Recent Update on Software Plugins for Fobos SDR

We’re excited to share more about two recent software plugins that enhance Fobos SDR by bringing native SDR++ support, making it the second fully integrated software option alongside uSDR. These plugins offer unique capabilities and expanded functionality, improving the SDR experience for Fobos SDR users.

Plugin Highlights:

Plugin 1 (by Alexander Rouma)

• Original Repository: GitHub – AlexandreRouma/SDRPlusPlus

Advantages:

• Enhanced HF input capabilities, allowing HF-band wave reception without bandwidth restrictions
• Eliminates spectrum mirroring on the HF band
• Supports bandwidth as low as 1.2 MHz through software downsampling

Limitations:

• High computational demand
• Lacks GPO control
• No device information display

Plugin 2 (by RigExpert’s team)

• Original Repository: GitHub – RigExpert/SDRPlusPlus

Advantages:

• Native streaming with no intermediate software processing, reducing computational load
• Supports GPO control
• Displays device information, including software, hardware, firmware, and API details

Limitations:

• HF direct sampling is available only up to a 50 MHz sample rate
• Mirrored spectrum on HF band
• Minimum RF sample rate is 8 MHz

Performance Note:

For optimal performance, particularly on the 50 MHz band, we recommend using a PC with an Intel Core i5 3.4 GHz or higher processor.

These plugins significantly expand Fobos SDR’s functionality and compatibility with SDR++. We’re eager to hear your feedback and learn how they work within your setup!
