I have a SDRPLAY 1 with sdruno but i do not get any stations even music stations on HF, i see some signals but most are rumble sounds...
is there a frequentie that i can tune in to that is so strong that i must here something ?, the SDRPLAY is connected right with the SDRPLAY.
this is on 20 meters,

but also on broadcast frequenties i recieve nothing, mijn question is then
- is there something i have to set in de SDRUNO application ?
- is it posible that the play is broken?, if so can i check that somewhere ?
setup,
- SDRPLAY 1
- SDRUNO application on Windows10
- antenne is a magnatic loop 20 meters (indoors)
Tnx for your time
Andre
