Hermes - A DUC/DDC Transceiver
Project Leader: Kevin M0KHZ
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)
- Each receiver can display 48/96/192kHz of spectrum
- Blocking Dynamic Range (ARRL Method) - no detectable gain compression below ADC overload
- High performance receiver – same specifications as the HPSDR Mercury receiver (ie Dynamic Range typically 125dB)
- Transmit and receiver image rejection > 110dB
- Full duplex operation, any split over entire 160m to 6m range.
- Transmitter two-tone 3rd order IMD of -50dBc on 20m @ 400mW output
- 500mW RF output on 160 – 10m amateur bands, 350mW on 6m
- Built-in high performance preamp, with a noise floor typically -135dBm in 500Hz

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

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.
Ken, N9VV, has a lot of information regarding Hermes on his web site here http://www.n9vv.com/hamradio.html
There are also the Hermes Board Build Notes
