Perseus goes FM
The SDR-specific advantages that shortwavelistener enjoy for years already, have now become available to the ambitious FM-DXer also. The converter FMplus is a development especially for the FM broadcast band from 87.5 - 108 MHz.
This converter has now established itself as the ultimate workhorse for FM DXers. It can be operated in conjunction with any shortwave receiver that covers the frequency range of 0-40 MHz and provides appropriate bandwidths for Wide FM.
The full performance unfolds the FM+ through its software, which is based on the Perseus as a terminal:
The converter was designed especially for the Perseus. The software (part of the delivery) includes an outstanding Stereo Demodulator and an extremely sensitive RDS decoder for station identification. This separates the FM+ from all other converters.
An antenna for frequencies below 30 MHz can be connected to the converter. The signal will be passed to the Perseus when the converter is not in use.
The FM+ Software performs wide band stereo FM demodulation with RDS decoding of the tuned signal with overall features which are similar to the Perseus software application. The selectivity filter operates at 500 kS/s with a maximum IF bandwidth of 400 kHz and can be narrowed down to 20 kHz for FM DX operations. Three spectral views are available:
- RF (RF spectrum view, like in the Perseus software,
- MUX (demodulated stereo multiplex)
- RDS (showing the RDS signal spectrum if present).
Shown RDS data are station name, program type and PI code.
The ideal addition to the Perseus! Of course, the well known intuitive bandwidth setting using the mouse as well as broadband recordings of up to 1.6 MHz wide ranges are possible.
