 
CW Bandpass Filter
with PIC Decoder
Decoding Capability as good as CW Skimmer, in Contests even better. Much better than the internal decoder of my K3-transceiver
 
 
 
CW Decoder with PIC
CW Decoder 4 to 40 wpm with Audio Bessel Bandpass Filter and PIC16, works fine
Box Inside Schematic
 
 
 
Morse Decoder with PIC
CW Decoder with more and smaller filters and an audio amplifier
Box Inside Schematic
 
 
 
Norton Amplifiers
For RG58 burried in the lawn working as receiving antenna
For a shielded receiving loop in a bush in the garden
 
 
 
Small Vertical for Receiving
About 7 meters high
 
 
 
Receiving Magnetic Loops
in Parallel
Four small magnetic loops in parallel for high signal strength with keeping the small diameter
In the wiring box
2 Loops with BLUE WAVE
 
 
 
EWE Receive Antenna
EWE-Antenne with 820 Ohm
 
 
 
Common Mode Choke for
Receiving Antennas
feed line common-mode choke isolation for reducing noise at receiving antennas
 
 
 
Wideband Receiving Antenna with
Four Small Magnetic Loops and
Preamplifier MegaLoop FX
4 Small Wideband Magnetic Loops with preamplifier.
 
 
 
Wideband Receiving with
Parallel Dual-Loop
