RTL-SDR usb "stuck" frequency

Post by warenbe » Sat Mar 20, 2021 8:29 pm

Hi
i bought a RTL SDR v3 key from the french reseller (found on rtl-sdr.com website)
using sdr# or sdr console v3, i have an issue : the frequency does not change...
it happened after few hours of usage.

let me show you:
this GIF show the problem:

(sorry gif to big to be hosted on the forum)

let say i'm with a frequency of 466 Mhz, as you can see i get some pogsac signal.
let change the frequency: it does not change :(
to get some changements, i must go 400 Mhz lower at least !

does someone already had this issue ?

some test i made:

i tried to put the Keenerds driver and it seems that the dongle is working as expected now with SDR# (i can change the frequency without problems)

with console SDR v3, the driver does not work (console SDR say it can not find the dongle). using the default driver, it's still broken with console SDR v3

so, i suppose it's a problem with the default driver ?

does anyone had the same issue ?
does anyone has an explanation for this bug ?

The last thing I remember about SDR console is....that everything you need is already self contained within the app other than just running zadig. Don't drop anything into its directory.

Yep that's what i discovered
but it does not explain why, with stock driver SDRsharp and SDR console does not change the frequency.
