Got my new rtl-sdr today! Setup with SDRsharp and used supplied long antennae.
Lots of noise - checked without antenna, direct Q. Quad. etc. Found without antenna that a huge noise on 28,813,510 Mhz. Images going all the up - not down only at '0 hz'
Was also present with antenna connected, but less.
Any ideas to get rid of images etc...
Also a central spike not going down (away) using 'correct IQ' tick mark.
