GNU Radio + RTL2832 DVB-T USB stick = $20 ultra-cheap Software Defined Radio

GNU Radio + RTL2832 DVB-T USB stick = $20 ultra-cheap Software Defined RadioSource code: wiki.spench.net Also for Windows: wiki.spench.net twitter.com HDSDR with Wine on Linux & Mac OS X: wiki.spench.net For discussion, head to new Google Group: groups.google.com This video features the same device used with Winrad/HDSDR/WRplus: Compatible devices should be: ezcap, Hama nano & Terratec NOXON (get the first two as it has a better tuner – the Elonics 4000, same as FUNcube Dongle, broadest frequency range: 64-1700 MHz).

Measurements of E4000 Filter Responses

I wrote a octave wrapper around the rtl-sdr library of osmocon. With a little change, to also export the rtlsdr_i2c_read/write_reg function as well as the rtlsdr_set_i2c_repeater function. I then let the standard library do its normal work and just before measuring, I overwrite the E4K_REG_BIAS, E4K_REG_SYNTH1 and E4K_REG_FILT1 registers to their appropriate settings.

Raw data is available. The image itself is pretty raw. The only modifications are a shift of 3 dB below 350 MHz, to compensate the loss due to for 3-phase mixing. and a moving average of 10 samples, to smoothen the curve a little.” — kirepudsje

RTL-SDR and GPS/GNSS

Over on Michele’s GNSS blog He has supplied some interesting information on her testing with A Newsky TV28T and GPS signals. It yet again reinforces the idea of E4000 being the current “best” tuner controlled by a RTL2832U.

“For once, the group of innovators is European.
“These guys of osmocom are smart and -what’s even better- their work with the open source team. RTL-SDR is, I believe, one of the freshest finds in the Software Defined Radio domain. The Fun Cube Dongle, developed in UK, is already a very clever tool. But finding the super-tuner Elonics E4000 (note, again a UK Company) in 25$ USB DVB-T dongles and being able to grab data in a 3MHz bandwidth between 64MHz and 1.7GHz… that is really cool.” — michelebavaro
