The Microtelecom FM+ converter is a powerful tool for the ambitious FM band DXer. This converter covers the FM broadcast band from 87.5 to 108 MHz. The converter was designed especially for the Perseus. 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 (supplied on a mini CD) 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. Required BNC jumpers and power supply not included.

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)
