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

If it is an antenna from the set, it is usually of very poor quality. And how many stations are received on an ordinary radio receiver?
A suitable antenna is the basis for reception.
I propose to build an external antenna for the roof or balcony. There are many descriptions of antennas for different bands on the electrode.
For the most interesting bands of 144 MHz and 430 MHz, there is an antenna in this topic:

On VHF, he even picks it up on his finger.
I would check the antenna cable first, especially if you have a Chinese cable, a grommet or an original antenna. Some antennae have a hair-thick hot vein concentrate, and it's not hard to break it

If you have an antenna added to the tuner, it is definitely the antenna's fault

Hello!

Where is this PPM function from correcting the shift?

What program?

Hello!

I installed both HDSDR and SDR #. The case is as follows:
SDR # very few stations, 137 MHz aviation complete necrosis, 173 MHz I receive something there, but quiet, VHF radio is ok ... for me this program is poor

HDSDR many more stations, 137 aviation warszawa-radar very good, cb band very good, except that 173 MHz data transmissions only, as if encoded at the same frequencies as in SDR # speech was received, and on HDSDR no VHF ... spectrum I can see the station, but the voice is very modulated ...

What to do to make SDR # receive the same as HDSDR, and what to do to make sure there are ukf's in HDSDR

Change the gain in the settings.

Here is a plugin for SDR # which already has something like a scanner http://www.sdrsharpplugins.com/
I recommend version V1.4 as it works as fast as possible
As for the most important SDR settings # because this program is the best
1. In the "Cofigure" tab set the correct frequency "Frequency correction"
First, tune to a well-known VHF radio station, then listen and "catch", for example, the 134.225 Warsaw radar and fine-tune it (the half-zoom is best visible if it is inside).
2. For listening, in my opinion, it is best to set everything unchecked in the "Configure" tab and the RF Gain to the maximum
3. The computer must have a minimum USB 2.0 processor with at least 1.2GHz
And this is the most important thing for further action


As for which receiver to choose, the best one is RTL2832U (it is no problem at auctions), secured input, covers the entire range and is sensitive, I compared it with several "normal" scanners and it won or was identical with each one.
As for connecting a normal antenna, because you will not hear anything on this set, it is enough to cut off the original antenna and mount a socket on the cable, even an ordinary TV
At the beginning of the fun you can use the popular mesh TV antenna, but without any amplifiers !!! and preferably without this mesh in the back it will be more omnidirectional On such an antenna you will receive virtually all planes over Poland, trains, ambulances, guards and other services at least 20 km and even 60 km
The 400MHz band, there are smaller ranges, but something is going to catch
And then just think and it's best to make an appropriate antenna for the band that interests us the most (for a few zlotys).

Whether SDR # is the best for your taste, but I recommend SDR CONSOLE v2

Two heads are better than one, so maybe colleagues will tell you why HDSDR does not work for me. I have Not Only TV RTL2832u / FC0013, the system is Windows MX which is a truncated professional version of 2002 SP2. I did everything step by step according to the instructions (http://www.hmmb.nl/downloads/RTL2832U-installing.pdf), I replaced the drivers, pasted the new librtl2832 ++. Dll to the installation folder, in device hint I entered RTL and the flap. I run and even don't catch radio stations. My device manager looks like this:

You do not have any drivers for the tuner installed yet. Point 5 of the description.

http://sdrsharp.com/downloads/zadig.zip

I did step 5 during the installation. To be sure, I did it again and it looks like Zadig is not replacing my drivers. Device manager remains unchanged as mentioned above. And in the next step after replacing drivers, something like this appears to me:

It seems to me that you are installing drivers for some other device.

What appears in the ZADIG list when you select Options> List All Devices?

I have: USB 2.0 Video, USB audio device, Bulk-In Interface 1 and Bulk-In Interface 0.

What is in the VID and PID fields of Bulk-In devices in Zadig?

Bulk-In Interface 1 mam VID: 1F4D PID: C803 MI:01
Bulk-In Interface 0 VID:1F4D PID: C803 MI:00

In my eye you have something mixed up in the system, remove both devices in the device manager and after this procedure, remove the tuner from the USB port, wait a moment and insert it again and then show what has appeared in the device manager.
I do not know if it is not the fault of your truncated Windows.

For any of the Bulk-In, Interface should be 0BDA VID and PID 2832 or 2838

EDIT:
What do you have in VID and PID at USB 2.0 Video because I buried in my tuners and I think that NotOnly is like that?

Lysy thanks for your help. I do not want to clutter the forum, so I will try to install it on another laptop with a different system on Sunday because I also think that something is not working in my system. As soon as I check, I will contact you at PW.

problem solved. The culprit turned out to be a truncated version of the system and its drivers. On normal XP, it flies. Unfortunately, the tenderness is terrible. Gain to the max and you can hardly hear radio stations, let alone receive weaker signals. I do not have a "normal" antenna at the moment, so I use the thumbnail included in the set.

I have short and frequent breaks in my pickup. The sound is hoarse. Has anyone encountered such a problem?

Yes, reduce the receiver bandwidth, you probably have 2MHz and the computer is not working.

You answered yourself Use a "normal" antenna and you will see that the circuit has a really good sensitivity.

Could you please guide me on how to do it in HDSDR program? I changed the settings, but I guess I missed the right one.

Isn't it better to get interested in SDR Sharp?
https://www.elektroda.pl/rtvforum/download.php?id=565446

Is there a program that can scan the full band - spectrum analyzer 50-860MHz? The point is for me to see the whole band, not just a few MHz.

Hello

I don't know Linux programs, so I don't comment on that.

SDR Sharp and HDSDR are very popular for Windows.

I suggest checking one more program:
SDR RADIO Pro
Has RTL SDR support - Realtek RTL2832U
The program is noteworthy, and it has already been mentioned on the forum:

Version 2.1 Release - license until January 8, 2015.

https://www.dropbox.com/s/b1kqas6o5ofpdy0/SDR-RADIO-Pro_v2.1b1640.exe

RTLsdr.dll libraries required for the program:

For this program you need more powerful hardware, as it has much greater requirements than SDR Sharp or HD SDR.

The recommended minimum system configuration is:

Windows XP or later, 32-bit or 64-bit
Core 2 Duo @ 2GHz or more or i3 or better.
Monitor resolution of 1368 x 768 or higher.

Thanks. I used to play with a cable TV analyzer. In a second or two, it scanned and traced the entire spectrum on the screen. I am looking for a program with this functionality. Non-vibrating spectrum but rather signal strength graph.
I was looking for but there is probably nothing like that.

As far as I know, such a program does not exist, and watching the 800MHz band is rather pointless, because you will not see anything anyway.
I don't know Linux programs, so I don't comment on that.
For Windows:
In SDR Sharp, you can set the highest Sample Rate in Configure to 3.2 MPPS. Then the widest band is viewed. It is a few MHz. In HDSDR you can see a much wider band, more than a dozen MHZ ...

Such a program of course exists and it is not about displaying the SR which for the R820T is up to 3.2MSPS (i.e. about 3.2MHz). In HDSDR you will not see anything else because the hardware does not allow it!
What the TM85 asks about is the analysis of the entire bandwidth received by the dongle, not the number of samples received in a given bandwidth!
Please search rtl-sdr.com for frequency scanners (incl. Plugins for SDR #). Some time ago, there was also a link to a separate software that "scanned" all available frequencies and a graph was made on this basis. Thanks to this, I know at what frequency "something" works and what I can expect in my area.

I must have misunderstood the question. Thank you for the correction.

SDR # plugin that scans the entire band.

What are the hardware requirements for SDR Sharp?
Is USB 1.1 enough?
