Perseus

The Perseus receiver is an SDR with a direct sampling architecture and the ability to store up to 1.6 MHz of the RF spectrum on a PC. The effective dynamics exceeds 100 dB in SSB and CW also for signals of minimum spacing, an excellent value that few devices reach. At the center of the electronics are a 14-bit analog-to-digital converter operating at a speed of 80 Msps and a subsequent high-performance FPGA (Field Programmable Gate Array) digital downconverter. The primary aspect in this receiver is the analogue front-end sized to satisfy even the most demanding operators including 10 dB steps attenuators, a high dynamic preamplifier with an IP3 of +31 dBm, a bank of 10 filters for signal preselection. The following table shows the frequency ranges of the aforementioned automatically selected filters according to the tuned frequency:

As observed, the bandwidth is significantly less than one octave in favor of IP2 (second order intercept) and distinguishing itself from many other receivers that use fewer filters. The operator can also switch-off the preselector by directly connecting the antenna input to the next stages, in this mode Perseus is used as a broadband spectrum analyzer from 10 KHz to 40 MHz with over 100 dB of dynamics and a resolution of 10 kHz . The software, for 32 and 64-bit Windows operating systems, is up to hardware performance with all the traditional commands of an HF receiver plus the specific ones organized in the main interface. The CAT protocol on virtual serial port and the virtual audio channel (VAC) output also allow the addition of third-party software.

Default interface of the Perseus software

The S-meter indicator shows the intensity both in standard S points and in dBm units with a linear function on the entire scale, the accuracy reaching less than 1 dB allows the use of Persus as an RF measuring instrument. Among the external accessories we mention Tmate, a mini console with a solid aluminum knob and 4 programmable function keys. With this through the dedicated software we perform the main tuning operations in the typical modes of a conventional radio.

Perseus performance and practical notes :

The Perseus receiver is, under different points of view, an original project conceived having very clear the real needs of the fans. Factors such as the almost constant sensitivity over the entire frequency range, an excellent dynamic even for near signals, the recording of an entire band segment, are aspects that are not recognized in products of brands rooted in the sector for much longer. An advantage in terms of performance combined with flexibility in the mode of use is virtually limited by the operator's imagination alone. For example, AM-DX enthusiasts can memorize substantially the entire range of medium waves during an external monitoring session, where the reduced noise allows unparalleled receptions, then reproduce all the signals at a later time, choosing to listen to any output in any mode combination (SSB, AM, synchronous AM), bandwidth, etc.
