$10 ultra-cheap Software Defined Radio with RTL2832 DVB-T USB stick

(1/2) > >>

before i forget when you start up HDSDR you need to go to the left side wind were you will see buttons saying sound bandwidth and so on there is one that says start one you hit start click on BANDWIDTH and pick on the top right of the pop up panel 192000, and then you will hear what your looking for when you find it, as if you dont do that you will have allot of trouble tuning into stations.

look at the photo below and you will see the panel open and set to 192000

Also i have been told the  USB 2.0 Digital DVB-T SDR+DAB+FM HDTV TV Tuner Receiver Stick RTL2832U+R820T2 R1 Dongle will get warm when being used so dont panic , unless you see the cover melting or its on fire and the likelihood of that happening is rare.

I have been told this is the better conector to use if you just want to use the the USB 2.0 Digital DVB-T SDR+DAB+FM HDTV TV Tuner Receiver Stick RTL2832U+R820T2 R1 without useing the spyverter.

ive also been told by Troy (Mr T) that you should use a usb extension cable, dont plug the USB 2.0 Digital DVB-T SDR+DAB+FM HDTV TV Tuner Receiver Stick RTL2832U+R820T2 R1 into a usb port on its own as it will suffer some interference from the pc/laptop.

more of an update

i have been advised that the Ham it Up HF Converter is ok if you dont live near a hi RF area reason is it suffers from bad front end overload, but thats not the end here, there is a better one to get, that dont suffer from front end overload no near as bad as the others, its called Spyverter.
