SDR Hermes-Lite 2

The Hermes-Lite 2 is a Software Defined Radio (SDR) transceiver designed specifically for amateur radio. It is a low cost, compact and completely open platform based on the High Performance Software Defined Radio (HPSDR) concept. The Hermes-Lite 2 is particularly popular with radio amateurs interested in modern SDR technologies and DIY projects.
Here are some of the key features of the Hermes-Lite 2:

 

1. SDR Technology

  • The Hermes-Lite 2 is a pure SDR device, which means that the signal processing is mainly done by software. This provides a high degree of flexibility and allows continuous improvement and adaptation through software updates.

 

2. operating frequencies

  • The Hermes-Lite 2 covers all HF bands from 160 metres to 10 metres, making it ideal for amateur radio use.

 

3. output power

  • The transceiver has an output power of approximately 5 watts, which is suitable for QRP (low power) operation. Many users add a power amplifier to increase the output power.

 

4. Connections and Interfaces

  • The Hermes-Lite 2 is equipped with an Ethernet interface for direct connection to the network. This means that it can be easily controlled from a computer or Raspberry Pi without the need for special SDR hardware.

 

5. open hardware and software

  • The design of the Hermes-Lite 2 is completely open and both hardware and software details are publicly available. This encourages community development and allows for customisation.

 

6. Compatibility with SDR software

  • The Hermes-Lite 2 is compatible with a variety of SDR software such as OpenHPSDR, Quisk, GNU Radio, Thetis and others. This software provides a user interface and allows the transceiver to be controlled and used in various modes such as SSB, CW, AM, FM and digital modes.

 

7. DSP functions

  • The transceiver uses Digital Signal Processing (DSP) for noise reduction, filtering and other functions to ensure high quality reception.

 

8. Community and support

  • There is an active community of developers and users who regularly provide updates, answer questions and share experiences. This makes Hermes-Lite 2 an attractive choice for tech-savvy radio amateurs.

 

The Hermes-Lite 2 is a versatile and affordable SDR transceiver which, thanks to its open architecture and community support, provides an interesting platform for radio amateurs who want to get involved with modern SDR technology and DIY projects.
