[hpsdr] Hermes Wiki updated

[W4sc]

'',,,,,,, and while investigating the verilog code for both, I had the 
insane idea of merging the verilog code of Mercury and Penelope into a 
single fpga! ........''

Not an insane idea at all,, The natural, and desired, developement path,,,

When will assembled/tested Hermes be available?  Measure performance??

***** High Performance Software Defined Radio Discussion List *****

Phil VK6APH has updated the Hermes Wiki webpage
http://openhpsdr.org/wiki/index.php?title=HERMES
to include a brand new picture and loads of great
information. Here are some of the tantalizing new
features:
--------------------------
[] Uninterrupted coverage from 50kHz to 54MHz
[] Transmit and receiver image rejection > 110dB
[] Full duplex operation, any split over entire 160m to 6m range
[] Eight independent receivers using the same antenna
[] 500mW RF output on 160 – 6m amateur bands
[] Built-in high performance preamp, with a noise floor typically
-135dBm in 500Hz
[] Software-selectable 20dB input attenuator
[] High performance receiver – same specifications as the HPSDR
Mercury receiver (ie Blocking Dynamic Range typically of about 125dB)
[] Built-in Altera USB Blaster(TM) for updating of FPGA code via USB
[] Seven user-configurable open-collector outputs,independently
selectable per band and Tx/Rx (for relay control, etc - with
sequencing via KISS Konsole)
[] 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)
[] Optional in-built switch mode power supply – less than 500mA
(receive) from a 13.8V supply
[] I2C bus connector for control of external equipment
[] Full QSK using the Kiss Konsole software, since digital signal
processing is not used in the controlling PC for CW carrier
generation
[] Provides up to eight simultaneous receivers from one antenna if
suitable PC software is used
[] Diode-protected USB interface
[] Low-level transmitter output for transverter use (0dBm) as well
as 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
[] 122.88MHz master clock, which can be phase-locked to an
internal 10MHz TCXO or external frequency reference
[] Jumper-selectable external frequency reference, with signal
processing, to suit numerous GPS-locked 10MHz reference sources
[] Direct ribbon cable interface to Apollo 15W power amplifier,
low pass filters and automatic ATU.
