[QUOTE="Terryl, post: 1048843, member: 369937"] OK guy's here is an improvement for the dongle, I found that these little SDR dongle's get quite warm when in use for a long period of time, this seems to degrade their performance. (thermal noise) So I found an old CPU heat-sink and used a zip tie and some heat sink paste, zip tied the dongle to the heat-sink and the thing seems to work better, some of the noise floor dropped a bit. Here is the new MK-10 antenna, the improved version will follow. [ATTACH=full]116796[/ATTACH] And here is the dongle on the heat sink. [ATTACH=full]116797[/ATTACH] A USB extension cable is used to get it away from the PC, the PC also contributes to the over all noise received by the dongle. [/QUOTE]
