The v4 USRP has a fan header next to the power jack. I don't know what the recommended solution for v3 USRPs is, although I suspect it's along the lines you mentioned. :-) Some v3 USRPs already have a power lead takeoff for an oscillator sub-board on the bottom of the USRP; I suspect the fan leads could attach to the same place. Hopefully there is filtering enough that the fan motor would not butcher the oscillator signal, but someone else will have to speak to that.

The only unanswered part is where do you hook the fan up to? Does the USRP 4 have the holes for a connector or is it cut the fan connector off and wire direct to the board? 73 Eric _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
