Unable to change serial number on second SDR dongle- windows 11 OP system-SDRTRunk

[Colincolin30]

I am trying to set up two SDR dongles to use SDR Trunk.
I want to get a wider band coverage. To do so you need to change the serial number on the second dongle.
Its a stock standard SDR dongle v3 nothing special. The first dongle is working on on SDRT Runk.
I have used the recommended software "tool" but get an error report which I have printed out below in this post.
I have contacted the manufacturer and had no reply. rafaelmicro.com
Any suggestions where I go to from here?
cheers Colin VK2JCC

Looks like you botched it, there are supposed to be 8 digits..

If it's a legit rtl-sdr-blog v3......

Make sure that dongle is the only one plugged in..



Download this and put it in your rtl_sdr_64bit folder

RTLblog01

drive.google.com

After you have placed it in the folder, that dongle being the only dongle plugged in , open a cmd window in that rtl_sdr_64bit folder ( you can type cmd in the folders address bar then hit enter)



In the cmd window type

rtl_eeprom -w RTLblog01

Press enter

Once it's done, leave the cmd window open, wait a few seconds , unplug that dongle & plug it back in..

In the cmd window run

rtl_eeprom

Do the output now look normal?

Thsnks for your reply.
I have not been able to change anything yet. I am well aware you need 8 numbers. That's what I am trying to do.
I think you missed the point I made in the email.
Any advice how to 'enable 'the change of serial number.

A forum search found the same issue.

This post SDRTrunk and 2 RTL2832 Tuners

Simple instructions:

Thanks for all the help. I reached out to Nooelec support and I needed to run rtl_eeprom -g realtek and then I was able to run rtl_eeprom -s 00000001. I now have the serial number enabled and written on both SDR tuners.

This is dependent on if your RTL-SDR is from Nooelec. It might or might not work with others. Especially RTL-SDR Blog dongles.

Your command string in your post #1 above shows you are trying to change serial number to 02, which is not 8 digits. If you have typed 00000002 it might have worked.

I believe you can run up to two with the same S/N. I run two V4 in SDR Trunk with no problem and it utilizes both.
