I'm beginner user of SDR, I have (NooElec NESDR SMArt Bundle)
I'm using as software SDRSharp,
I can listen to VHF without any problem, but when I want to listen to HF I can not catch any signal.
I'm using below setting
Which one is it?
http://www.nooelec.com/store/nesdr-smart.html
The top one covers 24MHz upwards, "Additional Information - Frequency Range (approximate) 25MHz - 1750MHz"
The bottom one uses a converter, not direct sampling.
(Direct sampling can give very poor results.)
