Hey guys, I'm sorry I haven't been monitoring this topic for a while. Some updates from me on the following issues: Cannot change frequency as the screen does not respond to touch This was a bug with Huawei devices. It has been fixed in the latest release. Please make sure you update SDR Touch...

Hey Naiku, No update for you I'm afraid. I still agree that car interface should be the next new feature introduced in SDR Touch. However as you have probably noticed the last couple of updates were maintanance updates. I am sorry I wasn't able to deliver a car interface in 2016. Martin...

This is a great question :) The Live Channels app is currently only available for a very small number of TV boxes. This means that more customers can benefit from Aerial TV than Live Channels. For this reason I will concentrate working on Aerial TV for the time being. If Google extends support...

Hey guys just fyi, if you ever wanted to use your RTL-SDR dongles to watch TV on your Android device make sure to check out my new project Aerial TV on XDA: https://forum.xda-developers.com/general/paid-software/android-4-1-aerial-tv-dvb-t-t2-rtl2832-t3591124 It's basically an app that uses the...

Hey guys, If anyone is still interested in this project, you can check out the app that I've written that plays TV using the RTL2832 dongles without root. It's available on Google Play to download. Link to forum...

Description Aerial TV brings DVB-T and DVB-T2 to Android using the cheap RTL2832 dongles. No root required. If you already own an RTL-SDR dongle with the RTL2832 frontend then you are ready to go. Just plug it in with USB OTG cable and follow the on-screen instructions. These dongles are easy...

Hey, Sorry for not following the thread for that long. I am still supporting the project. In the last year, I worked mainly on the driver (almost 100% rewritten). This was required since Android 7.0 was not compatible with the old driver approach. I also added a (beta) driver for SDRPlay. All...

SDR Touch v.2.65 was just released! Although it has some bug fixes, the major change is the support of 6 new languages: Bulgarian, Germain, Italian, Polish, Russian and Ukrainian! If you find any problems in the translation or you would like to help translate SDR Touch in your own language, go...

Hi. I do agree GUI needs a refresh. The plan for 2016 is to get a friendly in-car interface up and running :) As for the dialog, it is the Android OS asking you for permissions.

I don't have an official board but I am indeed collecting ideas from people like you guys :) It is certainly possible to respond to these events and I will look into this in future.

SDR Touch v.2.6 was just released! New features: Baseband recording and file playback Direct sampling support for full-band receivers Improved SSB image rejection Fixed tuning step Manual filter bandwidth Improved accessibility Bug fixes As usual, please report any bugs you find. I am also...

Hi Christoph, I will be investigating having AF (and possibly TA) in future versions of SDR Touch. I am planning to create FM radio only interface that will function like a normal radio, without the bells and whistles of SDR. However, I am not aware anyone has done something like this with...

SDR Touch v.2.1 was just released! New features: Scan pre-sets feature Improved interactivity and speeded up FFT display Minor GUI tweaks Crashes fixed The scan feature works by scanning your current pre-sets! Make sure you have pre-sets before using the feature. Any feedback is welcome...

Does SDR Touch 2.05 solve your problem?

SDR Touch v.2.05 was just released! New features: Improved audio quality for weak signals in high quality mode Tweaked waterfall colours GUI text now scales with screen resolution Fixed crash when upgrading from SDR Touch 1.7 A couple of stability fixes Download

SDR Touch v.2.0 was just released! It took a while but it is finally here! The app has been completely rewritten from scratch. This will allow numerous future extensions - adjustable bandwidth, FFT size, plugins, separate GUI for in-car use and many more :) Stay tuned for SDR Touch 2.x...

Ok. Here's what you could try: Start the driver manually (like in your screenshot) then open SDR Touch and click "Remote" and enter 127.0.0.1:14423 and tell me if anything changes.

Hey sorry I haven't responded for a while. I don't have a Motorola phone unfortunately. However, I am in the process of rewriting both SDR Touch and the driver from scratch and expect it to be released in July. It should solve tons of stability issues. If you can't wait till then, I can give you...

Hey, sorry guys I'm not responding. I will be very busy for the forthcoming month and afterwards I'm going back to developing SDR Touch. You should not start the driver manually. Just start SDR Touch first and it will load and start the driver automatically.

I'm thinking about that :)

Hi. An easy solution would be to tune down the gain setting in SDR Touch. The reason is when there is a strong signal present, the RF front end of the dongle can get overloaded and will "spill" stuff everywhere. Unfortunately you can't do anything about this in software. The automatic gain...

The messages say failed to set modules. So there's something wrong with the modules (probably not compiled for the right kernel?). Read the dmesg log it should shed some light.

SDR Touch v.1.7 was just released! After nearly 3 months of development the new version is here and SDR Touch is better than before! New features: FM is now in STEREO New audio recording feature for PRO users Improved reception and audio quality. All filters were tested for quality and all...

I suggest a restart of your device. Otherwise the best way to go is to start the driver from the launcher (via its icon) and press the "Start stream" button and provide me with the output you get. There are some stability issues I am currently working that can leave the driver in an non-working...

Hi. For kernel revision you should supply just g25ab3af. Don't write 3.1.10-g25ab3af

Hi :) 1. Should be ok. Although I always recommend putting your phone into airplane mode to minimise interference. 2. Kind of. Nothing prevents Android from killing it whenever it feels like if the app is not showing on the screen. Usually it should be ok. Although as soon as you minimize it...

+ 1 :)

This is because the script works only for Nexus 7 kernels, sorry. The reason is that it is using the source code for the Nexus 7 kernel, if you have the source code for the kernel of your Asus, you should be able to modify dvbn7comp to suit your needs. The reason for having dvbn7comp is as to...

Hi. The high-pitched noise is a side-effect of the approximations made to the algorithms so SDR Touch runs on low-powred ARM CPUs (fixed point arithmetic introduces more errors than the floating point one used in traditional SDR). I am sure there is a way to reduce it and will be trying to fix...

Good idea. Possibly yes. But even now synchronization is a headache. If I have more time will look into it in more detail. I am working on the next version of SDR Touch now but can't promise when it will go out. A lot of things will change in the way SDR Touch works and the driver works. From...

Hi. This was a feature that was present in the first version of SDR Touch before it was split up into a driver and an app. Now it would be extremely difficult to achieve since they are apart. The driver needs to know that as soon as device is connected SDR Touch needs to be started but what if...

I'm glad that worked well for you :) The high-end devices (Nexus 7 for example) have plenty of CPU power left so they could do miracles, as for lower end devices what we already have is close to their limit. But you are right scanning, speed improvements, stability improvements, most notably...

Try restarting your device. This sometimes could help. Also try reinstalling the driver app, you might have accidentally clicked on "Deny" when you were asked for root permissions. The rtl_tcp should be running at 1.024 msps (take a look at the default parameters in the driver app), otherwise...

You will need a USB dongle in order to use SDR Touch.

Nexus 7 is fully supported (I am developing SDR Touch on a Nexus 7) so this is certainly a really weird issue! My bet is there's something weird going on in the network.

Unless you download an app from the market that does this thing for you, there is currently no way I'm afraid. This is something that would appear in one of the forthcoming version of SDR Touch!

Hi Pez, What device are you running SDR Touch on? It seems like the cause might be that the Android device you are using does not have enough CPU power to run SDR Touch properly which could cause the buffer starvation you are describing.

What arguments are you using for the rtl-tcp? Are you sure the rtl-tcp is running on port 1234? Also, make sure the sampling rate is 1024000 samples per second. And some routers, according to the setup doesn't allow wireless and wired clients to communicate, so check that as well. You need to...

Yes! Exactly! That's my point! Now there's a driver anybody could utilize easily in their app (I know there is a lack of documentation, but feel free to ask me, to use the driver it's literally one line of code). So if there are enthusiasts to start their apps based on the GNU rtl-sdr port, I...

From what I know the project SDR Touch will not be suitable for DAB. It should be doable but will require a different back-end architecture than what SDR Touch could offer since SDR Touch is mainly designed for analogue reception and is highly optimized for it. Adding additional modules would...

SDR Touch v.1.6 is out in the wild! It features: Waterfall Speed optimizations Fixed squelch clicks Fixed a few crash cases Download Note: This version features a brand new FFT (Spectrum) engine! It is about 3 - 4 times faster than the one in v1.5. If you experience any problems with the...

Recording and exporting are some of the functions I am considering implementing soon :)

Compiling kernel modules Ok, guys. I've made a script that will compile the kernel modules for Nexus 7 for an arbitrary kernel version. Here's what you need to do: Make sure you are running Linux and have make and git already installed Download dvbn7comp and put it into a new directory. Make...

Hi, could you provide me with your email address (via PM or to martintzvetomirov at gmail)

SDR Touch v.1.5 was just released! New features: Presets SDR Touch is back on Google Play! Download

I would indeed recommend you try it on a computer. Keep in mind that some dongles require more power than what some Android devices can supply so you might actually need an externally powered USB hub or a powered OTG cable.
