SDR - wonderful

As for the TV reception I am sorry to say that I reinbekomme absolutely no station in Aachen. Even adjusted by using a self-built BiQuad to about 600 Mhz nothing works.
As SDR receiver but the unit is reasonable. Chips built with my delivery are RTL2832U and Tuner: R820T. So top requirements for a low cost SDR. For the driver I Zadig 1.1.1.139 with WinUSB used (select is Bulk-in interface (interface 0)). As SDR receiver I use SDR # 1.0.0.1174. In other version combinations of the drive is not recognized. Web search for "SDR-install" should Zadig and SDR # deliver the correct version.
The reception area is deep enough to receive wonderful most radio stations at 88-108 MHz. Also not too far beneath frequency ranges can be observed with sufficient signal strength various narrowband transmissions. Amateur radio over 2m supplies with me no good results and will probably be possible only very limited, if one does not perform frequency extension by means of additional hardware. 2m and 70cm amateur radio band can be received well in the near surroundings - are unfortunately greatly disturbed me. Could be due to other electrical equipment. Upwardly to, as they say, to more than 1 GHz signals be receivable.
In addition to the supplied antenna, a 2m-BiQuad antenna has been tested, the better the reception characteristics unfortunately only slightly.
