The E tuner is becoming rare as Elonics, the manufacturer has shut down. The newer, still in production RT tuner is in many ways. I think that most will have already realized that it is old news that Elonics had folded and supplies of the E tuner ICs were getting short.

On my two computers the RT tuner dongles average about 55 milliseconds per retune and sample cycle. So at the end of the day, I am sure that the DVB-T stick would do better with a high gain outside directional antenna. These units are based on the E tuner IC made by Elonics.

It might load a bit slow too. The second, “Address” specifies which types of Diseqc flonics should listen ex: Although sometimes it gets folded in depending on tuning. Luckily there are Linux and OS X native binaries packages with all dependencies e40000, gnuradio these days. You can modify the dongle for HF reception, but performance and frequency capability will be quite limited.

Here’s eponics example output. Pages with related products. Check out the Diseqc Bus Functional Specification pdf for a better explanation with more detail.

When you see something weird, like commercial FM broadcasts at 27 MHz, what you are seeing incomplete filtering of mixing products. This intensity measurement proxy traces out the the envelope of the fringes and varies as a sinc function of distance between antenna.

The DJ-X11 also costs 17 e,onics more. A number of people have tried to match the ADC’s input impedance and both differential inputs by using baluns of various sorts. I have not yet completed the scripts to turn alt-az positions of the sun at my location into motor step commands. This is calibrated by disconnecting them from antennas and connecting every receiver to the same noise source.


They do it in a rather roundabout way but at least it is tested and known to work with their software. Since the rtlsdr receivers can but shouldn’t do 3. For addressing specific ports of the Diseqc switch tune-s2’s normal functions are used. This means the Haystack idea of two coupled Diseqc 1.

rtl-sdr and GNU Radio w/Realtek RTLU, E and RT

I had to add manual motor commands to tune-s2 which did support switches but not manual motor commands. Using sample rates above 2. Here’s a video of him using it to make a 3 dongle direction finder.

But the procedures might still be useful for someone. Notify me of new posts by email. It’s not recommended to use sample rates above 2.

Some come with a remote which is also pretty much useless. A visual introduction by 3Blue1Brown, Quadrature Signals: Acinonyx describes one way to doing this using a single strip of aluminum tape combined with a spring to connect it to the dongle ground.

Shortly thereafter keenerd assembled eloniccs into a relatively easy to use patch-set. C to run this script. To generate plots and signal eloonics for 52 Mhz to Mhz with a gain of 30, sample rate of 2. With it he has managed to pick out the transit of the milky way at the neutral hydrogen frequency using rtlsdr sticks and a pair of yagi antenna.

Unfortunately my measurements of the dish motor shaft flat-to-flate size were off. Thankfully, you won’t have that problem with NooElec! Have one to sell? It would also be a good idea to use some low loss coax and keep it as short as possible.

Because I can use the default directories I keep it running like the below, but anyone else should make sure to set -d2. If you want to use the data in gnuplot you have to sort it and make sure the header is commented out. To enable a block, select it and press ‘e’. But, someone might, so I’m leaving it here to be indexed. Don’t see what you’re looking for? To combine the results from multiple dongles just cat the files together. In the stereotypical ezcap boards you can test this by connecting an appropriately long wire antenna to the right side of capacitor 17 on EzTV 1.


This gives better dynamic range for the visual FFT but demodulated quality is not changed.

Be the first to review this product. While the sample rate or tuner width I set may be some large number, it’ll become obvious what the limits of each other as you scan about and see the signal folding or mirroring.

If you’re like me and run an older distribution then your Qt libraries will be out of date and lack a function required for generating the name of the files to be saved when recording. The E tuner datasheet has been released into the wild.

The rate of scan is about 0.

His post shows the results of a gnuradio block he coded that does all the correlation math to align the samples from each receiver which are out of step due to the way USB works. F to MCX for the other style dongles. As I understand it the switch chips are sa that “look” for dongle i2c traffic. By not waiting for PLL lock at all and always leaving the i2c repeater register enabled tejeez reports retuning speeds of up to jumps per second are possible.
