[hpsdr] New Hermes board

[Helmut]

Hi Simon,

I guess you call Hermes 16 Bit Hermes 10 and Hermes 14 Bit Hermes 10E following the Apache names, hi. No, all joking aside, I tested both boards intensively using the current protocol 2 firmware and last version of Thetis: the ‘small’ 14 bit board works rather stable of course also together with PS2.0. Occasionally some data packets get lost, indicated by the red flashing ‘seq=’, but no big deal as PS seems to correct all in the following calibration cycle.
Another story with the 16 Bit version: While all major functions work ok, it’s a big luck to get PS started. Since other testers reported on a temperature sensitivity of the board (FPGA ?) I cooled down the board to 5°C and found no difference.

Helmut,

I know a couple of people using Protocol II with Hermes 10 and 10E who have not reported any problems. Having said that the software they use isn't taxing the Hermes too hard. At present I use the 8000, my 10E sits on the test bench.

Don’t forget that we even have no stable protocol 2 firmware version for the original 16 Bit Hermes design yet. The handmade UDP in the FPGA seems to be the Achilles heel.
