[QUOTE="aceb, post: 902437, member: 268811"] No, you won't be able to listen in to the old bill or any other airwave user, either with an SDR or hardware. True the RTL dongles do suffer with their low dynamic range but much of the noise is generated from the USB port and PC in general. I've mounted mine is a copper clad container and used decent connectors and cable through out, the PC is already as quiet as I can get it for radio work and the end results are excellent. The dongle definitely does not lack sensitivity in the urban environment, waterfall traces and recovered audio easily match my Icom 8500. To get the best out of these dongles a big antenna and appropriate filtering are recommended. [/QUOTE]
