SDR# SDR# not showing signal

Remove all the sdr's, only plug in the blog v4

You need to run zadig specifically for the blog v4(only needs to be done once per pc)

your task bar, devices, should show Blog V4

Did you use Zadig to replace the drivers for your RTL-SDR devices. If so, what does Zadig report as your current driver. Should be WinUSB.

If you tune to a known active control channel, what does it show?

this is what I get when I ran Zadig. All 3 of them are on this version.

Did you rename the blogv4 at some point?

If you download this
rtl-sdr-64bit-20250126.zip

(With only the blogv4 plugged in)

Extract it, open the folder, type cmd in the file explorer address area, press enter, in the cmd window type
rtl_eeprom

What's the output?

You have 3 showing in dev manager. What happens if you unplug 2 and just try 1?

same thing. nothing will receive in SDR#

Perhaps change the Product string back to Blog V4

Honestly.. renaming it fixed this whole issue for me. I can see signals now in SDR#. Thanks for the assist. I never thought changing the product name would cause this much issue for me.

I remembered reading it at some point, it was on the rtl-sdr site for the blogv4 (at the very bottom 😀)
