[soft_radio] spurious signals on the HF spectrum on reception

[Helmuth Jim Meyer]

Hi group, has anybody made bad experiences with any spurious singals, 
spikes etc. during reception of broadcast or amateur radio stations on HF 
with SDR???
Only the computer normally produces a lot of disturbing signals from its 
main osciallator and all the divider stages for all the various applications..
Any reports please ???
Jim...
