Microtelecom joins an impressive list of manufacturers from around the world whose products are exclusively sold in North America through DX Engineering, including DX Commander, microHAM, OptiBeam HF Directional Yagis, RM Italy Amplifiers, and WiMo.

DX Engineering—celebrating 25 years of service to the amateur radio community in 2025—is committed to forging exclusive arrangements that help hams in North America receive high-performance amateur radio products faster, save on shipping costs, and enjoy prompt customer service and technical support from a team of operators with a combined 1,000-plus years of on-air experience.

Microtelecom: A History of Innovation

Microtelecom develops and manufactures radio and telecommunication devices for special applications, multichannel acquisition systems, and other advanced electronics. Since 1998, the Udine, Italy-based company has specialized in a range of disciplines, from analog and RF circuit design to FPGA-based digital signal platforms.

In 2017, Microtelecom began a technological partnership with ELAD for the development of telecommunications software. They joined the ELAD group in 2021 (ELAD SDR transceivers and receivers are also available at DX Engineering.)

Microtelecom unveiled its Perseus22 receiver at the Friedrichshafen Ham Radio Exhibition in 2022.

Ham Radio Question of the Day: What does FPGA mean?

FPGA stands for Field Programmable Gate Array—a configurable integrated circuit that can be repeatedly programmed, unlike other chips that are built to perform a single job. An FPGA consists of programmable logic blocks that can be connected to meet the programmer’s needs, often for digital signal processing (DSP) in the amateur radio realm.

The term “field programmable” means it can be configured outside of the factory to perform a number of tasks, including serving as the core for building an SDR transceiver—a capability available in RedPitaya SDRlab and STEMlab kits available at DX Engineering.

With the RF direct sampling employed in Icom IC-7300, IC-7610, and IC-R8600 transceivers, RF signals are digitized by an analog-to-digital converter and immediately processed by the rig’s FPGA, greatly reducing distortion that naturally occurs in various mixing stages found in superheterodyne receivers. This technology is also used in Icom D-STAR third-generation repeaters.

Perseus22 4-Channel Direct Sampling Receiver: Loaded with Ham-Friendly Features

This advanced receiver offers many features and benefits for amateur radio enthusiasts, including dual continuous frequency coverage from 10 kHz to 225 MHz, typical image rejection greater than 70 dB, and excellent dynamic range on four independent receivers (two VLF-HF and two VHF). The 8.4″ W x 1.7″ H x 8.6″ D device weighs in at 3.7 lbs.

Each receiver has a dedicated SMA female antenna input, and all four channels are synchronously sampled by a high signal-to-noise ratio, 14-bit A/D converter and processed by a software-defined digital down converter and FPGA implementation.

The four dedicated output channels are routed to the host PC via the USB 3.0 controller, achieving synchronized true diversity reception and wide bandwidth IF applications. Supported modes are AM, LSB, USB, CW, CWrev, RTTY, RTTYrev, FM, WFM (RDS in development), SAM, QSAM, DAB+, and IQ. Presently available sample rates are 250, 500, 1,000 and 2,000 kSps, with the maximum span currently displayed at 1,600 kHz.

All channels include an analog RF front end equipped with attenuators, preselection filters, and amplifiers. The receiver enclosure is machined from solid aluminum and finished with a non-reflective black surface treatment.

Perseus22 SDR multichannel software was created by a team formed by ELAD and Microtelecom developers with years of experience developing software for DSP. It takes advantage of an agile GUI interface platform, integrating past DSP design experience to accommodate future modules for demodulators and decoders.

The software features a simple, intuitive, and efficient graphical user interface.

The Perseus22 comes with:

  • AC-to-DC switch mode power supply with AC power cord: 9Vdc 4.45A output, 80-264 VAC input
  • 78.74-inch USB 3.0 A-to-B cable
  • 4 SMA-BNC adapters

System Requirements

Perseus22 software is a 64-bit program that uses OpenGL libraries. It supports Windows 10 and 11 operating systems. Future releases and third-party software will be available soon for IOS, Linux, and others. A computer with a USB three-port (Type-A or Type-C connector) is required to operate the Perseus22.
