Need some help
I just got the RTL-SDR Blog V4, and I've got it working, but it's not performing quite as I expected. So, my primary SW radio receiver is a XHDATA D-808, which I use to listen to amateur radio bands using a GA800 loop antenna. I also use a lot of WebSDRs that I use alongside my D-808. I thought I'd have a go at setting up an SDR for my own use, so I bought the RTL-SDR Blog V4.
Setup was smooth, got the thing working with no problems, but I have a few issues with sound quality and so on. So, initially I tested it by trying out the local FM radio broadcasts, and it received them, but they were very crackly/hissy. I tried adjusting the bandwidth from 50,000 to 100,000+ and the hissing cleared.
I then tried to tune in to the airband frequencies for my local airport. I can receive them, but as soon as someone starts speaking to the tower, or vice versa, everything mutes and all I can hear is something that sounds like someone trying to talk underwater with a mouthful of cotton wool, and I cannot make out what's being said.
The final problem is that I cannot receive anything on any of the amateur radio bands.
Can anyone help?
