Cool app. With my DVB-T dongle, I can see signals from 25 MHz to 2200 MHz. I can actually tune all the way down to DC with the app, but my antenna is not matched for that range. I assumed that is out of band for my dongle as well. I really like the waterfall and live spectrum. User experience is seamless with all the features advertised. I only gave 4 stars because I feel that there are other features that Mr. (Dr. ?) Marinov could add to make this app truly stellar. A few ideas of mine: - Live constellation view outside of FM mode. I would really like to look at BPSK and QPSK constellations that could be generated in ISM bands - Demodulation of other signals such as PSK and FSK. - Settable integration bandwidth for power readings - Adjustable resolution bandwidth - Markers with deltas so that I could compare power levels of two or more signals (or portions of a signal) in band. - Adjustable power scale and resolution in spectrum and waterfall - Absolute calibrated power in dBm on the spectrum. That might be pretty hard because of the array of devices that this app can use. - Different color maps and adjustable time resolution for the waterfall
The best app out there for SDR dongles. I've been using these dongles for a while on my Linux box, and finally I can carry it with me everywhere I go. Is there was to make this SDR Touch Key icon disappear as most other apps do when you upgrade them to pro?
Waiting for support for SDRPlay Works great and has options for IF input and use with an upconverter. Well worth the price.
I bought the key but have troubles I have a Samsung S2 I9100 with official Android 4.1.2. The SDR App starts normally and working good, but when i try to press OFF button, or exit the application any other ways the phone is reloaded or hangs every time. May be i do something wrong?! Can You help me, please. I able to help with collecting any debug information if needed. I have SDK and adb installed. The phone is not rooted, but i can root it if needed! Hope that situation will be fixed. I read a FAQ section and found a question about "The application runs for a while, then crashes". I create an external power USB male to female pair with external power to female only. Nothing changes. Problem exists!!!
Awesome, works exactly as i'd hoped if not better. check your hardware compatibility and make sure you have correct dongle first and a USB OTG cable (use free ver to see if it works before you complain it doesn't work, because it does work - very well for the price.) Brilliant app, been stting here listening to air traffic for past hr works great, scan works well too once you save some frequencies, would like to be able to adjust time scanner takes to jump to next frequency after silence but thats only something nice to have, oh and being able to transfer frequencies from one category to another by check box in a multiple transfer would be cool too, though you might be able to, i'm still finding my way around it but is very intuitive. Worth the money when it works so well. Cheers! Samsung Galaxy S5 (rooted)
RTLSDR App Well written, stable for running on Android phone. It's interesting to use SDR where you happen to be. Problematic power consumption running from phone battery, you'll really need external power.
