No, not much difference. If you already have a RTL-SDL Blog V3 or a Nooelec NESDR SMArt (v4 or V5), it is not worth getting a RTL-SDR Blog V4. The Airspy Mini is the real improvement.

Hi Derek, I mostly use the Airspy now. The HackRF is noisier but if you need its extra features (like if your are a Ham radio enthousiast or if you want to experiment more with RF) it could make sense ; it is also much bigger than the Airspy or the RTL-SDR.

The RTL-SDR seems to be higher because it has a lower dynamic range than the Airspy mini. The hackRF is lower because it is abit less sensitive. Also, the applid gain are not exactly the same. I tried to get them as close as possible but they don't all work the same way.

I am waiting too for Apple to allow the use of USB devices on their iOS products... Why can't you run Wingman ? Which tablet are you using ? I can run Wingman on my Samsung Galaxy Tab A9+ with Android 14 fine.

Hi, Here is a brief video about the latest TXAdvance update (v7.0), which introduces compatibility with new SDR hardware for much faster scan and wider bandwidth. Thanks! More infos: https://www.compasseur.com TXAdvance-SDR-comparison.mp4

Sorry it took a bit of time but export/import of exclusions is now here!

Thank you!

Then it might be the USB port not providing enough current for the SDR. Kind of half OTG.

When you plug a USB stick, can you open it from your tablet? Otherwise, many users are using Samsung Galaxy tab A serie with success. The A7 Lite seems to be quite popular.

Your dongle and cables look good. I am suspecting the tablet ; many unbranded, low cost tablets claim to have OTG although they do not have it. you can try 2 things : -look for an OTG tester app on the app store and check if there is OTG, -download this app https://play.google.com/store/apps/details?id=com.mantz_it.rfanalyzer&hl=fr&gl=US and see if it works.

Hi, what phone, dongle and OTG cable are you using?

Hi Paul, You buy the app through your Google Account. Therefore, any device which uses this Google account can download and use bought apps. So you can use TXAdvance on both your phone and tablet at the same time without problem.

In TXAdvance, you can create a custom TX at whatever frequency you want. When you are on the TX edit screen, in brand, go at the bottom of the list and select "CUSTOM". Change the low and high frequency limits to the walkie bandwidth. Then you can select the walkie frequency for this custom TX and its potential intermodulations will be taken into account.

Still in the list but thanks for reminding me. I'll bring it up!

Hi, it is already on the to-do-list. Thanks!
