After the great response to the predecessor models
SUP1 and SUP2, we present the successor, SUP3, which
has numerous new features. First of all, there is now
The SUP3 generates a high-quality FM signal including an individually configurable RDS signal. In additi-
on to the analogue audio feed, a USB interface also allows digital audio data to be fed in. The operation is
clearly arranged via a practical combination of rotary encoder and OLED display; in addition, PC software
allows easy control of the SUP3 from a PC.

a digital signal feed via USB. This allows you to use
a PC or other device with USB sound output directly
as a signal source. And since the VHF test generator
can also be operated with batteries and an RDS signal
to be output can be stored in its EEPROM, you can,
for example, use the mobile combination of test ge-
nerator and smartphone to put the coveted radio tre-
asure through its paces before buying it, even if, for
example, VHF reception is not possible in a particu-
lar space. Such a generator is also excellently suited
for demonstrating radios, whether in the showroom
or in a museum, as it makes the radio independent of
antenna reception and also offers the possibility of
outputting your own content, such as explanations in
an exhibition.
However, the main purpose of use is probably the
repair and restoration of VHF radio receivers. An ex-
act calibration is only possible with a test signal that
conforms to standards. The use as a VHF transmitter,
however, even if it is only for short distances, is pro-
hibited!
