RCD CR-3000C →
Field-strength indicator with frequency counter

- wanted item
BMR-1000 was a mobile frequency counter with built-in field-strength
indicator and acoustic feedback,
jointly developed in the mid-1980s
by the Dutch Radio Monitoring Service (RCD) and
external contractor Essa Electronics in IJmuiden (Netherlands).
Manufactured by Essa,
the device was used to determine the frequency of a mobile
radio system in close proximity, in order to be able to intercept it.
The RCD
mainly used it to find clandestine users of the frequency spectrum.
|
The unit has the form factor of a standard car radio, so that it could be
built into virtually any vehicle, without attracting too much attention.
It is powered by the 12V car battery (10-15V DC).
The BMR-1000 has a frequency range from DC to 1 GHz and will automatically
lock onto the strongest signal when in close proximity of a transmitter.
When locked, the 8-digit display will instantly show the
frequency of the intercepted signal.

The name of the device was derived from the initials of the developers:
Ben and Mart – both of the RCD) – and Rob of Essa
Electronics. The number 1000 stands for the maximum frequency, which is
1 GHz. In 1997,
the device was superceeded by the CR-3000C.
