Hi all.
Before plans I need to discuss conceptual questions about UmTRX new PCB
release:
1) PCB size will be 99.5x149.5mm to use popular 100 mm eurocard housings.
Is it Ok?
2) I can't find RJ-45 gigabit module with industrial temperature range
(-40C..+75C). Either use 0-70C agree or help required.
3) How important to keep OCXO and TCXO together? May be TCXO will be
enough?
4) How important to keep 30 pin debug connector? May be 10 pins will be
enough?
5) Can I place some IC's at bottom of PCB? DC/DC for example, are there
objections?
Best regards,
Andrey Sviyazov.

Andrey Sviyazov, I think this question is mostly for
you.
Could you please outline the development plan for the UmTRX hardware
(with all associated things, like RF board design)? What are critical
dependencies? E.g. when we should decide on the casing?
My feeling is that we've lost the track and focus on things which are
important, but not at this stage.
