Welcome to the German ATV

(Amateur Television) Homepage


engATV activities in the "Niederrhein" area, Germany

The project around the PI6ANH ATV-Repeater in Arnhem (The Netherlands)
is a cooperation of German and Dutch Amateur Radio Operators (aka "HAMs").
We hereby want to introduce ourselves and would like to share experience and discuss
technical developments on Amateur Television - related subjects. Your articles
are most welcome and will be built in, if you wish! After a little time
of construction, we shall introduce circuit designs fortransmitters, receivers,
antennas and other little tools. The emphasis will be on themes around FM-ATV
(Frequency Modulation) on the frequencies of 1.2 GHz, 2.4 GHz and 10 GHz,
but AM-modulation and 70cm won't be neglected.

gerATV Aktivitäten am Niederrhein

Das ATV-Relais Projekt PI6ANH in Arnhem (Holland) ist aus der Zusammenarbeit deutscher und
niederländischer Funkamateure entstanden. Wir wollen uns und unsere Aktivitäten vorstellen...
Gerne würden wir auch mit anderen ATV-Freunden Erfahrungen austauschen und neue
technische Entwicklungen im ATV-Bereich diskutieren. Eure Beiträge dazu sind
sehr willkommen und werden auf Wunsch auch hier eingebaut. Nach einer Aufbauphase
sollen hier Schaltungsentwürfe für z.B. Sender, Empfänger, Antennen
sowie anderes nützliches ATV-Zubehör vorgestellt werden. Besonderer
Schwerpunkt wird dabei auf der FM-ATV Technik (Frequenz Modulation)
auf den Frequenzen um 1.2 GHz, 2.4 GHz und 10 GHz liegen, aber auch AM-Modulation
und 70cm sollen nicht vernachlässigt werden.
