[hpsdr] ray of hope

Hi,
... it's just a bad and unlikely pretense that no schematics are available. Such kind of complex multi-layer board can't be designed without exact schematics. Most Layout-Software even needs the schematics for permanent crosscheck.
There certainly exist other reasons for the restraint, hi.

Georg,
I saw David's answer about him lacking time to assemble the boards and supply them. He has plans for working on upgrading the FW/SW part of his project. I, personally, am looking forward to it. He is planning to develope a new 1Gbs protocol compatible with the HPSDR new protocol (P2) (which has been stuck uncompleted, as a matter of fact. See the discussion here: https://apache-labs.com/community/viewtopic.php?f=9&t=2484 ) and new SW for operating the board.
I also asked him for schematics when I purchased the board, but he said he doesn't have it. He is that sort of a wizkid that has the schematics in his head and produces directly the layout. As to the partially assembled boards, his Github site (https://github.com/Dfinitski/Odyssey-2_2017_TRX/find/master ) contains all the info needed to complete them. Like Sid here already mentioned.

First of all, thanks to everybody for the information:
Marc:
I sincerely hope that my inquiry did not come along like I was criticizing anybody. I know how community projects work, and that they at times get stuck because one (or several) of the people involved lack time or are for whatever other reason unable or unwilling to proceed. 
That's all ok - I was just curious about Hermes II's current status.

I basically agree with your opinion that we should keep up with current technologies, and that buying off the shelf products sucks. If you look into my shack / lab, you will find a lot of stuff from companies like HP/Agilent and Rohde & Schwarz, and hardly anything from Icom, Yasu & Co. On the other hand, I see limits for home brewing where certain steps are hardly possible ouside an industrial environment with tightly controlled processes. I don't etch PCB's myself anymore. Soldering BGA's IMHO falls into the same category. I would without hesitating buy a board with that kind of components assembled and do the rest myself.

Between Odyssey and Red Pitaya I would choose Odyssey, for exactly the reason you mention.

Isaac:
I asked David if there are any assembled boards available, and the answer was no, just the partly assembled ones he offers in his web shop. 
As to everything being open source, the schematics are missing. Of course, they could be "reverse engineered" from the layouts, but the preferable way would be if David published them.

A superb piece of hardware for a very reasonable price. In my opinion - this is the real Hermes follower in Open HPSDR spirit come alive (without much talk and pomp).  David Fainitski has designed and produced  a state of the art single board SDR transceiver. It is compatible with Angelia. David actually ported Angelia's firmware. The last version of the firmware provides 8 3.5v digital IO lines. I built a small ULN2803 based board to convert them to OC lines to control my Hercules amp and it works great.
> The 1 watt output from Odyssey proved to be too high for Hercules so I had to put a 6 DB attenuator.
> Connectivity wise David provides 2 versions of FW: New protocol (1Gbs) and Old protocol (100Mbs). The FPGA actually allows 2 slots for both versions to reside in it, it can be switched by the buttons of Yaesu mic that goes into a j45 connector on the front panel of the board. I used both Thetis and PowerSDR for operating Odyssey and got excellent results with both. Unfortunately Thetis - even v2.6.0 - is still buggy, so currently I'm using PowerSDR PS MRX v3.4.9.

All questions, problems and help requests are answered by David usually within 24 hours. David's Odyssey -2 forum is where you can find out how to purchase a fully assembled and tested transceiver https://groups.io/g/ody-sdr/topics .

RedPitaya is more than 50% more expensive and is inferior in many respects. Anyway, it's not a ready-to-use SDR transceiver. And both Apache and Pitaya hardware is hermetically closed.

By chance, many Russian hams did an incredible reverse engineering work to allow the use of the RP as a fully functional SDR. That means using illegal ways to reach a non-profit goal. That's not a "fair" and comfortable approach. By chance, Pavel Denim made a port of the HPSDR firmware -this is NOT a stemlab initiative, just have a look on their different apps and you will understand the quality level and skill of their devlpmt abilities.

See whatamean ? Wink wink, nudge nudge, say no more, say no more.
