Hermes Lite 2 Plus

 The AK4951 COMPANION BOARD for Hermes Lite 2 -- 

Version 4.x

The Hermes-Lite is a low-cost direct down/up conversion software-defined amateur radio HF transceiver based on a broadband modem chip and the Hermes SDR project. It is an entirely open source and open hardware, including the tools used for design and fabrication files.

The Hermes Lite 2 is an innovative QRP HF SDR Transceiver (which you order at makerfabs.com), but it is lacking a few features which make both CW and Voice modes complete. For CW, there is no keyer, no local sidetone, and significant latency.  For SSB, AM and FM, there is no local microphone jack.

The Companion Board is easily installed and adds several features that enhance operation of the Hermes Lite 2:

• Adds a headphone "PHONES" jack to the front panel, with sidetone in CW mode 
• Adds a microphone "MIC" jack with PTT to the front panel
• Adds an IAMBIC keyer to the "KEY" jack, a straight or external keyer usage is preserved, and there is even an electronic bug mode 
• Adds a dedicated Hardrock-50 Power Amplifier control interface with band switching and PTT which follows the transceiver
• Adds a dedicated ICOM AH4 antenna tuner control interface (with a user-built interface cable)
• Adds a local speaker output, with sidetone in CW mode 
• Greatly reduces latency in both CW and SSB modes
