Digital ATV Transmitter article

An article on a Digital ATV transmitter by Charles Brain, G4GUO, has just been published on the web.

Charles uses the Universal Software Radio Peripheral (USRP2) card developed by Matt Ettus, N2MJI.

The system comprises a Hauppague PVR-150 hardware MPEG 2 encoder PCI card, a 4 core Pentium 4 P.C running Fedora Linux 12, the USRP2 and RF bricks for 70cms and 23cms.

For reception a standard Fortec Star satellite set top box (STB) is used for DVB-S and for DVB-T reception a regular U.K digital TV with a homebrew receive converter are used.

The 6-page article starts on page 2 of the Autumn edition of the free TAPR PSR magazine which can be downloaded at
