[QUOTE="smoggy07, post: 965391, member: 298987"] I'd be very concerned with RFi from the Dell, when I had my Icom PCR1000 PC controlled receiver I thought about installing it inside the Dell desktop to hide it away where the CD/DVD drive sits, it didn't fit so I never installed it but I was getting 3 to 4 pound of crap (in old CB radio moneys) from the Dell with the lid/bonnet open compared to the 2 to 3 pound of static with it closed (which was the norm for that radio on that PC) It seems that everything from the power supply used to the fans to the HDD and even the processor in those old Dells spew noise all over the HF bands If you can, make use of many many Ferrite rings (if thats how you spell it), wrap a few round the Dell kettle lead, the monitor kettle lead, if you can I'd try and get one on the VGA cable and on the leads out of the power supply on the inside, also on your USB lead from the SDR and the antenna cable too I'd be inclined to advise against installing inside the PC unless you can shield it very very well, maybe by making an improvised Farraday Cage, even then you will have weak points where the USB and antenna lead leave the unit Also where the antenna socket has been installed next to the sat card, it's earthing out to the PC metalwork so I wouldn't be surprised if that caused RFi too I really do like where you're going with this project and wish you well with it, if you get good results I might be tempted to build my own Keep us up to date with your findings mate [/QUOTE]
