Declarations of Conformity
The OpenHPSDR Hermes Transceiver complies with FCC Part 97 rules for the Amateur Radio Service.

Specifications & Highlights:

  • Continuous, uninterrupted, receive coverage from 10KHz to 55MHz.
  • Supports Real-Time display of entire sectrum from 0-55mHz (with suitable PC software)
  • Supports 2 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
  • 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
  • Software-selectable 31dB input attenuator in 1dB steps
  • High performance receiver – same specifications as the HPSDR Mercury receiver (ie Dynamic Range typically 125dB)
  • FPGA code can be updated via the Industry Standard TCP/IP network Ethernet connection
  • Seven user-configurable open-collector outputs, independently selectable per band and Tx/Rx (for relay control, etc - with sequencing via PC code)
  • 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
  • I2C bus connector for control of external equipment
  • Full QSK operation (performance dependant on associated PC and control software)
  • Low-level transmitter output for transverter use via user-selectable output attenuator
  • Stereo audio outputs at line and headphone levels
  • In-built 1W stereo audio amplifier for directly driving speakers
  • Direct, de-bounced connections for a Morse key (straight or iambic) and PTT
  • Low phase noise (-137dBc/Hz @ 1kHz) 122.88MHz master clock, which can be phase-locked to an internal 10MHz TCXO or external fequency reference
  • Low phase noise (-140dBc/Hz @ 1kHz at 14MHz) 122.88MHz master clock, which can be phase-locked to an internal 10MHz TCXO or external frequency reference
  • Direct ribbon cable interface to Apollo 15W power amplifier, low pass filters and automatic ATU
  • Industry Standard TCP/IP network Ethernet interface supports static, APIPA or DHCP IP address
  • Hermes responds to ping and ARP requests and auto senses network connection speed
  • Eight (8) Layer PCB design for the most professional, state-of-the-art, design available.
