Description

Use an OTG (on-the-go) USB cable to connect your HackRF/RTL-SDR to an Android phone/tablet and this app will visualize the RF spectrum (frequency magnitude and waterfall plot)!Browse through the frequency spectrum just by using scroll and zoom touch gestures. Additional features as of today are:- Many settings: FFT size, averaging, peak holding, color scheme, ...- read samples from a file (generated by hackrf_transfer tool or by rtl_sdr)- AM/FM/SSB audio demodulation- adjust squelch and channel width- Record to a raw IQ file compatible with hackrf_transfer, ...- Bookmarks- rad1o supportRead the manual for more details: https://github.com/demantz/RFAnalyzer/blob/master/doc/rf_analyzer_manual.mdDue to time constraints the app is currently not actively developed anymore.I also try to keep the app stable and as bug-free as possible. Bug reports are always welcome and I try to find the time to fix them! Note that there is a logging feature in the settings which helps a lot with trouble shooting any errors.Interested in the latest updates? Join the beta program: https://play.google.com/apps/testing/com.mantz_it.rfanalyzerPERMISSIONS:This app uses the INTERNET permission only to connect to the local rtl_tcp instance used by the RTL2832U driver. The WRITE_EXTERNAL STORAGE permission is only used to write log files to the SD card (disabled by default).WHAT YOU NEED:In order to use this app you will need:- A HackRF or an RTL-SDR dongle (this is obvious xD)- An Android device that either supports USB OTG (please google if your device supports OTG!) or has an USB host port- An USB OTG cable (costs about 3$) to connect the HackRF/RTL-SDR to your Android device (not needed if your device has a full size USB host port)- Only for RTL-SDR: The free RTL2832U driver from Martin Marinov (https://play.google.com/store/apps/details?id=marto.rtl_tcp_andro)IMPORTANT:The HackRF/RTL-SDR is powered by the Android phone/tablet. Some phones or tablets might not deliver enough power on their USB port to power the HackRF/RTL-SDR (power issues are often caused by low quality USB cables or OTG adapters). Also notice that doing the necessary digital signal processing is very CPU intensive and though I did my best to optimize the algorithms the app still needs a decent device (I recommend 2 CPU cores or more) to run fluently. Please use the 2-hour refund period provided for every Google Play app to test functionality and refund the app if it does not work for your device!

Can u please develop an app to limit the frequencies coming out of my phone? I want to have an adjustable method to cap it at 10 Mhz. These waves are burning my hands from my phone. Send me some money when your rich from this app, give me 5%
