RTL-SDR - an SDR receiver from a cheap DVB-T tuner on a USB connector

It was necessary not to update the Elevator.
M.

Install the original drivers and then replace them. It helped me.

Information for those who have the SDRSharper program. There is a new version 05k, although the file is named 04k. I have tested it for myself and it works satisfactorily. Below is a link from where you can download the file.

And here is the rest of the version.

I do not recommend this file !!! It includes Trojan: Win32 / Spursint.A! Cl
And it's not a new version. It is from 31-May-2016

AVIRA PRO does not detect any Trojan. If you indicate a newer version of SHARPER - which as far as I know (I may be wrong) was not supposed to develop due to the infringement of SDR # copyright - then we will be grateful.

edi730 I have Norton Secutite Internet paid version and it doesn't show me any Trojan, I don't know what antivirus you have and where you got this information from. The last available version was v0.3h from 2015. Like a colleague lysy1980 he mentioned due to copyright infringement was not supposed to be developed, but maybe they did it quietly because since May there has been no mention of a new version anywhere. The only file I found on the web was on the other site as I gave it.

Even Windows Defender reported that the file contains a Trojan. Does not matter...
Do you have any bearing on the filter that will cut the radio band? Such 88-108MHz
I mean Polish stores ...

The file probably does not contain a Trojan, only you probably have a Trojan that tries to infect the archive when you open it.
The easiest way to build the filter is to build it yourself.

I have no time and no capacity. That's why I'm looking for a ready. And the Trojan message shows when sucking.

I add my version of the SDRSharper program in the attachment where you can listen from 1MHz up. Below 15MHz you need to give a gain of at least 90 percent not full and you can turn on RTL AGC, although if you have a good antenna you do not need to. If you have a bad antenna, if you want to listen below 15MHz, it is enough to connect the main cable of the cable without the ground. Anticipating subsequent entries about the alleged viruses, I post a screen from the file scan on the network.

For me, ESET ss full version did not find a problem in any of the peaks.

I have a question, because I want to buy this receiver: http://allegro.pl/radio-programowe-sdr-rtl2832u-r820t2-wysylka-grati-i6406149070.html#thumb/1 I have a question whether the antenna included in the set is suitable for anything? Mainly I wanted to play listening to the police, for example. My police station is about a kilometer in a straight line. The buildings are not very large, because I live on the outskirts of the city. The airport from which gliders take off, etc., is about 5 km away. Here the buildings are bigger as it passes through the city center. Any hope for any pickup? Alternatively, I would like to ask for some advice on how to make an antenna to receive, for example, this airport. Best regards!

In my opinion, the antenna from the set is suitable for picking in the ear, although the cable is a bit disturbing and for safety you need to stick this tip well.
In order not to lose the warranty, immediately buy a grommet for a slower antenna socket and make an antenna depending on what you want to receive
For me, an open dipole works well for me

As for the police, determine if you can listen to them at all, then determine what frequency they work on.
You can also listen to taxi exchanges or train communication from time to time.
If you are at the seaside, maybe some AIS data

I live in Katowice But I am close by: a police station, 2 hospitals and an airport. Do you know what is the name of the socket to which the antenna is connected to this receiver? The frequencies that interest me are in the range of 120-180 MHz. I do not know if I can build an antenna that will have this range, but I will search on the Internet. Can a new antenna be connected to the receiver by cutting off the old one and soldering two wires?

It's like me and the police from Katowice missed, but I wasn't looking either. I think I caught Tychy once.
Preferably through a grommet. This is from what I remember the MCX socket and the grommet probably is, but you would have to be sure. It's best to use a more serious socket - I don't like these little ones.
PKP is also good at catching.
It is best to have a separate antenna for an air band, and the other one can be identical only for another band.
Making such an antenna is a breeze. Anyway, you will always listen to something higher on the air band. Remember about the polarization of the antenna.

And it catches cool in Katowice on air frequencies? Do you have any formula to calculate the antenna length?

Look in the posts SP5ANJ

? = 300 / Fodb * k

Fodb - frequency in MHz
k - shortening factor typically 0.98-0.95

Hello, has anyone tested such a toy? Is it worth the money. The description says that there is a tuner inside with a converter.

As for the website, I have already ordered a few things there and they take into account the complaint if necessary. Sometimes you can buy cheaper what costs us four times more on the Allegro. Yes sdr tuners are half cheaper.

You did not take into account a few things, DUTIES, VAT, CUSTOMS CLEARANCE + income tax - if you want to sell something to the lagenie company, you have to pay the above-mentioned taxes + customs clearance - I'm not talking about those who "sell their electronic stocks" - although I also do not know if in the event of such a person's mishap, customers cannot be forced to pay Duty and VAT for the seller who did not pay it - Allegro will not hide anything, all transactions are archived and, at the request of the relevant authorities, customer lists of the seller are issued.

If you order something privately for yourself and possibly the parcel is detained by UC (believe that it happens quite often, the parcel is opened by UC), and you will receive a notification from Poczta Polska about this fact, it will also not be free of charge, sometimes it is simple - all you need is a screen of the transaction + or a confirmation from the bank or PayPal for payment by card, etc., sometimes you need to hire a Customs Agency, i.e. to pay DUTY + VAT (VAT is inevitable - Duty can be 0% or you will be exempt) + COST CHECK-IN. If you hire an agency, it is from PLN 50 upwards + fee for Poczta Polska, probably PLN 30 - payable when delivering the package by the postman.

In the end, you are stupid that you did not order anything, the goods will return to the sender and you are back with what you paid when buying.

End of OT

Thanks for explaining where this price difference might come from. For information, I compared the prices of tuners from the other side for PLN 43 with the Allegro auction of the same tuner with three adapters for PLN 139 from Gostynin, but that's not what I meant. I did some shopping for my own needs, not for sale and for large sums. My point was whether this receiver with a converter is worth something or not worth getting infected.

Did you look at page 19-20 of this topic ?? Until the knock you won't have it on the table and look inside, you'll never be sure ...

Hello,
I have a problem with frequency correction in SDRSharper (04k).
The Balice APP is 121.075 and I have around 120.932 - almost one MHz !!. How to correct it?
SDR # is ok (around 40ppm).

Paste the file settings.xml or look for a setting in it frequencyShift and before you set the frequency correction correctly.

Added after 35 [minutes]:

frequencyShiftEnabled change with False on True if you haven't already.
As for the desktop, I haven't found it, but maybe I'm blind ...

Hello, I have not been involved in this topic, but I have had SDR for a long time and listens to different bands, usually 170-185MHz.
I built a 137MHz quadrifilar helix antenna to receive weather data from NOAA satellites. I have one problem, the entrance to the roof is secured with a padlock (3-story tenement house) and here is the problem, if I put the antenna out of the window, e.g. a meter from the wall, I would be able to catch anything to be sure that the antenna is suitable for receiving it signal type? because it will be easy to get on the roof, but fly with it several times, etc.

The second thing, the person who familiarized me with this topic said that good reception will be provided by a mesh antenna placed horizontally without a mesh. It is about the bands on which policemen broadcast, etc.

The antenna is Quadrifilar Helix. The most ordinary.

@ wtełek1 What is the antenna you built it with? Yes, if you put the antenna out of the window at a distance of one meter from the wall, you will receive something under favorable conditions (instead of asking such questions, you would have done it a long time ago and found out for yourself ... preferably on a wooden brush - no, I'm not kidding!) The mesh antenna is the last resort, but in my opinion it is a dream come true.

Shift is in the FFT Display.
Well, it's going hard because:
For 144,800 I set Shift 97,000 and it holds when I call from Frequency Mgr,
when I punch by hand, you have to set it again.
For 119.275 (Kraków INFO) Shift 147.000 and the same.
Fun with every frq? I think I'm doing something wrong
The same in the SDRSharper 3h version

But why set shift when you can set PPM correction. In SDRSharper (04k) this correction is also set by clicking " config ". The basic rule is to select" RTL-SDR USB " not " ExtIO_RTL ". Then click config and set up PPM.

Thanks to Viking, I found your settings somewhere and after unchecking Shift and selecting in config only "Offset Tuning" all for now ok (ppm = 45)

I'm glad I could help. In case of any problems, I recommend that everyone read my manual available on the forum.

Best regards.

I recently came across the SDR slogan and I have these questions - there are several of them, but on one topic basically:
Does this RTL-SDR only receive the air signal? Inn. in words, is it suitable, for example, for the visual evaluation of the power of DVB-T TV channels in the antenna sockets in the rooms?
[I can see that the range is quite wide and it will probably also include: 470 - 790MHz (sheet 21 - 60), 790 - 862 MHZ (sheet 61 - 69), 174 - 230 MHz (sheet 6 - 12)]

What does SDR show at all when it is attached to a home satellite / DVB-T cable? Does it draw any graphs for the above channels? Power from the SAT socket will not burn something on USB in this mode?

Any info in this direction is welcome
