Empfangstest im 2m-Amateurfunk Band 144-146MHz – Source
A 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
First 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
Testing 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
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!
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).
Image of dongle received on 4/23/2012:
“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
