Ok Martin , well  you  never know, when you  might need= a  stable carrier  :)

Keep looking,  take a  loo= k at the  compatibility  list  for  Simon Browns  SDR software , that is a  good range of  options ,  $$ dont = ; translate directly to   performance , its only a  A/D chip&n= bsp; with a  few others tagged on the  back  , the  rtl sdr = dongle is  =C2=A35 , running  directly on 7  with = 40  ft ae  and atu   https://www.youtube.= com/watch?v=3D7Le-1aW9BR4
