".....Das Hörstück „Knallfunken“ nutzt Miniaturblitze, um 
Funkenbildungen hörbar zu machen.
An den Blitzableitern der Funkstation Nauen empfängt Raviv Ganchrow 
Impulse weit entfernter Gewitter...."

(The radio play "spark-gap" used miniature flashes to make sparkling 
Raviv Ganchrow receives impulses from distant thunderstorms at the 
lightning conductors of the Nauen radio station.)

"......Knallfunken Circuitry

Knallfunken is a two-channel radiophonic work realized in collaboration 
with the Nauen shortwave transmitter in Brandenburg (the world's oldest 
continuously operating radio broadcaster) and Deutschlandfunk Kultur.

The earth and its atmosphere are a gigantic electrical habitat. 
Knallfunken is a literal circuit patched through diverse locales such as 
charged coils, sparking copper, tropical lightning, migratory cranes, 
swarming bees, 250 kW voltage, Central Asian & South American ground, 
New Zealand antennas, ionospheric refraction and autumn wind. 
Knallfunken revisits the miniaturized lightning of wireless telegraphy 
in order to listen to entanglements of its sparks. This piece sounds the 
material context of spark-gap transmissions through the site of 
long-range broadcasting (shortwave). ....."

"...Time Shift Fading

One recording in Knallfunken completed the journey from Germany to New 
Zealand eleven times, accumulating over 220,000 km of mileage in air and 
a similar distance again over Internet cables. As distances increased, 
time also began to have its say: it was discovered while working with 
the recordings that the received sounds no longer synced with their 
sources, the durations of the received audio was slightly altered, as 
though somewhere along the journeying even time began to warp.

Disappearing and reappearing signals are commonplace for long distance 
transmission, particularly shortwave radio. While bouncing through the 
atmosphere, signals project multiples of themselves that superimpose in 
constructive and destructive interference at the receiver. The result is 
a characteristic wavering as the signal fades in and out of static 
noise. During the first transmission from Nauen, an inadvertent gap in 
the signal was projected to the other side of the globe, due to a 
momentary shutdown of a transmitter. Knallfunken ends with this 
transmitter silence sent three skips to the east via ionosphere-Central 
Asia-ionosphere-Mongolia-ionosphere-New Zealand and rebroadcast three 
skips to the west via ionosphere-North 
Africa-ionosphere-Uruguay-ionosphere-New Zealand......"

"...Signal Labyrinth

The most prevalent current in the lightning rod ground recording from 
Nauen is the 50 cycle per second power mains hum, a familiar sound that 
household appliances sometimes emit mechanically. Mains hum in ground is 
an artifact of the networked national power grids, inducing charge into 
the earth's topsoil.

Ground electricity whose frequencies include everything from 
electro-chemical behavior in plant roots, to eleven-year sunspot cycles, 
also entangle with anthropogenic frequencies. Within the dense 
electromagnetic knot at Nauen there also appeared an unexplained, high 
intensity, periodic pulse strong enough to imprint directly into the 
recorder's circuitry when the recorder was placed on the ground. Sharp 
audible clicks in the rooftop drainage pipe at Nauen -- not unlike the 
sound of sintering from an oven -- seemed to match the electrical spike 
pattern in the ground below. The ominous drone from inside the drainpipe 
turned out to be a ringing version of an electrical transformer buzz 
emitted from behind a metal door, at ground level, at the back of the

"spark-gap"  is part of a trilogy that explores the physical-material 
aspects of wireless transmission.
Raviv Ganchrow, born in 1972 in the USA, lives as an artist and sound 
researcher in Amsterdam. In his texts and sound installations, he 
explores the relationship between sound, space and listening experience. 
Lecturer at the Institute of Sonology at the University of the Arts in 
The Hague.
