Hello, The TVRX2 sounds very interesting. How are the two receivers mapped to the output? Does each receiver map to a different frequency range on the output?
The two receivers would be great for decoding and following trunked radio systems with a dedicated control channel. 73 Eric ----- Start Original Message ----- Sent: Mon, 14 Feb 2011 14:38:36 -0800 From: Matt Ettus <m...@ettus.com> To: gnuradio <Discuss-gnuradio@gnu.org> Subject: [Discuss-gnuradio] 3 New Products from Ettus Research > > ====================================================================== > > We are pleased to announce three new products for use with the > USRP family of Software Defined Radios. > > > 1) GPSDO Kit > 2) TVRX2 Daughterboard > 3) SBX Daughterboard > > > ====================================================================== > > 1) GPSDO Kit > > The GPSDO is a GPS-disciplined oscillator, which uses a GPS receiver > to steer the frequency of the master oscillator with very high > accuracy.
