ARLA/CLUSTER: Radioamadores alemães detectam transmissões não autorizadas no segmento de amador de 144 MHz

[João Costa > CT1FBF]

Unauthorized transmissions in 144 MHz satellite allocation

The *DARC* reports unauthorized transmissions are taking place in the 144
MHz satellite segment of the 2m amateur radio primary allocation.

A translation of the DARC post reads:








*In the 144.010 MHz to 144.020 MHz range, illegally operated transmitters
are increasingly being operated as "water vitalizers" or "water
energizers". The manufacturer specifies 144.015 MHz as the transmission
frequency in its product description.The DARC EMC department asks for
further information with location information about conspicuous signals in
this frequency range, in preparation for collective complaints.The devices
apparently generate fields with considerable field strength and a long
range. The signals appear increasingly in the morning or in the evening.
The illegal transmitters are typically in operation for 5 to 60 minutes
(integer multiples of 5 minutes). The signal is generally very stable in
frequency, but occasionally shows short-term fluctuations of up to a few
100 Hz. Otherwise the carrier is not further modulated.The frequency range
144.000 MHz to 146.000 MHz is assigned to the amateur radio service in
Germany as the primary exclusive user.*
A video of the interference caused by these devices and a map showing some
of the cases so far detected in Germany can be seen at
