SDRTrunk .0.50. Two Dongles - not being recognized (have the same name)

[mistermightymoose]

Hello,

I'm very new to this, so please bear with me. I have SDRTrunk V.05.0 Alpha 6 working. I am monitoring an 800 mhz band (Canada-Ontario-Sudbury District-Greater Sudbury-Wahnapitae).

The one antenna that I have is able to be used. It shows up as 820T. I purchased a second dongle and thought that I might get more traffic as it the program could tune into two communications at the same time.

The dongle is a different brand, but it seems that the software is recognizing it as the same type of dongle. So, I have two tuners that show up as 820T.

Both have different antennas.

The one seems to work best when I set the PPM to 31.4.

When I go into the second tuner, because it has the same name... I'm running into issues where I can't set a different PPM because it thinks the tuners are the exact same. Any suggestions? I'm not sure how to make them come up as unique so that I can set their correct respective PPM.

Thanks!

Look at info at the link below

Renaming Dongle - rtl-sdr.com

Use rtl_eeprom

Mine were both numbered 1, I changed one of them to 2, here is an example --

rtl_eeprom -s 00000002

Hello, I downloaded and ran the rtl_eeprom file. It opens a DOS window and immediately closes... am I doing something wrong?

You should run it in a command window.

Obviously. Yes. You can't run a DOS program by opening it from the desktop. First, you need to open a DOS window (command prompt), then navigate to the location where your DOS program is, THEN type in the name of the program that you want to execute (rtl_eeprom.exe) Be careful with this program or you could brick your SDR device.

For some reason, every time I would run rtl_eeprom it would look like it was loading and then just close. I ended up following the instructions here and I was able to rename the two dongles. How to Change Serial Number of DVB-T Dongle

The default behavior of rtl_eeprom is to just run, index your devices, list info on them and close. I presume this happens so you don't accidentally nuke your sdr dongles, but also really because its a command line program and needs parameters to carry out its function.

You have to specify a -d for a device number and then a -s to give it a new serial number. The program can be used to flash firmware on to rtl sticks, but I don't recommend it, it could brick the device. Actually, I don't even know if certain special firmware exists for rtl sticks or not, much like how cryto mining firmware exists to flash onto graphics cards and what not.

NAME
       rtl-eeprom - EEPROM programming tool for RTL2832 based DVB-T receivers

DESCRIPTION
       Dumps  configuration  and also writes EEPROM configuration.  Written by
       Steve Markgraf and incorporated in the osmocom rtl-sdr project.

       Use at your own risk, especially -w!

       Much software is available for the  RTL2832.  Most  of  the  user-level
       packages  rely on the librtlsdr library which comes as part of the rtl-
       sdr codebase. This codebase contains both the library itself and also a
       number  of  command  line tools such as rtl_test, rtl_sdr, rtl_tcp, and
       rtl_fm. These command line tools use the library to test for the  exis‐
       tence  of  RTL2832 devices and to perform basic data transfer functions
       to and from the device.

       Because most of the RTL2832 devices are connected using  USB,  the  li‐
       brtlsdr  library  depends on the libusb library to communicate with the
       device.

USAGE
       Writing bad information to the EEPROM will make your device useless.
