NT1K – RTLSDR W- RTL2832U and E4000 Tuner

NT1K - RTLSDR W- RTL2832U and E4000 TunerTesting out the EzCap EzTV668 that has the RTL2832 and the E4000 Tuner Chip. I think it’s much better that the FC0013 Tuner. However don’t take my word for it. For $20 you can’t complain either way at 00:40 you will hear a conversation on a local repeater (W1TOM 146.940), One of the stations is close by my QTH and with the 2Mhz sampling, you can see both the output of the repeater and the -600khz input from the operator.

GEDOMIS testbed (part 1)

GEDOMIS testbed (part 1)GEDOMIS® (GEneric hardware DemOnstrator for MIMO Systems) is a multi-antenna wireless communication testbed that enables the prototyping and evaluation of physical layer algorithms featuring MIMO techniques. This is feasible thanks to its heterogeneous and reconfigurable structure comprising mixed FPGA and DSP baseband signal processing components, which can be used for the implementation and real-time validation of broadband wireless communication systems. GEDOMIS® is currently hosting an IEEE 802.16e-2005 system (mobile WiMAX) featuring a 2×2 MIMO configuration with a high channel bandwidth of 20 MHz. The physical layer algorithms of the receiver were modeled in Matlab, designed in VHDL and implemented in a real-time FPGA platform from Lyrtech Inc. For more information visit our webpag Source

RTLSDR as a APCO Project 25 receiver

The MachineGeek overt at DangerousPrototypes has posted yet another great update on a RTL-SDR project.

Balint Seeber has done it again! In this video he shows how to take the RTL-SDR dongle and use it in conjunction with the open source OP25 project to successfully demodulate APCO Project 25 (P25) digital radio voice communications. P25 is a term used to refer to a modulation system used by many public safety agencies for digital radio transmission purposes.
