Hello Simon and all,

If you put your SDR in an unpainted aluminium box it would run much warmer than if you would paint it with something that is black at infrared frequencies.

Easiest something based on carbon dust which is black at all frequencies.

The properties of different colours (in the visible range) may be unexpected in the infrared.

The temperature of an aluminium box might easily be twice as high as the temperature of the same box when painted black.
