Hi all.<div><br></div><div><div>Before plans I need to discuss conceptual questions about UmTRX new PCB release:</div><div>1) PCB size will be 99.5x149.5mm to use popular 100 mm eurocard housings. Is it Ok?</div><div>2) I can&#39;t find RJ-45 gigabit module with industrial temperature range (-40C..+75C). Either use 0-70C agree or help required. </div>
<div>3) How important to keep OCXO and  TCXO together? May be TCXO will be enough?</div><div>4) How important to keep 30 pin debug connector? May be 10 pins will be enough?</div><div>5) Can I place some IC&#39;s at bottom of PCB? DC/DC for example, are there objections?</div>

Andrey Sviyazov, I think this question is mostly for you.<br>
<br>
Could you please outline the development plan for the UmTRX hardware<br>
(with all associated things, like RF board design)? What are critical<br>
dependencies? E.g. when we should decide on the casing?<br>
<br>
My feeling is that we&#39;ve lost the track and focus on things which are<br>
important, but not at this stage.<br>
