Hi Alexander.<div><br></div><div>Actually I also cantšimagine how to work with UmTRX without heatsink.</div><div>As for extruded enclosure we discussed with you <a href="http://lib.chipdip.ru/273/DOC000273341.pdf">this</a> heatsink (made in Russia).</div>
<div>In Hamburg I also discussed IP65 housing with Jean-Samuel.</div><div>So, something like two parts of square pipe and all outside surfaces should be heatsink.</div><div>š<br clear="all"><div>Best regards,<div>Andrey Sviyazov.</div>

<div dir="ltr">Hi Andrey,<br><br>Thank you for bringing up this issue.<div><br></div><div>1. We definitely need a heatšdissipatingšenclosure even for lab users. My UmTRX in two channel mode heats its heatsink to 50-60C (heatsink is a blue one, which we used at 29c3). Can&#39;t image how it would work without a heatsink.<br>


<div class="gmail_extra"><br></div><div class="gmail_extra">2. Please explain how do we plan to use extruded aluminium. To make sure everyone are on the same page. Better with a drawing.<br><br><div class="gmail_quote"><div>
