Update 11 July 2012

Hermes is a single board Digital Up and Down Conversion (DUC/DDC) full duplex HF + 6m multi-mode transceiver.

It is basically the Mercury, Pennylane, Metis and Excalibur (less TCXO) boards rolled into one PCB. The board communicates to an associated PC via 100T/1000T Ethernet.

Hermes has the following features and facilities:

  • Continuous, uninterrupted, receive coverage from 10kHz to 55MHz.
  • Supports Real-Time display of entire spectrum from 0-55MHz (with suitable PC software)
  • Supports 7 fully independent receivers (sharing the same antenna - and with suitable PC software)

  • Separate open-collector PTT connection for amplifier control, etc, with sequencer
  • Microphone PTT jumper-selectable from tip or ring connection
  • Bias for electret microphones via jumper
  • Four user-configurable 12 bit analogue inputs (for ALC, SWR etc)
  • Three user-configurable digital inputs (for linear amplifier over temperature, etc)
  • Can operate from a 13.8v DC supply or +12v and +5v supplies
  • Jumper selected in-built low noise and high efficiency switch mode power supply designed by Kjell Karson,LA2NI – less than 600mA (receive - one receiver) from a 13.8V supply

  • Hermes responds to ping and ARP requests and auto senses network connection speed
  • PCB is 160mm x 120mm, 8 layers


Apollo is a combined 15w PA, Low Pass Filter bank and Automatic ATU. The Apollo project is led by Kjell Karlsen LA2NI.


Hermes can be used as a Vector Network Analyzer: VNA

Update 7 August 2011

The primary PCB layout team member of Hermes, Abhi has a blog on Hermes at http://hpsdrhermes.blogspot.com/ . --KV0S, Dave

Update 7 July 2011

A prototype board has been built and tested. The board is fully functional and meets or exceeds the performance of the Mercury/Penelope/Metis/Excalibur boards the design is based on.

Some minor board layout issues are currently being addressed and a pre-production layout is presently being prepared. The KD5TFD and W5WC versions of PowerSDR(TM) as well as KISS Konsole have been modified to provide native Hermes support.
