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

UHF MIL SATCOM with 6el Yagi and cheap RTL SDR RX

UHF MIL SATCOM with 6el Yagi and cheap RTL SDR RXTesting a homebrew 6el Yagi with no preamp directly connected via 2m coax cable to a DVB-T dongle used as cheap SDR. Nice signal strengths from UHF military satellites. These data streams are around 244 MHz. There are various downlink signals in the 240-270 MHz range. These are only used as test signals since they are highly encrypted and cannot be decoded, of course… For more information and a frequency lists please see PJ Marsh’s website: Source


Verified RTL2832u & E4000 Source

Just thought I would give some links to a source based on personal experience. I’ve ordered multiple dongles from AliExpress with GREAT results. I paid extra for DHL shipping and my dongles arrived from China to the West Coast of Canada in just 3 days!

Here are links for: 1 Dongle, 2 Dongles, 6 Dongles from Newsky being sold as model TV28T (Note: slight circuit difference from original TV28T received, but works)

Note to NEW AliExpress members, I believe you should get an additional $5 at checkout. I noticed when placing my first purchase there was a coupon available just before payment. Not sure if there was a minimum order (I spent $65 the first time for 2 dongles + DHL shipping).

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
