Voltage Isolator - very important! You need to use it in order to prevent the fuse tripping if you wish to connect your dongle directly to your antenna.

The power comes from the antenna socket of the dongle. Simply connect the upconverter or the booster to it and voila.

Precise and stable frequency reading due to the TCXOs used both in the dongle and the upconverter

R820T2 explained.

There is no R820T2 chip and what we buy is the old R820T tuner with just a number added to the name at the end. A few years ago the market of the R820T dongles was beginning to show signs of slowing down so the engineers in China came up with the idea of changing a few passive elements on the R820T PCB in order to improve its performance with the little antenna they supplied. That on its own would not increase sales though, therefore they resorted to a little trick and they added the number 2 to the name. In order to test this theory we swapped the R820T tuner with the T2 on their boards and we did not notice any difference in performance as measured before the swap. The R820T board with the T2 chip performed exactly as it did with the T tuner and vice versa. We concluded that the T2 tuner chip does not exist and the name was only introduced to improve sales.

CONTAGIOUS CANCER DISCOVERED

"Scientists have discovered the first contagious type of cancer that seems to jump between animal species, and they suggest that cancers that spread like viruses could be more widespread than we thought.

Eight different types of contagious cancer have now been identified. We've known about one type in dogs and two types in Tasmanian devils for several years now, but a new study has identified five more types of contagious cancer in four species of molluscs and their close relatives." - www.sciencealert.com
