[hpsdr] Hermes status?

[Barry Buelow]

Kevin,

Thanks very much for the update.  Glad to hear of all the progress and my 
sincere thanks to all contributors.  


I guess the answer to my question is somewhere between Easter Bunny and Dayton!

Hi Barry

I’ll ‘probably’ regret making this statement :)

Development progress on Hermes is alive and thriving, the gamma schematics have 
been signed off, with the exception of two late changes, namely a probable 
change to the mic connector to an RJ45 and the addition of a buffer amp and 
external header for the 122.88 Mhz clock (possible future use with 
transverters).

The alpha board proved the Hermes concept and we have been battling to rectify 
spur issues to ensure the receiver performance is as good Mercury. This has all 
been down to PCB layout and the number of clocks. Tony has made SIGNIFICANT 
progress this summer to resolve these issues and we are now moving confidently 
towards a gamma board.

It is anticipated that the gamma layout will be the final design, so if we draw 
out a reasonable time line, I would guess at:

PCB’s returned from manufacture mid November.
PCB’s distributed to developers for component population late November.
10 gamma prototypes tested (auto test harness thanks to Phil) pre Christmas.
Minor mods to layout (based on Metis)
10 off pre-production board produced by CM mid to late February 2011.
Confirmation that production OK late April.
TAPR to push the mass production ‘button’ after Alex orders have been filled.

All of the above based on the assumption that the Hermes gamma board is OK and 
we don’t need another spin of the board. Plus this is only my guess, once again 
based on the development of Metis, perhaps Scotty can confirm?

Hope this helps your decision tree?
