    DVB-T Dongle Heatsink Mod

    Hi all,

    Have recently mounted my ADSB antenna on the roof from being inside for many months and am now enjoying much greater range. The DVB-T Dongle is now in the roof cavity and in summer the temperatures there get really hot. Has anyone cracked open the dongle for a heatsink mod? Was also thinking of placing a small solar panel on the roof to run a fan on the heatsink as well. Any info or suggestions?

    Cheer, Chris.

    The latest RTL-SDR Blog dongle uses an aluminum case with some 'heat tape' to couple the hot bits to the case. You could do that but using a small aluminum Northbridge heatsink.

    As for fan,, there is 5v available on the RPi pins to run a small fan.

    Some nice ideas on that site. Found some thermal images there as well. Already have a small aluminium enclosure - will sift through the computer parts junk pile for bits and pieces, and a good excuse to get the Dremel out! Also didn't realise all the different dongle configurations that exist out there, a lot of talk of "TCXO" .. will need to do a bit more research ....
