[Solved] DVB-T + FM + DAB Tuner and HDSDR Program Installation: Maximum Frequency Set at 1.600Hz

Good morning,

Today I bought a DVB-T + FM + DAB tuner and started to install the HDSDR program (according to the instructions found on the internet).


After installing the HDSDR program, in the options I chose the tuner connected to the USB port and the program started. I wanted to wash the frequency eg 97Mhz and here is a surprise.
The maximum frequency I can set: 1.600Hz

Bought a tuner on a popular auction site: DVB-T + FM + DAB

I will describe step by step how I installed:
Using the program, I replaced the drivers:


Then I reached for the ExtIO_RTL2832.dll file from the HDSDR software manufacturer's website


I copied the file to the directory where the program is installed:


Then I restarted my computer and launched the HDSDR program

In the Select Input settings I chose: Generic RTL2832U OEM


The program has started, but I can only set the maximum frequency: 1.600Hz


Ext10 settings:


Please help,

Today I fought half a day and gave up

I did everything according to this instruction:
http://ywd.pl/projekty/odbiornik-sdr/

So I downloaded the ExtIO_USRP + FCD + RTL2832 + BorIP-1.2 BETA10_Setup program and did it step by step according to the description.

In the program, I can set higher frequencies, e.g. 200Mhz,
but the program shows the same peak on the spectrum all the time, e.g .:

I set 94Mhz


I set 106Mhz, it still shows the same (i.e. no FM stations can be received)


The operating system is Windows 7 Pro 32bit
Before making another attempt to install HDSDR and ExtIO, I restored the operating system from the image

I always do this:

- I am waiting for the drivers to be installed (for 7 I suspect that I need from the disc) [8.1 and 10 it downloads itself].

- I overwrite them from the Zadig level

That's what I do like this:

- I put the tuner into the USB port, the win7 system detects it and wait for it to install the drivers (the drivers have been installed)

- I overwritten them Zadig, I tried, I tried, also with ExtIO_USRP + FCD + RTL2832 + BorIP-1.2 BETA10_Setup

Only I'm installing the program HDSDR

From this topic https://www.elektroda.pl/rtvforum/topic3182271.html I downloaded the package from HDSDR and the same problem occurs,

And so I wonder if this tuner will work with HDSDR

I reformatted the drive and put the win 7 operating system back,

I downloaded the attachments from post # 11. I did it step by step as you described in post # 11.

And unfortunately the effect is the same as described in post # 1

I dismantled the tuner and the following integrated circuits are mounted in it:
- RTL2832U
- Rofoei Micro R820T2
- ATMEL178
- Stabilizer: AMS1117 3.3
- quartz: 28,800
- Transistor A7 near the socket to ground, two legs shorted to ground, middle to the hot antenna wire

EDIT:
After removing the tuner from the USB port, the program stops working, i.e. the tuner, the HDSDR program can only see why the band is narrowed (post # 1)

Unfortunately, I bought a third USB receiver and it doesn't work either.

I went to the computer repair shop, they reinstalled windows, but they didn't manage to start the receiver.
Apparently you need to upload a new batch to the RTL2832 system. Soldering the dice and uploading the modified charge is PLN 200.

So I let it go because it is fiction.

Added after 3 [minutes]:

Converting the USB TV tuner receiver (such as in post # 1) to the HDSDR tuner is not profitable.

It is cheaper to buy the original HDSDR USB tuner on a popular website.
