FunCube PRO+ vs RTL-SDR

aunumero73 Over on YouTube has posted a video illustrating the difference in FM Selectivity on the FunCube Dongle Pro+ and a R820T tuner based RTL-SDR. The FunCube Dongle has an expected performance advantage over the RTL-SDR but one must consider the price difference ($190 vs ~$20) between these two devices.

Gqrx receiving broadcast FM using RTL-SDR and Funcube Dongle

Gqrx receiving broadcast FM using RTL-SDR and Funcube DongleA short demo video showing reception of wide band broadcast FM using Gqrx SDR and comparing the Funcube Dongle (96 ksps) with an RTL2832U-based DVB-T dongle (running at 900+ ksps). The video also demonstrates switching between two input sources at run time. Gqrx is an open source software defined radio receiver powered by GNU Radio and Qt, read more at: Source

Noxon DAB Stick SDR (osmocom rtl-sdr) RTL2832U

Noxon DAB Stick SDR (osmocom rtl-sdr) RTL2832UFirst attempts on trying the Noxon DAB Stick at 144.800 MHz APRS with the delivered Antenna (indoors). See more here: sdr.osmocom.org This Stick was designed for listening to DAB only. Under Ubuntu it works for DVB-T and as a SDR with a Bandwidth up to 3.2 MHz. Tuning range could be from 64-1700 MHz (not tested with this NOXON Stick) 73 Oliver DL6KBG Source

World’s cheapest INMARSAT reception systen using DVB-T USB dongle (RTL SDR)

World's cheapest INMARSAT reception systen using DVB-T USB dongle (RTL SDR)DVB-T dongles based on the Realtek RTL2832U can be used as a cheap SDR, since the chip allows transferring the raw I/Q samples with up to 3MHz bandwith to the host. I am testing here a DVB-T USB dongle based on Elonics E4000 tuner chip covering around 60-1700MHz (same tuner chip as used in the famous Funcube dongle SDR). For this quick test I am using only a temporary 45cm dish (old unused TV “Camping equipment” dish) and a wideband PCB based Log-Periodic Antenna as a dish-feed. I am loosing some signal due to the linear polarization (-3dB) of the feed whilst the sat is transmitting circular polarization and some losses due to a couple of adapters between Antenna and DVB-T stick. SNR on FFT is around 15-16dB for Inmarsat with this tiny antenna….which I find quite impressive. You really g Source

Dongle Shootout: Funcube vs RTL SDR – Part 1

“A small “side by side” comparison of a Funcube dongle and a cheap RTL SDR DVB-T dongle (Hama Nano) connected to the same antenna and using identical test systems from a geostationary INMARSAT satellite to compare received signal to noise ratios (SNR).

The FCD is used “live” in this video while the DVB-T IQ stream (1MHz bandwith) was prerecorded a few minutes before the video in order to avoid having to switch the dongles and reconfigure software back and forth and thus save some time in the video…” –Ottiki
