[hpsdr] Current Hardware Platform ?

[Laurence Barker]

For anyone interested in what I plan to have a go at, you can see a
description of the signal conditioning I plan for the Red Pitaya at:

-part-3-signal-conditioning

Hermes-Lite 2.x sounds like an interesting project too. There's probably
little discernible difference between a 12 bit, 14 bit and a 16 bit ADC -
all are capable of performance well into the upper end of analogue
receivers.

Hi Laurence,

Seems the Red Pitaya hype is still going on, hi. Of course, Pavel did a fine
job emulating the Hermes firmware, but there remain a lot of severe deficits
of the hardware or better the architecture (frontend-match/preamp,
Nquist-filtering, lack of audiocodec/ high latency, signal purity and SFDR
of DAC output etc.). If you provide all the possible, but necessary
improvements, modifications and extensions you will certainly hit the $500
wall.

Steve's, KF7O, terrific HERMES-Lite 2.x performs much better and needs only
a $100 budget. BTW I can't discover significant distinctions between Altera
and Xilinx. Both offer similar product lines.

But finally good news for all RP enthusiasts:  Obviously the RP works now
soundly with Pure Signal 2.0 implemented in the latest release PowerSDR mRX
PS v.3.3.14.
